View changes in augmented reality computer-aided-drawing
Do Hyoung Shin, Phillip S. Dunston, Xiangyu Wang
Pages: 1-14
DOI: 10.1145/1048687.1048688
A prototype augmented reality computer-aided-drawing (AR CAD) prototype aimed at supporting a design detailing and review process has been developed. Utilizing head-mounted displays, AR CAD supports users in manipulating design models with two...

A study of level-of-detail in haptic rendering
Shahram Payandeh, John Dill, Jian Zhang
Pages: 15-34
DOI: 10.1145/1048687.1048689
This paper presents an initial study of an approach to reduce computational overhead in haptic rendering of physically based models. Haptic rendering refers to the notion of adding physical properties and behavior, specifically a sense of touch or...

Throwing versus walking as indicators of distance perception in similar real and virtual environments
Cynthia S. Sahm, Sarah H. Creem-Regehr, William B. Thompson, Peter Willemsen
Pages: 35-45
DOI: 10.1145/1048687.1048690
For humans to effectively interact with their environment, it is important for the visual system to determine the absolute size and distance of objects. Previous experiments performed in full-cue, real-world environments have demonstrated that blind...

Enhancing haptic detection of surface undulation
Ryo Kikuuwe, Akihito Sano, Hiromi Mochiyama, Naoyuki Takesue, Hideo Fujimoto
Pages: 46-67
DOI: 10.1145/1048687.1048691
This paper introduces a device for enhancing detection of surface undulation through active touch. This device, which we call a “tactile contact lens,” is composed of a sheet and numerous pins arranged on one side of the sheet....
