Problems solved by technology

[0005] The range of pressure information utilization is relatively limited, and it only works in specific situations, and all of them use pressure as an explicit control factor;
[0006] (2) These schemes do not apply pressure to the language model for optimization
[0011] (3) In these solutions, users only use one finger in most cases, resulting in very slow typing speed
[0012] (4) Users need handheld devices and cannot type in a relaxed situation

Embodiment Construction

[0065] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] Before that, some terms in this article are explained.

[0067] "Pressure image": on the touchpad or touch screen, detected by the pressure-sensitive sensor array, the pressure signal data at every moment during the text input process.

[0068] figure 1 A general flowchart of the text input method 100 according to one embodiment of the present invention is shown.

[0069] In step S110, pressure image information is collected frame by frame from the pressure touch panel.

[0070] In one example, the pressure image information is obtained from the pressure touchpad at around 130 Hz.

[0071] In step S120, a click is identified according to the magnitude of the pressure, the magnitude of the pressure region, and the duration.

[0072] In one example, identifying a click based on the pressure magnitude, pressure region size, and duration ...

Abstract

The invention provides a text input method utilizing a pressure touchpad, intelligent electronic equipment and a computer readable storage medium. The method comprises the steps: collecting pressure image information frame by frame from the pressure touchpad; identifying a click according to the pressure, the pressure area size and the duration; judging whether the key is a multi-time continuous key or not; and calculating the probability of each word under the condition that the keys are continuously pressed for multiple times, and outputting candidate words of which the probability numericalvalues are ranked at the front preset digit. Due to the fact that the characteristics of the reaction pressure information are utilized, the palm and the click pressure can be distinguished, a user can be allowed to put the palm on the touchpad for input, and the method is quite friendly to the user; accurately identifying the text input by the user; the method is especially suitable for user single-hand input; the method is suitable for multi-finger input of users.

Description

technical field [0001] The present invention generally relates to text input on a touch screen, and more particularly relates to a text input method using a pressure touch panel and an intelligent electronic device. Background technique [0002] In recent years, more and more mobile devices have emerged, but text input on touch screens still faces great challenges. First, due to size limitations, it is impossible to directly transplant the two-handed typing technology of the existing physical keyboard; second, the lack of tactile feedback makes it difficult for users to click on a key; third, many devices cannot distinguish between intentional and unintentional clicks, so users cannot use palms or keys when typing. Rest your fingers on them. For example, on a common tablet, the user's typing and clicking with both hands is not only inaccurate, but also accidental touches of the palm or fingers may occur, and such typing experience is likely to cause fatigue. [0003] The p...
