Parameter inputting method and device

Abstract

The invention discloses a parameter inputting method, which comprises the steps as follows: a datum axis and an indicator are displayed on a user interaction interface, wherein N numerical value display positions are set on the datum axis at equal intervals; the indicator indicates one numerical value display position; when a touch operation on the datum axis by a user is detected, N continuous numerical values are selected from a parameter sequence according to initial numerical values of the numerical value display positions and displacement of the touch operation in an extension direction of a numerical value axis, and are displayed in the N numerical value display positions in a manner of one-to-one correspondence; and the numerical value in the numerical value display position indicated by the indicator is taken as a parameter input. The method cannot be limited by the screen size; accurate selection and inputting of one parameter are achieved under the premise of ensuring that the optional data volume of the parameter is large enough; and the requirements of the data volume of the parameter, the adjustment accuracy and the easiness of operation are simultaneously met. Meanwhile, the invention further discloses a parameter inputting device for executing the parameter inputting method.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a parameter input method and device. Background technique [0002] With the development of the mobile terminal field and the trend of diversification of interactive touch devices, more and more data input is operated by touch, and a slider is a relatively common input method. The input method using the slider has the advantages of flexible and fast operation on the touch device, conforms to human-computer interaction engineering, and provides an effective value range to prevent misoperation to a certain extent. However, due to the conversion of the control mode from the mouse point to the touch surface, it is difficult to accurately locate when the value needs to be adjusted, and due to the limitations of the device area, it is difficult to provide a large number (such as thousands or more than 10,000 levels) ) data to be adjusted. [0003] The specific reaso...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the size of the screen, if you provide a value with a large amount of data and an adjustment with a division value of 1, even the minimum distance between values ​​of one pixel or screen point may not meet the requirements

For example, a handheld terminal with a screen resolution of 1280x720 can only provide data adjustments up to 360 with a division value of 1

[0005] 2. During the adjustment process, it is difficult to locate accurately, which affects the experience: Since the touch area of ​​the finger is a surface, it is difficult to locate when adjusting the slider with dense numerical spacing, which requires very careful operation and is prone to errors

[0006] 3. The space requirements are high, and the layout is limited: in the case of limited space, providing high-precision data adjustment will affect the operation positioning. On the contrary, when providing a more suitable operation distance, the amount of data that can be adjusted cannot meet the demand. It is difficult to strike a balance between the two
