Eye typing in application: A comparison of two systems with ALS patients

A variety of eye typing systems has been developed during the last decades. Such systems can provide support for people who lost the ability to communicate, e.g. patients suffering from motor neuron diseases such as amyotrophic lateral sclerosis (ALS). In the current retrospective analysis, two eye typing applications were tested (EyeGaze, GazeTalk) by ALS patients (N = 4) in order to analyze objective performance measures and subjective ratings. An advantage of the EyeGaze system was found for most of the evaluated criteria. The results are discussed in respect of the special target population and in relation to requirements of eye tracking devices.
