Researchers at the Massachusetts Institute of Technology have designed a “smart sports mattress” that uses motion sensors to accurately track 97% of sports movements. This technology can be used in games, exercise and preventing the elderly from falling.
During this week’s Computer and Pattern Recognition Conference, a team of researchers at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) unveiled a mattress measuring about 11 by 0.5 meters that can be used in a variety of user positions, including sitting. Stand and track in motion with a three-dimensional model. If someone is sitting on a mattress, the system can take a picture of sitting. Due to the dimensions of this mattress and the price for it, it can be used for home use in the near future.
Made of very thin sheets sensitive to pressure and conductive yarn, the mattress has more than 9,000 sensors that detect pressure on the feet, pelvis and other organs and convert it into an electronic signal. In experiments, the system was able to predict the movement of volunteers with 97% accuracy and determine their position in an error of less than 10 cm.
The research team of this project has used the cameras only for the initial training of the smart mattress and then all the activities are determined and performed based on the neural network of this system. According to the researchers, the mattress is better at determining the movements of the lower body and is not able to predict movements that do not touch the ground.
“Yunzhou Li,” a leading researcher in the system and a MIT PhD student, said:
“Only on tactile information can the system detect activity, count the number of repetitions and calculate the amount of calories burned.”
Researchers hope to improve the system to determine more accurate information, including height and weight, and to produce synchronous metrics for multiple users (such as while dancing).
