A data-dependent gesture interaction query event construction method

Abstract

The invention relates to a method for constructing a gesture interaction query event based on data dependence, which provides feedback of query results of multiple intermediate operations during a continuous multi-touch gesture interaction process according to the change of the track motion state of each touch point. Through the judgment of the division point of the gesture touch track, dynamically determine the construction timing of each intermediate query, and then construct the query event based on the newly added gesture interaction context and the data dependencies on all query tables, and continue according to the subsequent interaction process New interaction context data adjustment query event; the present invention fully considers the space-time continuity and speed characteristics of touch gesture interaction, can actively adapt to touch gesture changes and provide multiple query feedbacks in a continuous interaction process; and based on data dependencies, all The attributes in the query table are reduced to reduce the scale of the query feedback data, which helps to reduce the query response time and improve the feedback fluency of the gesture interaction query.

Description

technical field [0001] The invention relates to a method for constructing a gesture interaction query event based on data dependence, and belongs to the technical field of human-computer interaction and data query. Background technique [0002] In recent years, with the widespread popularization of computing devices supporting multi-touch interaction, touch interaction technology provides users with a new way of accessing and querying data with its natural and easy-to-operate advantages. However, the operation of touch gestures is often a In the process of continuous change, if you wait for the gesture to be executed before constructing the query and feedback the result, it does not conform to the characteristics of real-time response and feedback of natural human-computer interaction. To this end, it is necessary to actively construct queries during the process of touch gestures. This can not only provide near-real-time query feedback responses and obtain intermediate resul...

Problems solved by technology

[0007] To sum up, when constructing a query, the existing technical methods mainly reduce the query load by reducing the number of query tasks or the number of feedback results, and improve the real-time performance of query feedback by splicing fixed feedback data blocks. However, it is necessary to design specific The scoring function or the pre-block processing of the original data is difficult to implement, and the intermediate feedback is relatively fixed, and it does not focus on the query operation changes reflected in the movement evolution of touch gestures.
