Previous works in modeling of curves and surfaces in augmented reality (AR) space has used expensive sensors such as magnetic sensors. In this work, we propose an augmented reality system where a user can model interesting surfaces with her hands, and without expensive sensing systems. The system uses computer vision based methods for the tracking of the user’s head and hand position. Using a g...

This paper presents Hermes, a hands-free authentication system that makes use of credentials stored on a users smartphone to authenticate them when they enter a physical space or the vicinity of a physical object. By combining Bluetooth LE and Kerberos, Hermes is a novel system that makes use of existing technology available in today’s internet-connected devices. This makes a system like Hermes...

In recent years, there has been an increased interest in pain neuroscience education (PNE) in physical therapy. There is growing evidence for the efficacy of PNE to decrease pain, disability, fear-avoidance, pain catastrophization, limited movement, and health care utilization in people struggling with pain. PNE teaches people in pain more about the biology and physiology of their pain experien...

Alphanumeric text entry is a challenge for Virtual Reality (VR) applications. VR enables new capabilities, impossible in the real world, such as an unobstructed view of the keyboard, without occlusion by the user’s physical hands. Several hand representations have been proposed for typing in VR on standard physical keyboards. However, to date, these hand representations have not been compared r...

In this paper, we present a new task that investigates how people interact with and make judgments about towers of blocks. In Experiment 1, participants in the lab solved a series of problems in which they had to re-configure three blocks from an initial to a final configuration. We recorded whether they used one hand or two hands to do so. In Experiment 2, we asked participants online to judge...

FlexM is a flexible physical interface for manipulating and building 3D geometry. The control of modeling with the computer is in the designer’s hands using the FlexM components of hubs and struts. Instead of using the standard mouse interface, the designer builds the model with the FlexM hubs and struts. With the flexible joints on the hubs, the user can sculpt models that transform into a dyn...
