But why relying on a stand-alone solution and not on phone connectivity? That would seem to me like a more convenient solution to reduce cost and make it less bulky.
There are multiple issues, but the most important one is latency. You basically cannot have any additional in this application. You would have to send it, process it and receive it, introducing significant delays,
There’s slew of gadgets which just came out and latencies introduced by external processing are a major issue.
Wireless connectivity can be really shoddy in congested areas too.
