While both touch detection and hand tracking can be independently useful for achieving interaction with tabletop displays, these techniques are not reliable when multiple users in close proximity simultaneously interact with the display. To solve this problem, we combine touch detection and hand tracking techniques in order to allow multiple users to simultaneously interact with the display without interference. Our hope is that by considering activities occurring on and above a tabletop display, multiuser interaction will become more natural and useful, which should ultimately support collaborative work. 1. Introduction Large displays are useful for information visualization when multiple people must jointly use the information to work together and accomplish a single goal. The social interactions that result from using a shared display can be highly valuable [1]. However, these displays can fail to allow multiple users to simultaneously interact with the information. Tabletop interfaces can provide a large shared display while simultaneously accepting natural and direct interaction from multiple users through touch detection. For example, multi-touch surfaces that utilize the phenomenon of frustrated total internal reflection (FTIR) have received widespread attention recently [2]. FTIR detection techniques allow the system to track a large number of simultaneous touch points with very high spatial and temporal frequency. The FTIR has several advantages over other multi-touch detection technologies,
