    Default Microsoft OmniTouch: Turn your entire world into a touchscreen

    Now, here’s what we want to see more from Microsoft - innovation.
    Two teams at Microsoft Research have been working on two very
    exciting projects and presented their findings at UI symposium UIST
    2012. The first project, OmniTouch, is the most eye-catching with its
    futuristic idea - turn every surface into a touch-enabled space.

    How did they do it? How about plant a smaller Kinect-like device on
    your shoulder which allows you to interact with all surfaces using
    multitouch, tapping, dragging and even pinch to zoom. Sounds almost
    incredible, and the researchers admit that the first three weeks of
    developing the project were the hardest.

    We wanted to capitalize on the tremendous surface area the
    real world provides,” explains Hrvoje Benko, of the Natural
    Interaction Research group.
    “The surface area of one hand
    alone exceeds that of typical smart phones. Tables are an order
    of magnitude larger than a tablet computer. If we could appropriate
    these ad hoc surfaces in an on-demand way, we could deliver all of
    the benefits of mobility while expanding the user’s interactive capability."

    In order to do that they constructed that Kinect-like device consisting
    of a laser pico projector which would project images on all surfaces
    and a depth sensing camera, responsible for the magic. Tweaking
    the depth camera to recognize human fingers as the source of input,
    as well as adjusting the accuracy of depth recognition was key to the
    success of the project.

    "Sensing touch on an arbitrary deformable surface is a difficult
    problem that no one has tackled before. Touch surfaces are usually
    highly engineered devices, and they wanted to turn walls, notepads,
    and hands into interactive surfaces—while enabling the user to move

    So while by now we’re used to the Kinect user recognition, this was a
    tougher problem to face as it required not only sensing where and how

    the user moves, but whether the user taps on a surface. Since
    those surfaces differ, the depth camera performance was essential.
    The researchers managed to get accurate feedback and detect
    when the finger is 0.4” (1cm) away from a surface. At that distance a
    tap is assumed, and they even managed to maintain that state for
    actions like dragging and pinning. But with no further ado, here’s the
    video about it, visualizing everything we’ve said so far:

    The prototype you see on the image is not small at all, actually it’s ridiculously big for use in public spaces,
    but the research team agrees that there are no big barriers to miniaturizing it to the size of a matchbox. It
    could also be conveniently placed as a watch or a pendant.
    Now, there was also a second ambitious project, PocketTouch, which
    might not look that exciting but if you think about it’s equally thought
    provoking. PocketTouch, as it’s called, aims to allow you interaction
    with your device through different fabrics. This allows “eyes-free” input,
    so you can use all kinds of gesture without having to look at your
    device at all times.

    The results exceeded expectations, and the only thing we have left
    now is wish these technologies arrive sooner to the mainstream.
