Description

A new touch human-computer interaction processing method

Technical Field

The present invention relates to the field of electronic technology for household appliances, and in particular to a novel touch human-computer interaction processing method.

Background technique

At present, household appliances generally adopt touch button human-computer interaction, with various touch modes and more and more touch buttons. Traditional mechanical buttons have been gradually eliminated by the market due to high failure rate after long-term use and laborious and inconvenient operation. Domestic touch chips have stable performance and low price cost, but the number of touch channels will not exceed 16. Domestic chips with more than 20 touch channels have unstable performance, while foreign imported brands are expensive and are not suitable for small household appliances that are sensitive to price costs; traditional sliding touch is generally an intermittent sliding gesture that cannot be cycled, and it cannot be arbitrarily recognized by sliding over a short distance. The user experience is not good and the product has no market competitiveness.

Summary of the invention

The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a human-computer interaction processing method based on a domestic touch chip to solve the technical problems of the domestic touch chip having few touch channels and unstable performance.

A novel touch human-computer interaction processing method, the method comprising:

Point touch: The first touch chip first identifies the point touch key value, which includes different key values corresponding to touching one or multiple keys at the same time. Then the main MCU performs key recognition timing, and finally makes a corresponding event judgment based on the key value and key duration.

Sliding control ring touch: The second touch chip first identifies the sliding control ring touch button value, which is the button value corresponding to a single button in the annular sliding touch button group. Then the main MCU performs button recognition timing, and finally makes corresponding event judgments based on the changes in the button value within the preset time.

Furthermore, the first touch chip and the second touch chip are both domestically produced low-cost touch chips with less than 16 channels.

Furthermore, the inching touch includes the following four key types, each of which may include one or more key types:

(1) At time T0, a single finger touches one of the keys, and the key recognition cycle timing starts. At time T0+t1, if the key value remains unchanged, it is determined as a single-finger short press triggering event Kv1;

(2) At time T0, a single finger touches one of the keys, and the key recognition cycle timing starts. At time T0+T1, t1＜T1＜t2. If the key value remains unchanged and the key value at time T0+T2 is 0, T1＜T2＜t2, it is determined to be a single-finger short-time release event Kv2;

(3) At time T0, a single finger touches one of the keys, and the key recognition cycle timing starts. At time T0+t3, if the key value remains unchanged, it is determined as a single-finger long press triggering event Kv3;

(4) At time T0, a finger touches two or more keys at the same time, and the key recognition cycle timing starts. At time T0+t3, if the key value remains unchanged, it is determined as a multi-finger long press triggering event Kv4;

Wherein, T1 and T2 are touch times, t1, t2 and t3 are all preset times, and 0＜t1＜t2＜t3; wherein, the same key cannot contain Kv1 and Kv3 at the same time.

Furthermore, the touch function is provided with a plurality of touch buttons, which are divided into the following four types:

(1) The first type of key contains two key types: Kv3 - single-finger long press for 2 seconds to trigger, Kv2 - single-finger short press within 1 second to release;

(2) The second type of key includes one key type: Kv1--single finger short press 20ms trigger;

(3) The third key type includes one key type: Kv2-single-finger short press within 1 second;

(4) The fourth key type includes one key type: Kv4 - triggered by pressing two fingers for 2 seconds;

The following is the recognition process of key types Kv1-Kv4:

①Key type Kv1 includes the following steps:

Step 110, at time T0, a single finger touches any key of the second type of keys to start the key recognition cycle timing;

Step 120, at time T0+20ms, if the key value remains unchanged, the main MCU determines it as key type Kv1;

Step 130, the main MCU subsequently waits for the finger to release the button and clears the touch recognition cycle timer. If the finger is not released, the button recognition cycle timer accumulates and remains unchanged until it reaches the maximum value.

②Key type Kv2 includes the following steps:

Step 210, at time T0, a single finger touches any key of the first key or the third key to start the key recognition cycle timing;

Step 220, at time T0+T1, 20ms<T1<1s, if the key value remains unchanged, the state of the main MCU is key type Kv2 determination enabled;

Step 230, at time T0+T2, T1<T2<1s, the key is released with one finger, and the main MCU determines it as key type Kv2. At the same time, the key recognition cycle timing and key Kv2 determination enable are cleared.

③Key type Kv3 includes the following steps:

Step 310, at time T0, a single finger starts to touch any key in the first type of keys, and the key recognition cycle timing starts;

Step 320, at time T0+2s, if the key value remains unchanged, the main MCU determines it as key type Kv3;

Step 330: the main MCU subsequently waits for the finger to release the key and clears the touch recognition cycle timer. If the finger is not released, the key recognition cycle timer accumulates and remains unchanged until it reaches the maximum value.

④Key type Kv4 includes the following steps:

Step 410, at time T0, the finger touches two or more keys of the fourth type of keys at the same time, and the key recognition cycle timing starts;

Step 420, at time T0+2s, if the key value remains unchanged, the main MCU determines that the key type is Kv4;

Step 430, the main MCU subsequently waits for the finger to release the key and clears the touch recognition cycle timer. If the finger is not released, the key recognition cycle timer accumulates and remains unchanged until it reaches the maximum value.

Furthermore, the sliding control ring touch is a circular sliding control ring touch track formed by more than 12 touch buttons evenly distributed in a ring shape.

Furthermore, the sliding ring touch includes a clockwise sliding gesture and a counterclockwise sliding gesture.

