elder patients wearing gps wearables will allow geo fencing, watches or clothes that monitor heart beat, temperature , rules engine and Ai analytics that will process the data and generate alerts for each patient, etc. IoT brings a wealth of capabilities that will imptove the care of these patients

Juan brings up going points as well - there's been a lot of research done on the wearables side. For example, besides the larger improvement of care, it's a matter of improving the access of care. For patients who do not have access to vehicles or transportation for PCP visits, wearables can be used as a placeholder to check vitals information (i.e., as Juan mentioned, heart beat, etc.)
In addition, there are other options, such as 'smart' pill devices which can monitor and improve medication adherence and can notify caretakers.

I have come across this product. They claim to provide comprehensive home care for the elderly.

Arnab, I conducted a very comprehensive study on this topic earlier this year and the concept that I developed was based on solutions that are already available and use some combination of IoT, machine vision, geolocation, communication, and monitoring by professionals.
I am impressed that Best Buy is headed in the direction that my client wants to go. They have pulled together a very comprehensive solution "Assured Living" using off-the-shelf products from multiple vendors and connected them so that they talk to each other and to Best Buy staff.
