Recently I applied some two-hand interaction to the content board in project multi-workstation. Previously, Ken said he wanted to try a horizontal board, not a eyes-free style, but a purely horizontal board. Inspired by that, I think it is worth trying to do content board manipulation. Intuitively, I implemented a simple translation and rotation based on how two hands moved. I have some different idea about scaling, maybe scale the content board, or scale the mapping between user’s movement and the cursor’s movement. In addition, rotate the content board based on how two hands rotated is in progress too. Take a look.
Then I found out a small issue for drawing toggle when two hands are both active. So Karl and I tried a different way of claiming the ownership of drawing. Let’s see how the cursor jumps when the ownership changes.
