Multitouch



MultiTouch Overlays for every application, standard sizes for creating touch screen TVs to custom large overlays. Multitouch overlay technologies transformed the interactive market forever, from large scale custom multi touch overlays to standard sizes to make any TV a Touch TV. Multi-touch, in a computing context, is an interface technology that enables input through pressure and gestures on multiple points on the surface of a device. Multi-Touch technology works with TrackPads (or TouchPads) and touch-screen interfaces, like those found on laptops, smartphones and tablets. It allows users to interact with their devices in a multitude of ways, by expanding the number of interface options.

Multi-touch, in a computing context, is an interface technology that enables input through pressure and gestures on multiple points on the surface of a device. Although most commonly used with touch screen s on handheld devices, such as smartphones and tablets, multi-touch has been adapted for other surfaces as well, including touch pads. From our award winning multi-touch displays to our innovative software suite, MultiTaction is changing the way the world works. We create solutions that allow people to connect in real time, share ideas and solve business problems using live data, across teams, and around the world.

Supported Gestures

On some systems, Unity has support for some system gestures, and you can try those out right away. Here's a list:

  • 3 finger pinch to maximize/restore windows
  • 3 finger press and drag to move window
  • 3 finger touch to show grab handles
  • 3 finger double tap -> switches to previous window Winrar for the mac.

  • 3 finger tap followed by 3-fingers hold -> shows window switcher

    • drag those 3-fingers -> change selected window icon

    • release fingers -> selects window and closes switcher

  • 3 finger tap followed by 3-fingers hold -> shows window switcher

    • release fingers -> switcher will kept being shown for some seconds still

    • drag with one or three fingers -> change selected window

    • Delete button for mac. release finger(s) -> selects window and closes switcher

  • 3 finger tap followed by 3-fingers hold -> shows window switcher

    • release fingers -> switcher will kept being shown for some seconds still

    • tap on some window icon -> selects that icon and closes the switcher

  • 4 finger swipe left/right to reveal launcher (if the dock autohide is enabled)
  • 4 finger tap to open dash

Some applications support 2 finger gestures. However, note that 2 finger gestures require extra setup for touchpads in Ubuntu. Also please note that your system may not be supported out of the box, or at all.

Legacy Applications

Ginn provides users with the ability to add gestures for applications that do not directly support gestures. Ginn supports everything from photo viewers and text editors to window managers! Ginn is not installed by default, and has been moved to universe repositories as of Ubuntu 12.10 (Quantal Quetzal)

About

The Wiki

This resource features information about multitouch support for Ubuntu, including:

Multitouch table
  • drivers for a range of hardware
  • a gesture processing system which does the heavy lifting of gesture analysis
  • APIs for developers who want to build gestures into their apps
  • support for gesture-based window management in Unity

Touch Overview

The Ubuntu gesture recognition framework includes several different components and is associated with various tools and projects: Luminar 4 vs lightroom.

  • kernel drivers (evdev, mtdev)
  • a display server (currently only X is supported; there are future plans for Wayland)
  • Grail - the gesture recognizer
  • GEIS - platform/distro agnostic API for gestures
  • Support in toolkits (Qt, GTK)
  • Support for legacy applications (Ginn)

See the 'In-Depth' section below for more information on the projects various aspects (including current work). Architectural information is available there as well.
