Today marks the official close of Valve's Steam Dev Days event in Seattle, where Valve evidently demonstrated at least one prototype of a new controller for the HTC Vive capable of sensing finger movement.
What makes this especially interesting for any devs who aren't at Dev Days this year is that a number of attendees recorded themselves playing with the prototype and put those videos on the internet.
We've taken the liberty of collecting some of those videos here because they shed light on the future of Valve's VR efforts, and reinforce the value of what Oculus has been championing as "hand presence" -- the power hand-tracking has to deepen someone's immersion in a VR experience.
Oculus, of course, plans to begin selling its own finger-tracking Rift controller, Oculus Touch, for $200 later this year.
This isn't the only intriguing bit of controller news to come out of this year's Dev Days, either; yesterday Valve's Jeff Bellinghausen and Level Up Labs cofounder (as well as occasional Gamasutra blogger) gave a talk about how Valve is getting behind the Steam Controller (which is nearing 1M sold) and expanding its Controller API to include other gamepads, starting with the DualShock 4.
