This project enables handicapped users (unable to use a conventional keyboard) to surf the web with a binary input signal. Similar interfaces are called switch interfaces. If a user has a red and a green button, he or she can navigate to the links he/she wants by performing a series of button presses. All links are framed either red or green.
Advantages of Nessi over conventional switch interfaces are:
- Error correction, i.e. the input signal does not have to be 100% correct
- Optimised link selection through a binary tree (faster than TAB navigation)
Nessi is being used by ALS patients who have lost the ability to use a normal keyboard because of paralysis. In this case, the switch interface to Nessi is a Brain-Computer Interface (BCI).
If you are interested in using Nessi, please contact me. My address is: "bensch" then AT then informatik.uni-tuebingen.de.
