Since we began designing and building multitouch tables more than a decade ago, we have continually referred to ADA and ETSI standards for accessibility. These guidelines have been tremendously important in helping exhibit developers maximize the accessibility of the experiences they create. However, neither set of guidelines directly address touch tables or large displays, so digital designers have always needed to devote some time to interpreting the guidelines for these form factors. Now, we’ve decided to take a much deeper look and attempt to lay out a more standardized approach to accessibility for touch tables and interactive displays.
Our latest white paper, Accessible Design for Multitouch Tables, Large Displays, and Interactive Experiences focuses primarily on access for individuals in wheelchairs or those of short stature who may have reach, roll-up, or related mobility limitations. Building upon existing standards, this paper presents both “broad” and “strict” interpretations for accessible design on multitouch tables and describes a range of approaches for incorporating them into new experiences.
