Tactile and haptic interaction is becoming increasingly important; ergonomic standards can ensure that systems are designed with sufficient concern for ergonomics and interoperability. ISO (through working group TC159/SC4/WG9) is developing international standards in this subject area, dual-tracked as both ISO and CEN standards. A framework and guidelines for tactile/haptic interactions have recently been published as ISO 9241-910 and ISO 9241-920 respectively. We describe the main concepts and definitions in support of a new standard that describes how to evaluate tactile/haptic interactions and how to link this evaluation to previous standards. The new standard addresses three major aspects of the evaluation of a tactile/haptic system ̶ the validation of system requirements, the verification that the system meets the requirements, and the overall usability of the system. Several measurement and analysis techniques are discussed, such as the calculation of scores for the determination of effectiveness. Tactile/haptic measurements have to be repeatable, and as an example we discuss how an appropriate model of the interaction with a virtual wall can be formed and used in evaluating a device.
