Evaluation of Haptic Systems

Abstract

AbstractIn this chapter, a number of measurement methods and tests are presented that can be used either for verification or validation or—sometimes—both. We therefore refrain from an ordering based on this steps, but will present the methods based on the focus of the evaluation method. In that sense one can identify three main foci of evaluation methods: system-centered methods that will test system properties (and are mostly used for verification, Sect. 13.1), task-centered methods that will test the task-performance of a user working with the haptic system (such tests are mainly used for validation but they can also verify system properties depending on the test design, Sect. 13.2) and user-centered methods that will measure the impact of the haptic system on the user. The latter are almost exclusively used for system validation and further described in Sect. 13.3.
