PDA and Me Project  n

Background: "When I had a stroke more than 15 years ago, my right half of the body lost its sense of feeling. I don't know what my right side is doing. I have only one functional hand, my left hand. My right hand and arm are not only dysfunctional, but they could cause a disaster. It has sometimes caused not only injury, but also loss of stuff I was carrying in my right hand." - Sachiko

Problem: "I'm far behind from the current technology. I often thought about getting an iPhone or iPad, but I don't know how to hold it AND operate it with one hand/arm. I resisted getting into the iPhone-iPad fad, because using these gadgets requires two steady and functional hands. Nobody at Apple Stores or magazine articles gave me any answer so far. I'd appreciate if a student team could give me a hint/hand."

Aim: Explore designs that would enable Sachiko to handle and operate an iPhone or iPad.

Baby Lifter Project  n

Background: Carol teaches at Stanford. She has two herniated discs in her back. She had a percutaneous lumbar discectomy procedure for this in her 20s. Her general diagnosis may be tendinopathy or flexible joint syndrome. In addition, she has some RSI, severe tennis elbow, plantar fasciitis, and some neck and shoulder irritation. As a result of her condition, she can only lift and carry a few pounds.

Problem: Carol's inability to lift and carry more than a few pounds affects her role as a mother to her daughter - specifically in feeding, soothing, diaper changing, burping, lifting, and transferring her.

Aim: Explore design concepts addressing one or more of Carol's activities as a mother.

Design Criteria:

  • The design should be safe for both Carol and her daughter
  • The design should fit into her home, both physically and aesthetically
  • The design should not require drilling into walls or floors
  • The design should be able to be easily moved to where ever it is needed
  • The design should accommodate a growing child

Pimp Out Aubrie's Scooter  n

Background: Aubrie is a 2014 Stanford graduate in Product Design who has been using a wheelchair or scooter since age eight. She nows works at Google as a Associate Product Marketing Manager.

Problem: Individuals, like Aubrie, who use wheelchairs, scooters, or walkers have little opportunity to extend their personal sense of fashion and aesthetics to these devices. This is exacerbated by the fact that the equipment covered by health insurance or Medicare is often the most "basic" version with a plain design. Whereas one's choice of clothes, shoes, accessories, and jewelry are made on a daily basis, users of these devices have to "wear" the same equipment everyday and for every occasion.

Aim: Explore ways to add a personal aesthetic to Aubrie's scooter

Design Criteria:

  • The design should not alter or permanently deface or damage the physical structure or operation of her scooter.

  • The customization should be able to easily be installed, removed, changed, cleaned, and washed by Aubrie.

  • The design concept should not only work with Aubrie's scoooter, but also be flexible enough to be adapted to a number of popular / standard wheelchairs, scoother, or walkers covered by insurance and Medicare.

  • Reflect Aubrie's persona and aesthetic in the design. (Personas include casual / refined / elegant, modern / contemporary, smart / sporty, premium / luxury, user's age and gender, etc).

  • Consider fabrics, metal finishes, colors, patterns, lights, textures, and text elements.

  • Consider a variety of usage occasions such as home, work, outdoors, party, tailgating, etc.

  • The design should be inexpensive and easy to fabricate.

  • Consider designs that would enhance her scooter's visibility while crossing streets.

Therapy Game for Stroke Survivors  n

Background: Two-thirds of stroke survivors require some kind of physical or occupational therapy to improve their range of motion and coordination. Commercially-available motion-sensing computer interfaces such as the Leap Motion and Microsoft Kinect are being increasing used in medical and therapy applications.

Problem: The lack of compliance with a therapy regimen is a major barrier to physical improvement. Many stroke survivors who experience hemiparesis find it difficult to comply with their therapy regimen for a variety of reasons:

  • Since the benefits of therapy take a long time to become apparent, stroke survivors might mistakenly believe that the therapy is not working, become discouraged, and discontinue their therapy regimen

  • Since the therapy takes place at home rather than a clinic, there is a lack of encouragement and positive feedback from a therapist

Hypothesis: Using a motion-sensing computer interface to control a compelling video game such as Candy Crush or Angry Birds can create a therapy program that is both engaging and fun, which, in turn, can increase patient compliance with their therapy regimen and result in improved outcomes.

