New VEMI Research on Guidelines for Nonvisual Graphical Access

VEMI researchers have recently published a new paper providing guidelines and best practices for nonvisual access to graphical material using touchscreen-based haptic interfaces. The article, published in the International Journal of Human-Computer Interaction (IJHCI), synthesizes the results of a series of six studies with both blind and sighted participants evaluating the efficacy of the vibro-audio interface previously developed in VEMI. Results provide a definitive set of empirically-derived parameters for using this interface in an intuitive and perceptually-valid manner and have relevance to any researchers/developers studying and designing touchscreen-based haptics for nonvisual and eyes-free applications.
