There are a lot of research work done in using the mobile phone sensors to measure the gait for various purpose.
1) You might want to list out the value of this device compared with existing literature work or commercial product?
2) Will the device be worn all the time to get enough date related to the gait to predict the potential risk of the senior falling before it happens? Or it only needs to be worn when the therapist want to evaluate the senior?
3) It would be great to have a great design that takes in various aspect into consideration. Part of the reason is to avoid seniors feel that wearing such devices it will cause any form of discomfort or stigmatization. The design should increase their dignity in using it, ease of use and increase the value of the solution to stakeholders. During the design stage, it should be validated with the stakeholders to ensure a good product fit.
I look forward to the end product and seeing it make the world a better place for our well-deserved seniors!
I personally think this is a good idea - in a way also to prevent fall. You may want to throw in a few ways of detecting possible emergency when the senior is in trouble. The challenge for any robotic platform will face is the cost, business model and the value the stakeholder receive - the value needs to be clear and worth a few times over its cost. Keep up the good work and I look forward seeing this product from imagination to reality.
Great idea of using carpet to prevent fall and detecting fall. A few key challenges:
1) How big is the carpet? Will need how many carpets to ensure we cover enough areas. How to power each carpet inside the house. Using battery may required maintenance.
2) As with the use of any technology there will be false alarms - which I think everyone will have to embrace this fact. Welfare organizations that I've spoken that embrace technology to monitor seniors living alone faces the challenge of verifying the alerts they receive. It's ok to get false alarm rather than not detecting the emergency situation when it really happen. Hence a fast and easy way to verify alert is important here.
One possible way to improve the coverage of detection is by pacing the carpet inside the room and it can detect vibration or sound of a fall. Not sure if there are any technology out there that can do this. But still need a way to verify alert fast and easy.
