Embodiment Construction

[0011] The detailed description described below in conjunction with the accompanying drawings is only intended to describe various configurations, and does not intend to indicate that the concepts described in the present application can be realized only by these configurations. The detailed description includes specific details in order to provide a thorough understanding of various concepts. It will be apparent, however, to one of ordinary skill in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring these concepts.

[0012] Aspects of the gesture recognition system will now be presented for various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (col...

Abstract

An apparatus, a method, and a computer program product for detecting a gesture of a body part relative to a surface are provided. The apparatus determines if the body part is in proximity of the surface. If the body part is in proximity of the surface, the apparatus determines if electrical activity sensed from the body part is indicative of contact between the body part and the surface. If the body part is in contact with the surface, the apparatus determines if motion activity sensed from the body part is indicative of the gesture.

Description

technical field [0001] In general, certain aspects of the present disclosure relate to gesture recognition, and more specifically, to the use of electromyography (EMG) for the recognition of subtle gestures on surfaces. Background technique [0002] Systems and applications for implementing Augmented Reality (AR) have become very popular and pervasive. AR systems typically include a head-mounted display (HMD) that allows users to simultaneously see and interact with things around them while interacting with applications such as mail and media players. While many AR applications run on smartphones and tablets, the most natural form factor for implementing an AR system is an optical device, such as glasses. [0003] Traditional methods for interacting with applications through AR glasses include gestures, in which different large movements of the wearer's hand within the field of view of the AR glasses initiate different operations on the glasses. However, these methods suff...
