After participating 2 rounds of application to the second Annual Innovators in Aging Award, our team (Zhu Wang, Marta Gospodarek and Rufei Sheng, advised by Prof. Ken Perlin and Prof. Anat Lubetzky) finally won the award. The competition, held by NYU Aging Incubator, aims to promote the study of aging and its impacts, and further…
Pressure sensing technologies have the advantage of obtaining the center of pressure. The center of pressure (COP) is defined by measuring the mean position of pressure distribution on the planar surface of the pressure mat. The COP of both feet are not going to be the same when we stand on the pressure mat and…
Balance control is a complicated process, which involves multiple systems such as the vestibular system, motor system. A lot of factors can cause imbalance but the underlying connections between the factors and imbalance are not well researched. We approach to reveal the primary factors and their connections to balance by analyzing the parameters that we…
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…
