Communication appliances, intended for home settings, require intuitive forms of interaction. Computer vision offers a potential solution, but is not yet sufficiently accurate.As interaction designers, we need to know more than the absolute accuracy of such techniques: we must also be able to compare how they will work in our design settings, especially if we allow users to collaborate in the interpretation of their actions. We conducted a 2x4 within-subjects experiment to compare two interaction techniques based on computer vision: motion sensing, with EyeToy®-like feedback, and object tracking. Both techniques were 100% accurate with 2 or 5 choices. With 21 choices, object-tracking had significantly fewer errors and took less time for an accurate selection. Participants' subjective preferences were divided equally between the two techniques. This study compares these techniques as they would be used in real-world applications, with integrated user feedback, allowing interface designers to choose the one that best suits the specific user requirements for their particular application.
