Surface Globe
Yet there is one glimpse of a more serious application. Microsoft's Surface Globe, originally developed for the larger Surface tabletop', gives you some indication of what multi-touch can do within an information app.
It's effectively a multi-touch take on Google Earth using data pulled from Microsoft's Virtual Earth servers, and it's a joy to navigate with hands rather than a mouse. Dragging, rotating, pinch-zooming and flicking all work like a charm.
Suddenly, multi-touch makes sense.
3D benefits
In fact, it's clear that multi-touch is a much more natural way to handle 3D or heavily visual content than the old keyboard and mouse.
A Swedish company going by the name of Natural-UI has its own multi-touch UI framework, Snowflake, which you can run on top of Windows 7, and one of the applets used to demonstrate it is a basic 3D viewer.
It's a great demonstration of how well suited multi-touch is to viewing 3D content. Say you want to pan around an architectural model or zoom in for more detail. There's no more messing around with sliders or clicking and dragging around the model. Just touch, drag, and move the model into the right position.
Does touch have the precision for creating 3D objects in CAD or 3D modelling packages? Probably not. But does it make sense when it comes to taking a look around them or sharing them with others? Definitely so.
