A Dragon Torched My Hand (How Do VR Haptic Gloves Work?)

submitted by eric3579

There are tons of things I had never considered about how difficult it is to fool your brain into thinking it's touching something it's not. I think the most important technical issue to overcome is timing. Much like how your brain can understand hearing someone's voice AFTER seeing their lips move, but not the opposite... the lag time of the sense of touch is an important thing for your brain. Another thing I hand't considered is the "rise time" that has to do with internal stresses in your fingers. If you conceptualize your fingers as water balloons around bones, you can understand how the internal pressure of your fingers rise the harder you press something. This type of information coupled with the "Sensory Homunculus" make for some incredibly fulfilling thought experiments.

The temperature question is something I'm particularly interested in. Using a colder fluid to model a room temperature fluid because of the heat transfer equation is a fascinating area of scientific problem solving. If you think it through, everything about this boils down to differential equations. How much heat is leaking out of the hand, and at what rate, through what contact area?

I asked HaptX for a blurb to explain their company. This is what they came up with:

HaptX is a multidisciplinary team of engineers based in San Luis Obispo, CA and Seattle, WA that builds advanced haptic technology. Their first product, HaptX Gloves, brings touch feedback to VR with unprecedented realism, enabling a new category of industrial training simulations. Founded by Jake Rubin and Dr. Bob Crockett in 2012, HaptX won’t stop until you can’t tell what’s real from what’s virtual. Learn more at haptx.com.

If you're interested in working for them, here's a link:

In his first video he used the haptic glove in a virtual space

Super interesting. I feel like we're getting a view of Jobs and Wozinak's garage in the late 70s. All these words and concepts they've had to make up. It's going to be amazing in about 3 years.

By far the best class I took while getting my Computer Science degree was "Software Engineering Project". We got assigned a project and divided up into teams including CS, CIS, and MIS majors. The MIS people managed and divided up assignments, and the CS people handled different aspects of the programming, like data structures / algorithms / UI / whatever.

This looks like an extremely fun and interesting extension of that. There's CS guys programming, EE guys doing hardware / sensors / haptic panels, full-on Engineering guys doing fluid dynamics, etc.

Destin seems like a great "jack of all trades" type that can get in there and ask really smart questions off the cuff. All the guys geeking out and being impressed with his intuitions and yet hesitant to confirm anything is hilarious to watch.
