This video covers the Sixense Tuscany Demo using the Oculus Rift and Razer Hydra. This was the first time I ever properly used the Razer Hydra, and the experience in conjunction with the Rift was incredible. A new thing I learned during this demo is that using a swivel chair is a bad idea; I find myself turning and not facing the base of the Razer Hydra, which explains the issues I was having in the beginning with my hands not matching up with my body. The 12:07 mark is when things really get going.
And, yes, I'm aware that you can't use both hands to grasp an object, but it felt wrong not to do it with the larger ones.
