Abstract
The size of information spaces often exceeds the limits of even the largest displays. This makes navigating such spaces through on-screen interactions demanding. However, if users imagine the information space extending in a plane beyond the display's boundaries, they might be able to use the space beyond the display for input. This paper investigates Off-Limits, an interaction concept extending the input space of a large display into the space beyond the screen through the use of mid-air pointing. We develop and evaluate the concept through three empirical studies in one-dimensional space: First, we explore benefits and limitations of off-screen pointing compared to touch interaction and mid-air on-screen pointing; next, we assess users' accuracy in off-screen pointing to model the distance-to-screen vs. accuracy trade-off; and finally, we show how Off-Limits is further improved by applying that model to the naïve approach. Overall, we found that the final Off-Limits concept provides significant performance benefits over onscreen and touch pointing conditions.