Aim: Design a game (or series of games) that employs a motion-sensing interface to create a compelling range-of-motion exercise game, with a goal of increasing patient participation and therapy compliance.

Design Criteria: The design must be extremely easy for a stroke survivor to use at home on their own computer. The gameplay must be engaging, rewarding, and addictive. The design should use a motion-sensing computer interface such as the Leap Motion or Microsoft Kinect controller. Desirable features include: 1) recording game use such as length of playtime and metrics related to range-of-motion and 2) increasing game difficulty with improvement.

Other: A Kinect Sensor Bar is available for use on this project.

Within Reach Project  n

Background: June is an older adult who increasing finds that items in her upper kitchen and closet shelves are now out of her reach.

Problem: Currently available step stool solutions do not meet her needs: some are too tall, others have a stepping area that is too small, and most do not have hand-holds to provide needed balance and stability during reaching. Finally many step stools are heavy and bulky, making them difficult to move and position.

Aim: Explore designs to provide a safe and stable means of accessing items on upper shelves.

Design Criteria: The solution must be easy to move and position, offer a sense of security during use, have a wide, non-slip surface, provide the proper height advantage, and be collapsable for storage.

Horseback Riding at Home Project  n

Background: The non-profit organization, Ability Production, provides services, information, and resources for individuals and their support communities who want to maximize their health and quality of life for those managing their spinal cord injuries as well as those experiencing MS, Parkinsons, or recovering from a stroke. The research and experience shared by Ability Production can benefit anyone, with or without a traumatic injury.

Horseback riding is an ideal activity for maximizing and stimulating movement in a "compromised body". The benefits of hippotherapy include improvements in balance, muscle strength, gait, posture and symmetry, joint mobility, sensory processing, and motor planning.

Problem: Most people are unable to pursue adaptive riding due to lack of local access, the high cost, their unfamiliarity with (or fear of) horses, inclement weather, or the difficulty of traveling to a riding venue.

Aim: Explore designs for an alternative to horseback riding that would provide similar benefits in a home or clinic environment for people with compromised bodies.

Design Criteria: The horseback riding alternative must:

  • be "bouncy", but stable (limited side-to-side and front-to-back movements)
  • include support "handles" for additional rider stability
  • accommodate the project suggestor, but consider designs to adapt the design for a range of rider's sizes and abilities
  • be portable through its ability to be disassembled, transported, and reassembled
  • allow rider access from the side and rear
  • accommodate riders who would mount and dismount from/to a wheelchair

Design Suggestion: Explore "Peanut Physioballs" as a seating alternative. They feature a unique design which limits movement along one axis to create a more stable, reliable, and consistent motion during use. Their round shape is advertised to provide rolling movements that engage the body's core muscles and deliver a safe, effective workout. The physioball allows up-and-down, side-to-side, forward-and-back, and diagonal movements that stimulate the neurological system; provide massage for the legs, gluts, and pelvic floor; improve postural alignment; and engage lymphatic movement.

Accessible Stroller for a Wheelchair-Using Parent

Problem: Parents who are wheelchair users have many challenges with the care of their newborns and infants. In particular, there are difficulties transporting the child as a traditional stroller would be difficult to manage for a wheelchair user.

Aim: Explore design concepts for an accessible stroller or a device that would offer similar features.

Design criteria: The design should:

  • provide a safe environment for the child
  • be easy for the parent to independently attach and detach a device to his/her wheelchair while in the wheelchair
  • employ mechanisms that are easy to use by a parent with limited hand dexterity and inoperable by the child
  • provide good forward visibility
  • accommodate the child as he/she grows
  • be adaptable to both manual and power wheelchairs

Balance Buddy  n

Background: The Balance Buddy project has been suggested by Sidekicks Ventures LLC, which is developing a new line of home assistive products for older adults.

Problem: Falls are the single largest health risk for older adults who live independently. They often have balance problems requiring an unobtrusive but reliable device for helping them maintain their balance and footing as they move around their homes.

When older adults begin to have balance problems, typically between the age of 70 and 85, they often use canes or walkers to maintain their balance and footing. Current commercial products can be extremely cumbersome to use in the home. Canes are difficult because they can be clumsy, topple over frequently, get in the way creating tripping hazards, and offer limited help for moving easily around small spaces. Walkers, although they provide steadier and more reliable help, are problematic because they are large and difficult to maneuver in small spaces and are also relatively ineffective on stairs. Both canes and walkers have the additional problem that they often require one or two hands to hold them, which leaves the user with a limited ability to use his or her hands for tasks in their home. This problem is compounded when the user needs to carry objects around a room or from one room to another.

