Human-computer interface, eye tracking and control
Individuals with severe disabilities are very dependant
upon carers, even for the simplest of everyday acts.
However, suitable assistive technology can give such
individuals improved independence. The ability to control
environmental and other ICT devices in the home is an
important factor for individuals with severe movement
impairments and the development of an eye-operated
control system for such individuals is described. This
allows an individual firstly to identify a device and then
choose to operate it primarily by using their eye gaze. A
user focussed approach was used by first identifying what
devices a user with restricted mobility would want to
operate as well as involving potential users, carers and
associated professionals through the development process.
Whilst such a system does not represent the best
interactive approach for all users in all situations it does
represent an important and useful option for individuals
with movement restrictions.
