Tactile and haptic interaction is becoming increasingly important both in assistive technologies and in special purpose computing environments. While considerable research exists, the current lack of ergonomic standards in this area results in many systems being developed without sufficient concerns for either ergonomics or interoperability. This leads to serious ergonomic difficulties for users of multiple, incompatible or conflicting tactile/haptic devices/applications. A new set of ISO standards is being developed as a set of new parts of ISO 9241 Ergonomics of Human-System Interaction by a working group of ISO TC159/SC4 (WG9 Tactile and Haptic Interactions). These standards, which are being dual-tracked as both ISO and CEN standards, provide ergonomic requirements and recommendations for haptic and tactile hardware and software interactions, including guidance related to the design and evaluation of hardware, software, and combinations of hardware and software interactions. This paper starts with a short introduction on the background of tactile and haptic perception and devices. Thereafter, we will introduce the work plan for WG9 and the documents that already are, or will be under development in 2006/2007. More details are provided on the guidelines document, including an introduction of the framework that will be used to structure the guidance. The first working draft of this document was developed by experts from 6 countries, and combines guidance from 40 research papers and from 10 ISO standards.
