Design and evaluation of Multi-function Scanning System : a case study

We present in this paper an assistive technology of communication and command for quadriplegics. To carry out this assistive technology, a user centered design approach with the patient, his occupational therapists and his family was conducted. Various iterative versions of the prototype have been defined by means of the SOKEYTO platform to meet the needs and the abilities of the quadriplegic person. Options carried out and consecutive choice will be reported as well the difficulties to implement. The assistive technology was used by one quadriplegic person. A qualitative evaluation is also reported.

Transforming medico-educators into design partners to build HMK, a mathematical input keyboard for second graders

Children with severe motor disabilities experience motor fatigue when inputting mathematica formulas with applications such as Open Office or Microsoft Office. To mitigate this feeling we have implemented a user-centred design method for the design of a virtual keyboard for mathematical input called HMK. The objective of this article is to show how mediators of medico-educational can contribute to the design of HMK for college students and high school students with neuro motor handicaps.

HandiMathKey: Mathematical Keyboard for Disabled Person

To type mathematical formula is a tedious task for all of us with the usual applications. Moreover, this task is very tiring for motor impairment. This paper describes the user centred methodology used to design the HandiMathKey virtual keyboard to type more easily the mathematical formula. Then we present a case study that compares the entry time between HandiMathKey and Word office for the mathematic formulas typing. This study shows that the HandiMathkey is easier to use and more efficient.
