Recently, I implemented more real-time functions in the foot pressure analysis system including foot width, foot length, foot rotation angle, in addition to the previous features such as the center of pressure, and width of stance, and arch index. The rotated bounding box of the electronic footprints was used to determine the orientation and dimension…
In the beginning, I want to thank all the participants in our arch index study! From the comparison between the footprints and pressure images so far, we noticed that pressure image might not be a good substitution for footprints. Pressure image can intuitively visualize regions with variable pressure as a heatmap. However, it is not…
NYU Aging Incubator announced its second Aging Award competition which aims at encouraging teams to design and develop tools or systems that would enhance research, policy or lifestyle for the older population. We applied to the competition with our VR system for balance. The current VR system we developed for balance training is a VR…
I have been working on Arch Index measurement by utilizing Tactonic pressure-sensing floor mats. Recently I updated my Arch Index software to make the results more similar to the ones obtained by Harris Mat which is the traditional measurement widely used in clinics. Please see https://frl.nyu.edu/everyday-could-be-the-day/ and https://frl.nyu.edu/improved-arch-index-program/ if you are interested in how it…
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…