Aim: The project goal is to explore design concepts for an easily managed device to help older adults who are having balance problems in their homes.

Design Criteria: The device should:

  1. provide reliable balance help for people who are unsteady on their feet;
  2. be able to be set aside without falling or moving;
  3. be light-weight and extremely easy to maneuver;
  4. be used with just one hand, freeing hands to the greatest extent possible for necessary tasks around the home;
  5. allow the user to carry objects (such as food) while moving around;
  6. make the user feel more confident and comfortable in their home compared to current commercially available canes or walkers;
  7. be easy to get into and out of;
  8. provide stability while getting out of a bed, a chair, or off the toilet;
  9. encourage its use.

Future Plans: The design needs to be lightweight and relatively affordable to manufacture. It can employ commercially available components or be an original design. Eventually the device will feature an industrial design compatible with a broader line of home assistive products, but for this project, the goal is to develop and test a functional prototype for a new type of balance aid. As mentioned above, it needs to roll or stand independently so that it doesn’t fall, or, alternatively, be able to moved nearby where it can remain easily accessible but not in the way of activity.

Other: The project suggestor is available to facilitate user testing.

Prosthetics / Orthotics Projects  n

  1. Quick disconnect system for lower extremity prosthesis

    Problem: Many users of lower extremity prosthetesis have difficulty sitting in smaller spaces, especially if there is limited range of motion of the remaining joints or other issues.

    Aim: The goal of this project is to design a quick disconnect device that is strong, very thin, and applicable to various types of prosthetic devices such that the components of a prosthesis can be removed or detached for more comfortable sitting without having to actually take the entire prosthesis off.

  2. Prosthesis sensor notification system

    Problem: Maintaining the fit of a prosthesis through out the day can be difficult for some people that have fluctuating edema of their limb. Pressure on the limb from walking will often change the volume of the limb such that the addition of a sock is necessary to compensate for the those changes. Some people have significant difficulty knowing when to add a sock due to decreased sensation in the limb, This can lead to problems with fit and function.

    Aim: The goal of this project is to design a simple pressure sensor system, to fit unobtrusively inside a prosthetic device, to alert the user when it is time to add a sock.

Projects employing inexpensive voice-recognition technology

Background: Thirty years ago, voice recognition systems were in their infancy. A typical system cost $3000 and required considerable user training to recognize just a few words. Today, the cost of these devices has fallen sharply while the performance has improved greatly.

Aim: Explore an application for a person with a disability using an inexpensive voice recognition product. Examples include enhanced computer control and accessibility for those with limited manipulation abilities, control of household appliances (lights, TV, music system), and operation of a hospital bed.

Design Criteria: The device should be appropriate for the user's abilities and be simple to configure and use.

Pooper scooper for canine companions of wheelchair users

Problem: Wheelchair users who walk their dogs need to clean up after them. Limited hand / arm strength and reduced mobility can affect the dog owner's ability to successfully perform both the collection and bagging portions of this task.

Aim: Explore designs for a pooper scooper system that will be easy for pet owners with a disability to use.

Design Criteria: The improved scooper design can employ commercially available components, but must be simple in design, lightweight, convenient to store on the wheelchair, easy to use by pet owners with limited hand / arm movement, and inexpensive to fabricate.

Creative Expression

Background: Most everyone has a need and desire to be creative through activities such as writing, painting, sculpture, pottery, jewelry, quilting, photography, singing, dancing, and music.

Problem: Existing tools supporting creativity are often lacking for people with disabilities. Movement difficulties often prevent an individual from fully participating in their chosen activity.

Aim: Explore ways to enhance creative expression for people with disabilities. This could include the creation of new activities or fabrication of new tools.

Suggestions:

  • Convert the user's existing assistive technology device into a creative "paintbrush"
  • Use non-traditional inputs such as residual movements or brain waves

Designing Your Afterlife

Background: Death is the most severe form of disability as one is no longer able interact with people or physical objects in the living world. What remains are only static artifacts - images, writings, and the recollections of others. Gone are one's personality, beliefs, expertise, humor, vision, memories, insights, and intellect.

