Nice Pen-based Input Research

One of the things I enjoy to using this blog for is to share cool projects from Human-Computer Interaction (HCI) research. This post highlights projects by Gonzalo Ramos (or "Gonzo" for short) and his co-authors. He has worked on several projects demonstrating how much better pen input software could be. These are just a few I like.

1. The Zlider - A pressure sensitive slider widget that adds additional navigation and control capability to standard slider interactions. Academic research video below. Quick demo montage at beginning, but the demo meat is at 3:07


2. Using a Pen to Effortlessly Bridge Displays. Using a stylus, you can simply drag documents between computer screens or mobile devices. The pen motion also implicity defines the orientation of the displays relative to one another. Academic video below. Demos at the beginning and more mobile screen scenarios at around 2:43


3. Rolling the Pen as Input Using an external tracker and a Wacom tablet, rotating the pen in your fingers can be used to control another parameter without moving the stylus. Academic video below, demo meat at 2:19


You can check more of his projects on his website.

  1. Awesome set of videos, thanks!

    Keeping user interaction focus, and strengthening interaction stimulus are definitely key problems.

    It's a pity that WIMP is such a dominant paradigm - we can clearly do better today!

  2. amasing...

    I think the pen roling its one thing would be possible with IR pen + wiimote, i am right ???

    We can put for example 2 IR in one unic PEN, and wiimote can track both of them..

  8. It is a real prototype that leverages a real communications infrastructure. The devices broadcast their pen gestures to a stitching server that detects when a stitching gesture takes place.

    The applications in the devices then receive the stitching (and geometry) notification and act accordingly, e.g., creating a connection, transmitting a picture, etc.

    Thanks for watching!
