Real time groupware systems often display telepointers (multiple cursors) of all participants in the shared visual workspace. Through the simple mechanism of telepointers, participants can communicate their location, movement, and probable focus of attention within the document, and can gesture over the shared view. Yet telepointers can be improved. First,(More)
Fisheye views use distortion to provide both local detail and global context in a single continuous view. However, the distorted presentation can make it more difficult to interact with the data; it is therefore not clear whether fisheye views are good choices for interactive tasks. To investigate this question, we tested the effects of magnification and(More)
Desktop conferencing systems are now moving away from strict view-sharing and towards relaxed " what-you-see-is-what-I-see " (relaxed-WYSIWIS) interfaces, where distributed participants in a real time session can view different parts of a shared visual workspace. As with strict view-sharing, people using relaxed-WYSIWIS require a sense of workspace(More)
Real-time desktop conferencing systems are multiuser computer applications that allow physically distant people to work together in a shared virtual space at the same time. These systems do not yet provide the rich communication and awareness that are possible in a face-to-face interaction. One of the elements lacking in desktop conferencing is group(More)
A female advantage has previously been found for spatial location tests of object memory. Previous studies have used static, 2-D tasks to test this advantage. This study used a computerized adaptation of the game Concentration to test object location memory in both a static and dynamic array of 24 pairs of line drawings. The dynamic version of this task was(More)
Electronic health records (EHRs) are now being adopted in many regions, in part due to their promise of supporting information sharing between distributed health care workers. This technology allows an implicit form of collaboration by providing information about treatments and outcomes among the individuals involved in the patient's care. However, it is(More)
Neurologically normal individuals show a bias toward the left side of space, referred to as pseudoneglect due to its similarity to clinical hemispatial neglect. The left bias appears to be stronger in the lower visual field during free-viewing, which could result from preferential dorsal stream processing. The current experiments used modified greyscales(More)
Digital tabletop systems are currently receiving considerable attention, but present systems do not allow the fluid and natural work that is evident when people work around a traditional table. This fluidity is particularly obvious in highly-integrated collaboration, where people work together in a closely coordinated fashion. Highly-integrated(More)
