Wearable device to interact with IoT

Hey guys, new to IH here. I'm working on a device that will allow the user to interact with devices in their IoT as well as other bluetooth-enabled devices by just moving their hand (remotely and without having to hold any kind of controller). I'm looking for people who find this interesting and would be willing to give me a few minutes of their time to talk about what they'd use this kind of tech for/what they'd like it to be able to do. Just reply to this if interested!
