Camping Cot Project

Background: "I love the freedom I feel when I go camping."

Problem: "My Therm-a-Rest camping cot sits low to the ground (6 inches). The bed material and the long poles across the cot's width are not a problem. However, it takes a lot of force and hand strength to attach and remove the legs. Even an able-bodied camper had difficulty putting a leg on, so I didn't use it on a recent camping trip. It is a great cot, just much too difficult to assemble and disassemble."

"There are 2 collapsible rods that slide into sleeves down both sides of the cot. The legs are too difficult to bend into the right position and hook into openings along the sleeves around the rods. If the legs were integrated into the cot or if there was an easy way to attach and remove its legs - that would be ideal."

"I have tried other cots from both REI and Sports Basement and have not found one that I could put together by myself. The Helinox cot is very heavy, and very expensive."

"I read a review of Big Agnes Helinox Cot Lite where it was described as needing a lot of hand strength/force to put it together - 'note that adult strength is required for assembly and disassembly'."

"Amazon offers many cots, but unless you actually buy one and try putting it together, you have no idea if it is in fact light and easy to put together."

Aim: Explore designs for a camping cot that Abby will find to be easy to assemble and disassemble independently.

Design Criteria:

  • "I am interested in a cot that sits low-to-the-ground."
  • Easy to assemble and disassemble independently
  • Lightweight and portable (parts are collapsible and fit into a small sack)

Laptray Project

Background: "One project I would like to suggest for your class next year is a tray."

Problem: A wheelchair user's lap is not always an ideal surface as it is not flat, so items may fall off during travel and the lap may not be at a comfortable height for other tasks.

Aim: Explore designs for a wheelchair accessory that will aid Abby in performing common tasks. Anticipated laptray uses include: a drawing / writing / work surface, a support for a laptop, and a platform for eating.

Design Criteria:

  • Fits between arms of Abby's WHILL wheelchair
  • Is lightweight and portable
  • Collapses to fit in Abby's backpack
  • Will not slide off her lap

Alert Project

Background: "Another project I am interested in is some kind of an audible alert that I could easily press to alert people that I am passing. I had this idea for Project Invent this summer, and the idea one team was working on was a recording of my voice very loud saying "Passing By," "Coming Through," or "Excuse Me." My idea is that it would attach to the right arm of the WHILL so that I would have easy access to press on it. I have looked at bicycle bells, horns, etc. The problem I have is using both hands with Nathan and the WHILL, and not being able to hold something else. Bicycle bells are for rounded handlebars, and don't fit the WHILL arm, plus you have to turn them, press something small on them, or some other way of getting the noise that I can't do. The noise has to be loud enough for people to hear it."

Problem: In crowded spaces, people are not often aware of a wheelchair user trying to negotiate the "walking traffic", increasing the possibility of collisions.

"This is a huge problem everywhere I go outside in the community, or in buildings. Many times an individual's attention is not on where they are walking, or how their walking patterns may affect someone coming from behind in a powered wheelchair."

Aim: Explore designs to alert people in Abby's path.

Design Criteria:

  • Easy access to activation mechanism on right side of wheelchair
  • Easy activation while operating wheelchair and controlling Nathan
  • Loud enough for people to be alerted in noisy rooms
  • Several alert modes and volumes

TravelScoot Camping Project

Background: "I go camping with my TravelScoot. Its front-mounted Foldable Shopping Basket is of wire-frame construction and enables me to hold and transport water bottles and lunches for Nathan and me."

Problem: "The basket does not attach to the scooter very well and it is not very stable."

Aim: Explore designs for an improved device for transporting camping items.

Design Criteria:

  • Easy to attach and remove from the scooter
  • Stable when moving around the camp site
  • Foldable for stowing in a car

Other: "I have the Junior Deluxe model of the TravelScoot. Because it is narrower in the back, it does not accommodate the company's rear-mounted basket accessory."

