NAVIGATION CONTROL FOR A TABLETOP COMPUTER SYSTEM

摘要

One aspect of the invention is a system for providing navigation control for a tabletop computer system. The system includes a multi-touch display and processing circuitry coupled to the multi-touch display. The processing circuitry is configured to display a user interface on the multi-touch display and render a navigation pane on the multi-touch display. The navigation pane includes a reduced-scale copy of the user interface. The processing circuitry is also configured to detect a touch-based input at a position on the navigation pane and determine a scaled position on the user interface corresponding to the position on the navigation pane. The processing circuitry is further configured to interpret the touch-based input at the position on the navigation pane as an equivalent touch-based input at the scaled position on the user interface and trigger an event corresponding to the equivalent touch-based input at the scaled position on the user interface.
