Abstract

A multiple touch UI technique for multiple touch enabled devices is disclosed. The UI technique leverages multiple touch capabilities of multiple touch devices. Items of a menu may be selected by pointing on their graphical representations of the item in the menu or according to the number of contact points. Further, keeping the menu button pressed in the menu bar prevents the menu from closing automatically once the item selected. Having the menu bar open allows multiple selections. For example, in case of items associated with a mode to control continuous value such as paging or windowing, the user can directly start manipulating such value by keeping one or more fingers on the screen and dragging. The UI technique enables easy 3D review of medical images on mobile devices and may also be modified to benefit other applications that involve frequent activation of functions selected from a collection of menus.

MULTIPLE TOUCH USER INTERFACE (UI) TECHNIQUE

BACKGROUND

 

The present disclosure relates generally to user interface techniques and more particularly to a multiple touch user interface technique.

Reviewing medical images of anatomy to get a 3D perspective on a 2D screen is complex and involves large number of functions and control modes such as window-level, paging through images, zoom, 3D rotation, 3D rendering, and needs frequent switches between these control modes or multiple tools. With the increased use of cloud and mobility of data, the need for 3D review capabilities on tablet devices has also increased. Tablet devices present additional challenges due to the specificities of such devices, such as size and finger-control.

There are various conventional UI techniques of such devices. One conventional technique is gesture-based menus but the device needs to be put in a command mode before being used so that the gestures do not overlap with the other interactions that are issued on the canvas (for example, paging, panning, zooming, etc). Also, the gesture-based menus do not leverage a user`s prior knowledge and habits associated with traditional menu bars.

Another conventional UI technique referred to as finger-count technique leverages the number of fingers used to select items of a menu. The fingers of the left hand are used to select the menu and the fingers of the right hand to select the item of the menu. However, the finger-count technique requires two hands and thus, is ill-suited for mobile interaction.

Yet another conventional technique enhances menu bars with faster shortcut interaction. The thumb of the hand is used to open a grid-menu spread across the whole screen and one of the other fingers is used to press menu item buttons. However, this conventional technique relies on pointing and is likely to be error prone in expert mode.

It would be desirable to have an improved UI technique for mobile devices.

DETAILED DESCRIPTION

A multiple touch UI technique for multiple touch enabled devices is disclosed. The multiple touch UI is also referred to herein as Multi-touch-Toolbar. The Multi-touch-Toolbar is a UI technique that enhances standard menu bars by leveraging multiple touch capabilities of multiple touch devices. The Multi-touch-Toolbar enables easy 3D review of medical images on mobile devices such as tablet devices.  The Multi-touch-Toolbar may be modified to benefit other applications that involve frequent activati...