Problem: With one's death, it is impossible to provide a full and accurate representation of who they were, what they believed in, and how they acted. The recollections of family and friends fade and disappear with time, leaving the departed one's legacy at the mercy of the living.

Aim: Explore ways to preserve one's essence after death. In the technology extreme, this might manifest itself as an interactive system that responds to queries, retells stories, relates experiences, shares expertise, and expresses humor. The pre-dead user would be able to create and program his / her eternal computer-based persona before her / his demise.

Enhanced bed control for veterans with spinal cord injury

Background: Veterans with spinal cord injury at the Palo Alto VA Health Care System use electric beds equipped with a pendant that controls their operation: head up/down, bed up/down, and foot up/down.

Problem: The buttons on the controller are difficult to activate as they are concave and require considerable pressure.

Aim: Explore solutions that would enable veterans to more easily operate their beds, including voice activation.

Design Criteria: Solutions could consist of a replacement bed control pendant or an overlay to the existing pendant.

Enhanced access to touch screen devices

Background: Touch screen devices - tablets, phones, kiosks, and computers - are becoming increasingly popular in everyday life, from personally-owned devices to those found in stores and polling places.

Problem: Many people with limited hand control have trouble getting their touch screen device to accept their 'tap' or interpret their gestures correctly. Sometimes the problem is caused by dry hands or fingers, but more often it's related to a user's mild fine motor problems. In one situation, this issue causes them to unintentionally slide their finger across the screen when they desire to tap, resulting in the touch screen device misreading this action as a swipe. Or they may inadvertently hold their finger on the selection too long, leading to misinterpretation as a precursor to selecting or copying a block of text.

Aim: Explore ideas that would enable users to make their selections more accurately on their personal touch screen devices.

Design Criteria: The solution should be an external adapter that can be used with an unmodified touch screen device. Light weight, low cost, and compact size are key features.

Magical Bridge Playground Project  n

Background: Magical Bridge is building the nation's first fully accessible and socially inclusive playground designed specifically for children with disabilities as well as children of parents who have a disability.

The City of Palo Alto has designated 1.3 acres of underutilized public land in Mitchell Park, located at 600 East Meadow Drive in Palo Alto, for the site of the Magical Bridge Playground. The playground will be adjacent to Abilities United and close to the soon-to-be-built Mitchell Park Library.

Problem: Although most of the park's design has been drafted, some aspects of the play areas could be modified for better access. Replacement play areas are sought to update the park with fresh attractions every few years.

Aim: Explore designs to address the following issues, creating a safe, fun, accessible, and inclusive park serving all children and their parents.

  1. to enable a child using a wheelchair to move between levels in the two-story playhouse

  2. to speed up the flow of kids on the slide:

    1. design an attachment to accommodate kids who can't get off the slide quickly or
    2. explore ways to permit parents to assist their kids at both the top and bottom of the slide

  3. to offer a new and innovative play and educational experience incorporating multiple senses, actions, and outcomes that is inclusive for kids with a disability

  4. to provide signage appropriate to playground users with visual impairments

Design Criteria: Designs should be safe for everyone.

Dog Leash Project

Problem: Wheelchair users who walk their dogs need their hands to both control their pets and propel their wheelchairs. A leash that is simply tied to the wheelchair can get caught under the wheels and interfere with the brake mechanism. And a strong dog may be able to tip the owner's wheelchair.

Users of rollators (walkers) also experience similar problems.

Aim: Explore designs for a dog leash system that will be easy for users to attach to their wheelchairs or rollators independently, prevent the leash from being caught under the wheelchair or rollator, and avoid being tipped over by a strong dog.

Design Criteria: The improved leash design can employ commercially available components, but must be simple in design, lightweight, easy to attach by pet owners with limited hand movement, provide a reliable release, and be inexpensive to fabricate.

Educational Activities for Children with Disabilities

Background: Resource Area for Teaching (RAFT) creates hands-on activity kits which nine thousand educators use to help nearly one million students master important concepts in school and after school each year.

A large percentage of the students these educators serve have disabilities (physical, mental, or emotional). RAFT is particularly popular with these educators because our hands-on activities often seem to "open up" disabled students and get them excited about learning and participating.

Problem: Special education teachers report that they often wish there were more activities focused on children with disabilities.

