  • Add multitouch gesture support to a TouchPad-equipped laptop Add multitouch gesture support to a TouchPad-equipped laptop, published on IBM developerWorks. Implement swipe and pinch gestures for Linux applications by analyzing tools and code needed to add some of this new gesture support on older Linux-enabled hardware. Building on the output of the synclient program, the Perl code presented here allows you to assign specific application functions to "Three-Finger Swipe," as well as Open- and Close-Pinch gestures.

  • Identify speakers with sndpeek Identify speakers with sndpeek, Use sndpeek and custom algorithms to match voices to a pre-recorded library. Create applications to let you know who is speaking in teleconferences, podcasts, and live media events. Build basic assistance programs to help the hearing-impaired identify speakers in a bandwidth-limited context. Local cached text. Demonstration video at youtube.com

  • Identify and verify users based on how they type Identify and verify users based on how they type, Modify the GNOME Display Manager (GDM) to support user verification through keystroke-dynamics processing. Create and store a one-way encrypted hash of your keystroke patterns when entering your user name. Add code to GDM to read current keystroke patterns and permit a user to log in when the characteristics. Local cached text. Slashdot discussion. Writeup at hackszine

  • ThinkPad aerobics: Rotate and shake your laptop to control applications ThinkPad aerobics: Rotate and shake your laptop to control applications, Use synthetic X Window System events and embedded accelerometers to control applications by the movement of a laptop computer. Translate gestures, such as shaking, into mode-switching commands with detection algorithms to interact with applications in new ways. Develop tools to help build the next generation of interfaces that use accelerometers, such as applications for laptops and iPhones. Local cached text. Demonstration video at youtube.com
