This self-support system allows sick or seriously disabled persons to operate electronic equipment and nursing equipment by themselves, by conveying their needs through a computer synthesized voice. A nurse is not needed. The user need only look at the menu on the screen and blink his/her eyes (or stare for several seconds).

System name(s): TE-9100 Nursing System for Enhancing Patients' Self-support

Who can use the system
Target users ALS patients or those with muscular dystrophy. Elderly disabled persons. Disabled persons requiring a nurse in constant attendance.
What is required from the user Able to focus eyes on the screen. User must be able to blink eyes while staring at the screen. User must be able to understand the menu on the screen.
Can the system be operated entirely by the user without assistance once the system is setup and running?
Applications within AAC
  • Keyboard substitute (gaze writing)
  • Support for book reading (turn pages etc.)
Additional information/accessories This system is mainly sold in Japan. As Japan's regulation of subsidy for disabled peoples is only for "COMMUNICATION AID", this system still supports for their communication. However, the realization of these above functions are problems only on the development of application software, not on the technology of detecting the user's eyegazing points. If European demands these function on the system, we can realize them so easy.

Does the eye tracker require manufacturer's own dedicated software to operate, or can it be used with other suitable software? Only with dedicated software by manufacturer.
If the eye tracker can be used with other suitable software, will the manufacturer make the required control protocols available? Yes, to all.
Does the manufacturer's own dedicated software have an API (programming interface) to allow control over the manufacturer's software and eye tracker by third party applications? Yes.
If the manufacturer's own dedicated software and eye tracker has an API, will the manufacturer make the required control protocols available? Yes, to all.
Is a stream of gaze data (x, y, pupil size, blink etc) from the manufacturer's own dedicated software accessible to other third party software? Yes, can be accessed in real time by third party software.
If a stream of gaze data is accessible in real time, will the manufacturer make the format available? Yes, to all.
Can gaze data (x, y, pupil size, blink etc) from the manufacturer's own dedicated software be captured and saved in a file for later use and analysis? Yes, can be saved.
If gaze data can be captured and saved, is the saved data file accessible to third party software? Yes open, to all in a standard file format.
