Embodiment Construction

[0034] Circular gestures (rotate finger movement, hereinafter also referred to as "AirWheel") can be used in gesture detection systems to control many different parameters, eg volume or light dimming control, etc. However, movement in non-touch systems is often inconsistent and can be difficult to detect, which can often lead to a poor user experience. Various embodiments of the detection methods disclosed in this application are designed to overcome this possible shortcoming.

[0035] The disclosed methods are not limited to any type of user input device. Therefore, it can be applied to any 2D or 3D inspection system. exist Figure 15 A non-touch gesture detection system is shown in . This 3D gesture detection system uses a quasi-static AC electric field with a 4-frame receiving electrode layout. A transmission electrode (not shown) can be arranged, for example, below these four electrodes 1510, 1520, 1530 and 1540 and cover the entire area of ​​the reception electrodes 1...

Abstract

The invention discloses a method for detecting a continuous circular gesture performed by an object, which may have the steps of: detecting the movement by scanning the movement of the object performing the circular movement and determining subsequent position points of the object, Wherein the reference position of the virtual circular movement is adapted depending on the history of the scanned position points.

Description

[0001] Related patent applications [0002] This application claims priority to commonly-owned US Provisional Patent Application No. 62 / 072,184, filed October 29, 2014, which is hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a method and device for a human-machine interface, in particular, to a continuous circular gesture detection method for a sensor system. Background technique [0004] Known systems for multi-level control (e.g. volume control or screen / light brightness control in consumer electronics) use circular touchpads or capacitive linear sliders (often mounted above the keyboard in laptops), Or the system uses touch information from a generic laptop touchpad as the finger moves in the dedicated slider area (eg, on the right border of the touchpad). These sensors provide absolute position information about the fingertip (possibly ambiguous as in the case of many circular touchpads) and thus the angle o...
