Specifying and Characterizing Tactile Performances for Multi-Touch Panels: Toward a User-Centric Metrology

Whereas Vision Human Factor (VHF) studies provide an abundant literature to characterize display modules, building a specification for touch sensitive systems - and more noticeably for multi-touch capable ones - remains substantially empirical. Existing metrology gives useful data with regards to the mechanical and optical performances of touch panels. However, it fails to measure what import the most to the user: tactile performances. With the fast-growing market demand for Multi-Touch panels emerges a need for a user-centric metrology to objectively evaluate the usability of available solutions.
