Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0019] The invention takes reducing the operator's cognitive load and operational load on gesture commands as the primary goal, reveals the cognitive mechanism and behavior model characteristics of the flexible mapping between gestures and semantics, proposes and implements a flexible mapping algorithm, so that the operator can use the same Gestures express different gesture semantics, and experiments and verifications are carried out on the interactive smart TV platform, so that the operator can perform natural, smooth, non-contact intelligent interaction with the computer through gestures. The key problem in achieving the above goals is to find the cognitive mechanism linking gestures and semantics in the same interaction situation, mine the implicit features of the operator’s behavior model, and finally establish a flexible mapping between the same gesture and multi...

Abstract

A gesture control method based on flexible mapping between a gesture and multiple meanings of the invention comprises the following steps: first, screening out possible interaction intentions of an operator; then, further narrowing down the gesture meaning of the operator to a smaller meaning set based on interaction context information; and further locking the gesture meaning of the operator based on SDFBM characteristics. The beneficial effect is that one gesture can correspond to multiple meanings, the number of gesture commands needing definition is reduced, so that users can complete gesture command interaction without memorizing gesture commands or by memorizing gesture commands as few as possible and can complete an interaction task naturally without memorizing a large number of gesture commands, interaction is not interrupted or the smoothness of interaction is not affected due to wrong operation of an operator, and the cognitive load and operation load on users are greatly reduced.

Description

technical field [0001] The invention relates to a gesture control method based on flexible mapping between gestures and multiple semantics. Background technique [0002] At present, in the process of assembling a virtual machine with gestures on an interactive TV, it is often necessary to perform many operations such as zooming, rotating, grabbing, releasing, moving, confirming, and canceling scene objects. Generally, one gesture corresponds to one function Commands, so often need to define a lot of gesture commands, and lack of efficient error correction methods, which bring a huge cognitive load and operational load to the user. Let the user not memorize or memorize the gesture commands as little as possible to complete the gesture command interaction, especially under the single-channel input condition of gesture, let the operator use the existing experience or knowledge to complete the interaction task naturally without having to memorize a large number of gestures The ...
