Abstract: “This study examines an objective measure for discriminating between different degrees of performance in a child’s use of multiple non-hand-held devices when undertaking a simple competence test: the maximum streak of successfully, making a binary (YES / NO) response in the test. The paper reports encouraging results for the maximum consecutive success (streak) measure in its ability to inform on device suitability for a particular child. Our results show that different devices influence success streak, while performance of children vary when using different devices, based on severity of impairment. While this is in line with our main hypothesis, that a suitable match between device and impairment is necessary, our results provide a first candidate measure that can be potentially useful to personalizing a device to a particular user and his/her capabilities.”
