A few weeks earlier, I talked about two papers I read regarding gait balance when fixed or suddenly appeared obstacles are involved. The papers are Age Effects on Strategies Used to Avoid Obstacles, and Anxiety-mediated gait adaptations reduce errors of obstacle negotiation among younger and older adults: Implications for fall risk. We have been looking for protocols and…
On Oct 25, we are going to present a poster in a research showcase organized by The Center of Health and Rehabilitation Research (CoHRR). The CoHRR provides opportunities for networking and discussion in all kinds of research fields related to physical rehabilitation. The project we are going to present is our foot analysis system. The…
Our balance assessment research is currently at the point of transforming from a stationary standing paradigm into the dynamic walking paradigm. In the standing paradigm, we explored the assessment of anxiety-caused imbalance through various intensity levels of sound and visual flow. However, the dynamic and stationary paradigms are so different that we cannot use the…
There was a previous blog I wrote about Tobii eye tracking system embedded with HTC Vive. A few friends who are interested in it asked me about my experience with the eye tracking system, so I feel it is good to talk a bit more about it in this blog. There are currently two SDKs…
Recently, I had a chance to test the new released HTC Vive Pro Eye headset. The headset is the first VR headset integrated eye tracking, and it is hard to notice the hardware for eye tracking when compared with a regular HTC Vive Pro. Vive Pro integrated the eye-tracking technology from Tobii, which is a…
I went to Siggraph 2019 a few weeks ago and had some thoughts about VR. With the release of the various commercial VR systems from the technology giants, VR is no longer a mystery these days. More and more people in all kinds of fields began to see it as a profound tool rather than…
This post is to share the solution of a problem that happened during the development with Oculus Quest. I got the solution from Connor (he was a colleague who has a lot of experience on Quest and just graduated in the summer). I have been working on a Unity project which requires to record position…
Earlier this year, our lab got a lightweight IMU-based wearable motion capture system called Notch. The system is a set of six waterproof IMU sensors designed to be mounted on the body. The motion capture system does not use external cameras like Optitrack or Vicon which uses a group of infrared cameras to triangulate the…
Rokoko motion capture suit is an IMU-based motion capture system with IMU sensors worn on the human body and recovers poses from measuring orientation and acceleration of each IMU sensor. The suit tracks all the major body components except fingers with 19 IMUs. Last week, Ben, Connor and I made a demo video showing how…
I am sure most of you have seen Ken’s Chalktalk demos. In one of his demos, he uses a green object attached to a pen as the drawing tool. It would be nice to use bare hands as the tool for interaction, so we implemented this simple hand tracking component for Chalktalk. It uses the…
