Camera for K is a photographic interface for disabled people who use wheelchair and cannot operate digital cameras.


Camera for K is a photographic interface that maximizes independency of physically handicapped people who use wheelchair and cannot operate the interface of normal cameras. Any switches familiar to them can be attached to this interface so that they easily start to use.

Moreover, the system is designed to meet adaptibility, available not only to a specific client, as well as sustainability, easy to maintenence and easy to bulid the same one.

This system is basically designed for handicapped people who have a cerebral palsy with athetoid movements and show dyskinetic, jerky movements or very low power mobility.

Design Objectives

1. Maxmizing Independency

- Steps of photography: Divide and analyze the steps so that make it possible to operate a camera by themselves

- Mobility: without connection to computer

- Delay time: Put 2 seconds delay time between pressing the button and releasing the shutter in order to avoid unwanted shaking

2. Adaptibility

- Standard switch sockect: Any kind of switches generally used by disabled people can be attached

- Bendable tripod: By using bendable tripod, this system can be attached to any type of mount

3. Sustainability

- Easy to maintenance: minimize electronic parts

- Purchasable parts: All parts are purchasable through the Internet. So easy to build the same system

Personal Statement

When I visited the Henry Viscardi School for disabilities in Long Island, I met a high school boy who was using an electric power wheelchair, had a speech impairment and showed cerebral palsy with athetoid movements. In spite of these disabilities, he had a passion of photography. He brought me to the computer and typed a "digital camera" on the internet image search engine to show me images of digital cameras. He was extremely excited whenever he heard words related to photography such as flash, album, year book, Canon and Sony. If I make a camera interface for him, he will have a chance to be a professional photographer or, at least, will have a good hobby for his life.

Background: Maximizing independency is the one of the most important keys of assistive technology. There is a need to operate existing electronic objects such as digital camera to express creativity, however, the interface is impossible to operate for most disabled people. Since each person is already using specific body parts to operate particular switches, it will be a good way to use their familiar interface to attach the new system.

User Testing

I've had user testing three times, and the feedbacks have changed and polished the design.

- Tested by six students who have different disabilities. But, the system could be attached to any mount they had, the switches already familiar with them also could be used.

- The system is easy to start using by all.

- One of students moved both hands simultanesouly to make a posture that is hard to them and takes 6 months time period to teach.

- They learned photographic skills such as framing, adjust size of objects and keep calm after releasing the shutter

- It also hard to teach them to keep calm after a single movement, but students did it so for better quality pictures.
