The Human Engineering Research Laboratories at the University of Pittsburgh are adapting fitness-tracking and weighing technologies for people who are physically disabled or have limited mobility due to obesity. The fitness trackers and scales gives people bound in wheelchairs the chance to use this new technology for weight-loss purposes they might not previously had access to.
The institute of higher learning is currently developing a system for affordable assistive scales to help the mobility impaired with their weight management. A set of four discs are placed underneath the user's bed and sync to their smartphone. This weighing technology is presently the subject of a clinical trial and is expected to retail for around $200 USD.
