Embodiment Construction

[0024] In order to make the purpose, features and advantages of the present invention more comprehensible, specific embodiments are given below in conjunction with the accompanying drawings for a detailed description.

[0025] Currently, touch-based interactions on mobile devices are very common, and users often use applications such as text messages, emails, and notepads on these devices. In these applications, the cursor is often used to specify the specific location where text entry and editing tasks are performed. Since the text on mobile devices is small and the fingers used for touch interaction are relatively large, the touch area of ​​the finger may cover multiple characters in different rows and columns, which makes it inefficient to position the cursor on the target location And prone to error. In addition, characters on a touch screen tend to be small and adjacent to each other, making it particularly difficult to position the cursor between two adjacent narrow cha...

Abstract

The invention belongs to the field of human-machine interaction and particularly relates to a multi-channel accurate target positioning method for touch equipment. According to the multi-channel accurate target positioning method, touch input and voice input are used for positioning the target, wherein the touch input is used for providing a possible target object candidate set; the voice input is also used for providing a possible target object candidate set; and the possible target object candidate sets are positioned to an accurate target object by a multi-channel fusion algorithm. According to the multi-channel accurate target positioning method disclosed by the invention, two natural input channels, such as the touch input and the voice input as well as two natural interaction manners are supported; more accurate target positioning can be carried out; and the efficiency of positioning relevant tasks on the touch equipment is increased.

Description

Technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a multi-channel precise target positioning method for touch-control devices. Background technique [0002] On touch devices, some tasks often require the user to locate the target object before performing subsequent operations. For example, in text editing operations, it is often necessary to position the cursor to the target position first, and then perform operations such as insertion and deletion; For the operation of a single object, the target object needs to be selected first. However, due to the large contact area between the finger and the touch screen (reference: Fat finger worries: How older and younger users physically interact with PDAs. In Proc. INTERACT 2005, 267-280.), it is often impossible to accurately select or position to the target audience. Therefore, it is particularly important to provide users with effective and accurate target pos...
