Gestures Plan

My thoughts were triggered after I read the Bill Buxton argument.

We must focus on streamlining the interaction. by number of gestures minimum, using them only when they’re required and naturally usable -> Simpler and better SketchUp design and modeling experience. This implies that we should using Multitouch in only one thing -> Camera motions in Sketchup i.e. Zoom, PAN and Orbit.

There are two modes I am thinking about:

MODE 1 Camera = Initialized using a Button1 from a new SketchUp MT Toolbar

1. Zoom - Drag apart two fingers/MT cursors

   

2. Orbit - Keep two fingers constant and move third vertically to the axis of the two.

          X X O ^
   

3. Pan - Drag in any direction with single finger

        O->
   

MODE 2 Drawing = Initalized using Button2 from SketchUp MT toolbar

• SketchUp’s drawing interface is meant to be exploited using single touch (mouse) so we plan not messing around with that - Therefore we’re drawing with the help of mouse emulation and it’ll do. by just checking if the amount of fingers/touches (TUIO cursors) ==1 and then emulating the MOUSE.

Trying to draw in sketchup using MT might be analogical to killing a mosquito with a stick.

So let’s keep the drawing Single Touch
