Calf Trail Software has announced Sesamouse 1.0, a free new utility for extending the gesture capabilities of the Magic Mouse. Sesamouse works by imitating real multitouch trackpad gestures, enabling the user to exercise fine control over pinch and rotate gestures without needing to set up keyboard shortcuts.
Sesamouse also sends the position of each finger as touch information (known to Cocoa developers as a set of NSTouch objects) that can be recognized by more advanced multitouch apps. Users can practice gestures and see how their fingers have been recognized above Sesamouse's own application window.
In a post introducing Sesamouse on their blog, Calf Trail writes, "Since seeing Jef Han's [multitouch demonstration at the 2006 TED conference], it's been obvious that multitouch is a great way to do more stuff with less fuss on the computer." By extending the multitouch capabilities of Apple's Magic Mouse hardware, Calf Trail hopes to open more multitouch benefits to desktop users.
Because Sesamouse does rely on some undocumented system features, Calf Trail is releasing it as a free utility in hopes that it will still benefit both users and developers of multitouch-aware applications. In lieu of donations at this time, Calf Trail is encouraging users to contribute directly to help Haitian small businesses rebuild via a link on the Sesamouse product page.
