Development of novel haptic tools for virtual navigation
… how to navigate a real space using haptic virtual environments can be challenging. One major issue is the inefficient rate of exploration due to the single point interface of haptic devices. The use of haptic fields such as repulsive and attractive force fields was studied to determine …

Effects of sex, free testosterone, and androgen receptor cag repeat number on spatial cognition and virtual navigation performance
<p>The male advantage typically found on some measures of spatial cognition (e.g., mental rotations) has been approached for three decades from the perspective that androgens contribute to this sex difference. To date, evidence to support the notion that androgens affect spatial cognition in …

A brain-machine interface for investigating neural representations of navigation in a virtual environment
… we investigate the neural representations of navigation in the Posterior Parietal Cortex (PPC) of mice during a virtual navigation task. We recorded neural activity during completion of a T-maze task using 2-photon calcium imaging, and trained decoders to decode task relevant variables from …

Space to Think: Sensemaking and Large, High-Resolution Displays
… can largely be attributed to the replacement of virtual navigation (e.g., panning and zooming) with physical navigation (e.g., moving, turning, glancing). This research moves beyond the question of performance or efficiency and examines ways in which the large, high-resolution display can support …

The role of proximity in human-agent trust
… increasingly operate as social partners in virtual and mixed reality contexts, understanding the mechanisms that foster or erode trust becomes essential for designing effective and reliable human-agent relationships. Building upon theories of social cognition, embodiment, and proxemics, this …

Electromagnetic tracking and steering for catheter navigation
… invasive surgeries. The end application is virtual navigation of the lung for biopsy of early stage cancer nodules. Navigation to the peripheral regions of the lung is difficult due to physical dimensions of the bronchi and current methods have low successes rates for accurate diagnosis. …

Navigating Virtual Environments At Scale
Using real walking for virtual exploration generally delivers most immersive VR experience, however, it is limited by the availability of physical tracking space.Virtual spaces beyond the size of tracked space are inaccessible. Limiting virtual world to match the shape and size of physical space is …
