GESTURE ENABLED SIMULTANEOUS SELECTION OF RANGE AND VALUE

摘要

A method, gesture input devices and a computer program product are provided for gesture enabled simultaneous selection of range and value. A user makes a gesture with two fingers (210, 220) to select a range of values (e.g. one of a range of seconds, minutes or hours) and select a value from this selected range of values (e.g. if the selected range of values is hours, a value between 00-23 hours). The gesture is captured using a camera based input device or a touch input device, which detects two user input contact points (230, 240). The distance (250) between these two user input contact points (230, 240) determines the selected range of values. The selection of the value from this selected range of values is determined by an angle (280) between two imaginary lines (250, 270). The first imaginary line (250) is the line between the first (230) and second (240) user input contact point. The second imaginary line (270) is the line between an imaginary anchor point (260) and the first user input contact point (230). The distance (250) between the two fingers (210, 220) allows the user to select a range, and rotating the second finger (220) in relation to the first finger (210) allows the user to select a value, within the selected range, as user input.

1. A method for receiving as user input a value, the method comprising the steps of:
detecting, via a gesture input device, a user input contact point, in an imaginary plane; determining a distance, in the imaginary plane, between a reference point and the user input contact point; determining an angle, in the imaginary plane, between a first imaginary line from the reference point to the user input contact point and a second imaginary line from the reference point to a predefined imaginary anchor point in the imaginary plane; selecting a range of values, from a set of such ranges of values, based on the determined distance; and selecting as user input a value, within the selected range of values, based on the determined angle,characterized in that said reference point is an additional user input contact point, the additional user input contact point and the user input contact point respectively defining a first and a second user input contact point.
