Modelling Touchless Interaction for People with Special Needs

Touchless interaction has recently been gaining more and more attention through affordable input devices like Microsoft Kinect or Leap Motion. Touchless interaction is also attractive to people with impairments, however, few applications using touchless interaction have been made available to this target group so far. Usually, people with special needs receive individually configured software by their consultants which can be challenging because in many cases the performance regarding interaction with the system varies drastically, even from day to day. It is thus a valid objective to introduce a user modelling approach that can ultimately replace part of consultants' time-consuming configuration tasks. This has partly been successfully implemented in the past regarding conventional and touch-based interaction. This paper presents a prototypic application for modelling touchless interaction capabilities of people with special needs and reports the results of an initial study.