WHILL Model Ci Enhanced Visibility Project

Background: "The WHILL Model Ci power wheelchair has no lights so it is unable to illuminate my path for early morning or late afternoon activities such as walking my dog Nathan or going out at night. This is a real problem when you consider where there are van accessible parking spaces and locations of activities. A movie and restaurant outing may include parking in one place, and meeting friends in a location a block or so away. Lighting is not always available in parking lots, and many times parking lots are located in back of buildings. Adequate lighting means the difference between safe maneuvering both for me and Nathan wherever I want to go."

Problem: Abby's new wheelchair has no lighting which creates a safety hazard while walking Nathan in the early morning or traveling at night.

Aim: Explore ways to enhance the night time visibility of Abby's wheelchair

Design Criteria:

  • Must provide both forward illumination and side visibility
  • Must be easy to attach and remove

Within Reach Project

Problem: June increasingly finds that items in her upper kitchen and closet shelves are now out of her reach. 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:

  • integrate onto her walker
  • be easily installed onto and removed from her walker
  • be able to be fitted to a variety of walker products
  • be easily deployed for stepping and retracted when not being used

The stepping area must:

  • offer a sense of security during use
  • have a wide, non-slip surface
  • provide the proper height advantage

Other: Visits to June's home in San Francisco will be required. June has an extra walker to donate to this project.

Magical Bridge Playground

Background: The Magical Bridge Playground is the nation's first fully accessible and socially inclusive playground. It is a public space where children with disabilities as well as children of parents who have a disability can play together. The City of Palo Alto 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 - adjacent to Abilities United and close to the new Mitchell Park Library.

The playground opened in April 2015 and has been overwhelmingly popular with both kids and parents, with some families traveling long distances to experience it.

After the Playground was completed, the Magical Bridge Foundation was created to assist other communities in building their own innovative and inclusive playgrounds. Construction on a Playground in Redwood City began in the Fall of 2017, and funds are currently being raised for Magical Bridge Playgrounds in Sunnyvale and Morgan Hill.

Accessible and Inclusive Playground Attractions

Problem: The park's play equipment has been well-received, but some aspects of the play areas could be modified for better access. In addition, suggestions for replacement play areas are sought to update the park with fresh attractions every few years. And as new Playgrounds are planned and constructed, there are ongoing opportunities to design new features and refine existing designs to be accessible to everyone regardless of their abilities.

Aim: Explore designs to improve access to and navigation around the playground, as well as to create new play and educational experiences incorporating multiple senses, actions, and outcomes for all playground users and visitors, especially those with visual impairments and diminished fine motor skills.

Design Criteria:

  • Designs should be durable, fun, and safe for everyone - accommodating children and parents with disabilities - and be magical.
  • Project prototypes could be scale models to facilitate their construction and transportation.
  • Designs that incorporate electronics should be low-voltage or solar-powered.

Wheelchair Dancing

Background: There is considerable medical support documenting the positive health benefits of dance and movement for people experiencing stress-related physical and psychological symptoms, pain, depression, cardiovascular disease, dementia, Parkinson's disease, diabetes, cancer, and other conditions - promoting emotional, social, cognitive, and physical well-being, as well as an enhanced quality of life. Movement / Dance classes are offered at many Senior Centers.

Problem: Individuals who use wheelchair are unable to "dance" in the traditional sense and some older adults who don't use wheelchairs may experience balance issues that may affect their ability to stand, walk, or move safely. However, with encouragement, they can all engage in dance while seated through movement of the body parts they can control: head, neck, arms, hands, torso, and feet.

Aim: Explore designs to provide encouragement and enhance the dance experience for both wheelchair users and individuals who can not stand for long periods.

Design Criteria:

  • the design should not permanently alter the user's chair or wheelchair
  • the design should be portable
  • the design may be battery-powered
  • the design may provide encouragement and attention in multiple ways

Designing Your Afterlife

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

Problem: With one's passing, it is impossible to provide a full and accurate representation of whom 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.
