May I ask what exactly are you looking for in the replacement?

We are actually building a wearable that gives you full hand tracking without the need for line of sight. It's intended for AR/VR applications since it's just as precise as vision based products without all the downsides. But one thing that's personally important to me that we are incorporating into the product is the ability to turn any surface I touch into a trackpad. It basically gives me a portable trackpad anywhere I go and I can sit 10 feet away from my computer and use my leg or arms of the chair to control my computer. I'm curious what kind of usages you need from a product like this.

Well, I don't want to turn arbitrary surfaces into trackpads. I'd just like to be able to perform hand gestures in the air, above my keyboard. I don't need to perform them from across the room or anything like that. So that, to me, is the MVP- simply replacing my trackpad for gestures like pointing, clicking, dragging, zooming in MacOS.

But beyond that...

1. I don't want to wear anything on my hands.

2. I'd like to be able to program new gestures easily. Sort of like American sign language, I want to easily map a gesture to an action.

3. After replacing a trackpad, I'd want to be able to use my hands to manipulate a 3d environment. This requirement is pretty low on my list, because I never do anything in 3D. But it's necessary in the long run, once 3D applications become popular.
