This is the year of 2022 AD, which is the year of 3 after COVID, is the universe meta enough? The memory of COVID is still fresh, while the impact of COVID is fading out from our life. When we look back to the past 3 years, nothing has really changed, except remote meeting becomes…
I have been playing with the first audio sunglasses from Bose, Bose Frames. With two speakers integrated separately into the temples sitting in front of the ears, Bose Frames beam music right into your ears and provide open-air audio experience with nothing in or on the ears. One of the reasons I wanted to play…
I have been working on a platform combined with HTC Vive and pressure-sensing technologies to assess human balance in the walking paradigm. With the two new Vive trackers, we can now track foot position and orientation. Vive base stations can track the Vive trackers, so the setup only requires two Vive trackers mounted on the…
I recently took a look into the MultipeerConnectivity framework by Apple when I worked on an iPhone-based AR project. The MultipeerConnectivity framework is a lot easier for Apple’s ARkit to create a multiuser AR experience. Unlike conventional connections, the MultipeerConnectivity does not have to assign hosts or guests if you would like to define all…
When the countdown run from 10 to 0 and the ball dropped in Time Square, we had to wave goodbye to 2019 and to all the happiness and sadness that came along with it. In the meantime, our new journey irreversibly boarded on the ship of 2020 which has just been christened by its champagne…
Some people wanted to Disable Guardian on the Oculus Quest (thanks to Mike for sharing the helpful instruction). A lot of them might have the requirement for obtaining the guardian boundary in their apps. In this blog, I am going to share the method to obtain and visualize the guardian boundaries in your Unity app.…
I have been playing with Pytorch recently and found out that Pytorch is a much easier tool for me to start a machine learning project than Tensorflow. Pytorch uses a different design with Tensorflow and does not need to setup sessions or placeholders, so I feel the setup of Pytorch models is more intuitive. Pytorch’s…
This week I setup a 15-meter walkway in the lab for the obstacle experiment in walking paradigm. I chose to use Vive pro with a wireless adapter to accomplish a wireless VR experience. Compared with Oculus Quest, the wireless Vive pro is much heavier, and it is still constrained by the coverage of Lighthouses and…
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…
