I'm in the industry and I have to agree here. All of the devices we develop and use (third-party) either already have this capability built-in to the device or are working on it right now.
I agree it is an active area and other people are working on the problem, but can you be more specific about the capabilities that you have seen in other products?
Essentially all of the events you mention plus a good amount more are either in an active product development pipeline for vendors we work with or are actively being worked on internally on devices we are building.
It's a tough space.. margins on these hardware devices are thin already, and sometimes negative as they are simply loss leaders hooking in users for long-term saas payments, so in our case, it's cheaper to build it in-house.
I completely agree with you re margin on the hardware being low. We are not planning on making any money on the hardware. But I also believe it is not possible for startups/companies that don't have copious resources (like Google and Amazon) to do great at both hardware and AI (i.e. build cutting edge AI/CV tech)... Thank you :) If you'd be up for discussing this further, may I ask you to email me? (rafiee at visualone.tech)