Aim: Investigate and develop new educational activities appropriate for children with disabilities. This may include mechanical and/or computer software solutions that will provide interactive access for these learners.

Design Criteria: The design must be appropriate for the intellectual and disability level of the students; must be very low cost; safe to use; easy to store, setup, explain, use, and ship; and must fit into the students' educational plan.

Projects for persons recovering from stroke

Standing Straight Project

Problem: Persons recovering from stroke (CVA) often have a significant shift in their perceived center of gravity. This causes them to shift their weight to their unaffected side, with their head and / or trunk at a 20 degree angle, even though they think they are sitting or standing straight. This has a significant negative effect on the tone of their affected limbs, causing them to become more spastic.

Aim: The goal of this project is to develop a dynamic device that would aid the person to realize their true center thus enabling better rehabilitation of their limbs.

Other: A similar device could be used for people recovering from back injury, alerting them when they bend at the back rather than keeping it straight during lifting.

Cellphone and Tablet Holder

Aim: Explore designs for a device that would make it easier to hold and use cellphone and tablets with one hand. This would serve individuals who have had a stroke, who have arthritis, cerebral palsy, or are amputees.

Activities of Daily Living

Aim: Explore designs for devices that would help persons who have had a stroke, who have arthritis, cerebral palsy, have limited arm or hand strength, or are amputees to perform activities of daily living such as cooking, cleaning, or other common household tasks.

Individual Projects

Projects listed in this section are suitable as individual projects rather than team projects.

Students working on an individual project must meet with the course instructor to discuss and agree upon the specifics of the project. Also see Required Course and Individual Project Activities.


General Individual Projects  n

Focus on one of these activities that relates to or would potentially benefit an older adult or individual with a disability:

  1. Research an assistive technology topic - report on new products and research under development.

  2. Pursue a "paper design" of an assistive technology device - develop a CAD design or a "low resolution" physical device built from foam-core or other prototyping material.

  3. Create a work of art - create an original poem, song, skit, painting, or video. (This option would be of particular interest to students who have skills and expertise other than engineering.)

  4. Engage in an aftermarket aesthetic design - select an existing assistive product that could benefit from a better appearance, contact the manufacturer, and work with a user of the device to improve its aesthetic appeal.

  5. Engage in an aftermarket functionality / usability design - select an existing assistive product that could benefit from a better functionality or usability, contact the manufacturer, and work with a user of the device to improve its functionality or usability.

Individual Projects Suggested by the Ideation Workshop Senior User Insights Panel  n

Address concerns expressed by the Ideation Workshop Senior User Insights Panel for the Stanford Center on Longevity's Design Challenge, "Enabling Personal Mobility across the Life Span".

The result of the individual student project efforts should be ideas, concepts, or low-resolution models rather than functional prototypes.

  1. lifting individuals who have fallen in their home (either with or without the assistance of another family member)

  2. promoting community participation through enhanced use of transportation and communication systems

  3. improving appearance and beauty

  4. sustaining mobility and activity after a diagnosis of Parkinson's or other similar conditions

  5. addressing technophobia through instructional techniques

  6. making new friends and maintaining current relationships in the community

  7. redesigning communities for older adults

Specific Individual Projects  n

1. Electric Scooter Design Concept Project

Aim: Explore a CAD design or a low-resolution prototype of a three or four wheeled electric scooter which is fun to use and aesthetically appealing for people who need mobility help and don't want the standard stuff that looks institutional, medical, etc. A commercial product based on the design must be reasonably priced - less than $2000.

2. Fix Adapted Walker for a User Recovering from Stroke

Background: An design that permitted a user with a weakness on one side of his body to more easily steer and push his walker was built in the Spring Quarter of ME113 in 2014. Here is the project description.

Aim: Explore solutions to fix the adaptation - the center handle no longer fits securely in the frame, possibly as a result of wear.


3. Accessibility Survey

Aim: Perform an accessibility survey and analysis of a new Stanford building. (This project might best be accomplished by two students performing surveys of two buildings - one doing the measuring, the other recording and swapping roles between buildings.)


4. Customize the Cane

Aim: Explore ways to add a personal aesthetic to a cane


5. Emergency Response  n

Aim: Explore design concepts to facilitate the protection, detection, and evacuation of people with disabilities and older adults during and subsequent to an emergency event such as an earthquake, flood, fire, or power outage
