  1. Very interesting.
    Since 2007 I would like to see a touchscreen-globe. Check out my blog post:,-2011-Terrestrial-globe-with-touch-screen.html

    As you said, 2D Maps have their advantages, but for some use cases a touchscreen globe would surely be suited.

      Interesting, thanks for the link.

      One thing that came to mind, which is an interesting usability problem (imo): When you zoom in further and further on such a touchscreen globe, what happens? The geometry should gradually approach a plane. What does the globe display, especially the regions which are close to the periphery of your vision. And what happens to the “back side” of the globe? What is displayed there?

        It is an interesting design challenge indeed.

        One possibility would be to use only a part of the globe for zooming in. The rest of the globe still displays the globe as before.

        Another one could be to only use the globe for getting an overview of what’s happening around the globe and then when you want to zoom in, use another screen nearby like a wall-screen or a tablet.

    These are interesting suggestions! I’d like to see a prototype implementing that.
