The team identified the following list of initial, overall constraints:
- Compiling to ergonomic standards – anthropometric data
- Stay within current size envelope of mobility device
- Device needs to be portable
- Invoke feeling of safety and security
- Cognitive ability of older adults
- Limited fine motor skills and grip strength of older adults
- Device needs to be simplistic and intuitive for older adults to use easily
- Legal issues i.e. the device might help user but if it hinders ability to move it is “restraining”
- Medical regulations and funding
