ABSTRACT
We attached a small LCD display and video camera to a surgical drill. The LCD shows the tool position with respect to a planned trajectory, overlaid on video captured by the camera. We performed a user study to determine whether such a tool-mounted guidance display yields faster and more accurate tool placement than the conventional guidance display on a separate computer monitor. Our study showed that the tool-mounted display provides better positional and angular accuracy than the conventional display but that the video camera provides no significant improvement in error.

Design and evaluation of a layered handheld 3d display with touch-sensitive front and back
NordiCHI '14: Proceedings of the 8th Nordic Conference on Human-Computer Interaction: Fun, Fast, FoundationalTouch screens became truly pervasive through the success of smartphones and tablet PCs. Several approaches to further improve the interaction with touch screens have been proposed. In this paper we combine and extend two of these trends. We present a ...
Can a Helmet-mounted Display Make Motorcycling Safer?
IUI '18: Proceedings of the 23rd International Conference on Intelligent User InterfacesIn this paper we investigate whether a helmet-mounted display for motorcyclists can provide similar benefits as the established head-up display (HUD) in cars. HUDs can increase driving safety by efficiently informing the driver. Given their high safety ...
Nail-mounted tactile display for boundary/texture augmentation
ACE '07: Proceedings of the international conference on Advances in computer entertainment technologyWe developed a device that can superimpose tactile information onto an object displayed on a computer monitor. With this device, we can present tactile sensations of boundaries or textures corresponding to the visual image. The device is composed of a ...
