Abstract

Usability evaluations collect subjective and objective measures. Examples of the latter are time to complete a task. The paper describes use cases of a log analyser for haptic feedback. The log analyser reads a log file and extracts information such as time of each practice and assessment session, analyses whether the user goes off curve and measures the force applied. A study case using the analyser is performed using a PHANToM haptic learning environment application that is used to teach young visually impaired students the subject of polynomials. The paper answers six questions to illustrate further use cases of the log analyser.
