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.
