Thank you everyone, these are some most useful advices I ever got from HN. I think the people I talked to so far doesn't have exactly the same problem I have, or they don't know they have the problem yet. And I definitely suck at describing my ideas in words. I have already started building the prototype, in the end even if it's just useful to myself, I would still end up with a useful tool and a lot of knowledge gained developing it.
