Embodiment Construction

[0035] figure 1 An example gesture recognition device 100 is shown. figure 1 The top portion of is showing the front surface of the device 100. Device 100 may be, for example, a smartphone, or any other device capable of detecting and recognizing gestures made by a user. In the example shown, the apparatus 100 includes a screen 101, which may be a touch screen, eg, that of a conventional smartphone.

[0036] figure 1 The bottom portion of FIG. 1 shows a view of the interior of the device 100. Apparatus 100 includes an array of antennas 102, which may be arranged as illustrated in a rectangular array. The array 102 may be, for example, an array of near field communication (NFC) antennas, capable of transmitting and receiving electromagnetic waves, and especially radio waves in a near field system. The array of antennas 102 may be operable to perform a number of functions. For example, they can act as antennas for normal NFC readers, enabling communication with NFC tags. ...

Abstract

The invention discloses a gesture recognition device (100) for recognizing a gesture made by a user. The apparatus includes: a gesture detector for detecting a gesture made by a user; and a gesture analysis block comprising: a memory configured to store known gestures; and a pattern recognition block for the pattern The recognition block is configured to correlate the gesture detected by the gesture detector with known gestures stored in the memory. The apparatus (100) additionally includes a magnetic field generator for interacting with the wearable tag (200), the magnetic field generator being configured to provide a magnetic force (202) on the wearable tag (200) when the gesture analysis block recognizes a particular gesture.

Description

technical field [0001] The present invention relates to gesture recognition, and in particular to gesture recognition for providing sensory feedback in response to gestures. Background technique [0002] Many electronic devices require the user to perform certain gestures to interact with the device, for example, swiping across the screen of a smartphone to unlock the device. These devices typically require the user to physically touch the device in order for the gesture to be recognized. This is not always desired. For example, with virtual reality devices, having to physically touch the touchscreen to interact with the device may limit the virtual reality experience and / or be impractical (eg, if the touchscreen is positioned close to the user's eyes). [0003] Furthermore, devices typically do not provide any kind of sensory feedback to indicate that a gesture has been performed. This can also limit the virtual reality experience and interactivity with more conventional...
