Distance Effect: Where You Stand Determines How Promptly You Interact with Game

摘要

Interaction efficiency is an important concern in game playing, due to that it reflects the degree of how promptly users respond and dominates user experience. To understand the relationships between interaction efficiency and distance in motion-sensing games, this paper conducted empirical studies to assess user performance (mostly hand gesture movements) at various interaction distances. The results identify the existence of 'low point' at which users responded less efficiently, the range of 'low point' values was much smaller than that of usual distances as we selected though. Beyond that, interaction efficiency recovered quickly to a steadily high level with distance increase. The results implied the distance's direct influence on interaction efficiency in motion-sensing game playing, and it also shows new avenues to address the interaction efficiency in game playing according to standing distances. Furthermore, guidelines were provided to assist game developers to fully consider the role of distance.
