The basic idea of the arch index program is to calculate the ratio of the middle third area of a footprint to the whole footprint area. How we obtain and process the foot pressure image directly and severely determines the result. I recently upgraded my arch index program on the image capture module. In the…
I have been developing applications for Pressure-sensing floor mat for the past few years. When comparing to typical motion capture devices, floor mat proved it is irreplaceable on the tasks such as monitoring weight shifting and muscle movement. One piece of the floor mat is only about 2 sqft. People may not be able to…
As mentioned in my last blog, our lab got two Intel Realsense stereo cameras. I got a chance to try one of them for testing. Ken told me he got an idea about multitouch detection by utilizing depth, and we wanted to see if it can work out on the Realsense camera. By pointing down…
First, Happy New Year to everybody and their family. Lately, our lab got two Intel RealSense D415 stereo camera, Alex and I have been testing their volumetric tracking. Comparing to Kinect v2, RealSense D415 has a better field of view, faster FPS, and finer depth resolution. 30 fps of Kinect v2 will not be a…
In my past blogs, I mentioned that I have been working on a project that recognizes footprint image captured by Tactonic pressure sensor, and obtains the Arch Index by calculating the ratio of the middle third area to the whole footprint area. Arch Index is a good way to measure the height of the foot…
When HTC Vive released their ultimate mixed reality (MR) Vive Pro, we were all surprised that a front-facing dual camera is integrated into the headset. Users can see a stereo passthrough video by each eye obtaining a separate image from the stereo camera. Ken told me about one of his idea that is having a…
Since the very first day our lab started to use VR headsets, every single one of us has been imagining that the experience would be much more wonderful if we could have an untethered VR headset someday. In the last quarter of 2018, our dream finally came true. In the past September, HTC announced their…
As many of you know, our lab has collaborations with Physical Therapy and Music Department on a few projects including the VR-based balance rehabilitation project I have been working on. Recently, our work was accepted as a presentation to the NYU Technology Summit (https://www.nyu.edu/life/information-technology/about-nyu-it/key-projects-and-initiatives/nyu-technology-summit.html). The summit aims at showcasing innovative and emerging technologies used in…
I talked about collision avoidance by using Unity NavMesh in my last post. The result is great if you have an agent who needs to avoid all the obstacles no matter when they move or stay stationary. The NavMesh agent module in Unity takes care of the pathfinding, and the obstacle module defines what objects…
Recently I tried Unity’s NavMesh to implement a prototype of collision avoidance module for our physical therapy balance project. Rather than using connected points and graphs to search and represent the optimal path, NavMesh(navigation mesh) defines the walkable space by polygons, and objects can walk through the polygons to reach the waypoints. Currently, in our…
