The limitations of stereo display systems affect depth perception, e.g., due to the vergence-accommodation conflict or diplopia. We performed three studies to understand how stereo display deficiencies impact 3D pointing for targets in front of a screen ...

We present a study comparing selection performance between three eye/head interaction techniques using the recently released FOVE head-mounted display (HMD). The FOVE offers an integrated eye tracker, which we use as an alternative to potentially ...

When working on a task, mobile device users want to complete their work as quickly and efficiently as possible. In order to accomplish this they must use the navigational tools available on the system's interface. The importance of control design to ...

In this paper we present a comparative study of free-hand pointing, an absolute remote pointing device. Unimanual and bimanual interaction were tested as well as the static reference system (spatial coordinates are fixed in the space in front of the TV) ...

Fitts's Law has been used extensively in HCI to describe 2D targeting; however, the controlled tasks generally used neglect aspects of real-world pointing, including how the intended use of a target affects its acquisition. We studied aiming to a target ...

The widely-held view that Fitts' law expresses a speed/accuracy trade-off is presumably correct, but it is vague. We outline a simple resource-allocation theory of Fitts' law in which movement time and error trade for each other. The theory accounts ...

Several enhanced pointing techniques aim to reduce the Fitts' law targeting distance by providing multiple target trajectories in the hope that a shorter path is available. However, these techniques introduce a search or decision component to pointing ...