Furthermore, the processing steps of the sliding control ring touch clockwise sliding gesture are as follows:

Step 510, the finger starts to touch the initial key on the sliding control ring, the default timing cycle is reset to zero, and the touch recognition cycle timing starts, and the initial key value is Key "x";

Step 520, if the key value changes to Key "x+1" during the touch recognition cycle timing within the preset time, it is determined to be a one-step clockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key "x+1";

Step 530, if the key value changes to Key "x+2" during the touch recognition cycle timing within the preset time, it is determined to be a one-step clockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key "x+2";

The subsequent steps are similar. If the finger slides in a circular clockwise direction continuously, a clockwise sliding gesture will be continuously generated.

Furthermore, the processing steps of the anti-clockwise sliding gesture of the sliding control ring touch are as follows:

Step 610, the finger starts to touch the initial key on the sliding control ring, the default timing cycle is reset to zero, and the touch recognition cycle timing starts;

Step 620, if the key value of the touch recognition cycle timing changes to the key maximum value Key "y" within the preset time, it is determined to be a counterclockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key "y";

Step 630, if the key value changes to Key "y-1" during the touch recognition cycle timing within the preset time, it is determined to be a counterclockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key "y-1";

The subsequent steps are similar. If the finger slides in a counterclockwise circular motion continuously, counterclockwise sliding gestures will be continuously generated.

Beneficial effects of the present invention:

The touch human-computer interaction processing method is divided into two human-computer interaction modes: point touch and slide control ring touch. Point touch can identify a finger short press or long press of a key or multiple keys. The slide control ring touch is specifically a 360° clockwise or counterclockwise slide control ring touch gesture, which can continuously or at any small angle slide control touch to identify finger touch actions. The operation gesture is novel and creative, and the human-computer interaction interface is fashionable and cool, which can enhance the market competitiveness of the product. The total number of touch channels exceeds 20, the touch performance is stable, the price cost is low, and the anti-interference ability is strong. It solves the problem of few touch channels and unstable performance of domestic touch chips. The present invention can be widely used in household appliances that are sensitive to price costs, such as refrigerators, water dispensers, water purifiers, ovens, etc.

BRIEF DESCRIPTION OF THE DRAWINGS

The above and/or additional aspects and advantages of the present invention will become apparent and easily understood from the description of the embodiments in conjunction with the following drawings, in which:

FIG1 is a schematic structural diagram of an embodiment of the present invention.

Detailed ways

This embodiment is a built-in steam oven, which includes 8 inching buttons and 12 annular sliding touch buttons, which are described in detail in two parts below.

Part 1: Processing of 8 inching buttons

This embodiment has a total of 8 touch keys (key1-key8), which are more specifically divided into the following 4 types:

1. key1 contains 2 key types: Kv3--single-finger long press for 2s to trigger, Kv2--single-finger short press for 1s to release;

2. The five keys key2--key6 each contain one key type: Kv1--single finger short press 20ms trigger;

3. key7 contains 1 key type: Kv2--single finger short press and release within 1s;

4. The two buttons key7 and key8 contain one button type: Kv4--trigger by pressing and holding two fingers for 2 seconds;

The first touch chip can accurately identify the finger touch button action in time, and it transmits the key value information to the main MCU. The main MCU is responsible for processing the key value and converting it into the above 4 valid key types. The first touch chip and the main MCU are both microcontrollers that can read, write and run the program code entered by the technician multiple times. The program code written into the chip storage space is non-volatile.

The following is the specific process of Kv1-Kv4 recognition and processing:

1. Key type Kv1: Triggered by a single finger short press for 20ms. Taking key2 as an example, it includes the following steps:

Step 110, at time T0, a single finger starts to touch key2, and the key recognition cycle timing starts;

Step 120, at time T0+20ms, a single finger still touches key2, and the main MCU determines it as key type Kv1;

Step 130, the main MCU subsequently waits for the finger to release the key2 button, clears the touch recognition cycle timer, and prepares for the next touch recognition. If the finger is not released, the key recognition cycle timer accumulates and remains unchanged when it reaches the maximum value.

2. Key type Kv2: single-finger short press and release within 1s. Taking key1 as an example, it includes the following steps:

Step 210, at time T0, a single finger starts to touch key1, and the key recognition cycle timing starts;

Step 220, at time T0+T1 (20ms<T1<1s), a single finger still touches key1, and the state of the main MCU is key type Kv2 determination enabled;

Step 230, at time T0+T2 (T1<T2<1s), the key1 button is released with a single finger, and the main MCU determines it as key type Kv2. At the same time, the key recognition cycle timing and key Kv2 determination enable are cleared to prepare for the next key recognition.

3. Key type Kv3: Triggered by long pressing one finger for 2s. Taking key1 as an example, it includes the following steps:

Step 310, at time T0, a single finger starts to touch key1, and the key recognition cycle timing starts;

Step 320, at time T0+2s, a single finger still touches key1, and the main MCU determines that the key type is Kv3;

Step 330, the main MCU subsequently waits for the finger to release the key1 button, clears the touch recognition cycle timer, and prepares for the next touch recognition. If the finger is not released, the key recognition cycle timer accumulates and remains unchanged when it reaches the maximum value.

4. Key type Kv4: Triggered by pressing and holding two fingers for 2 seconds. Taking key7 and key8 as examples, it includes the following steps:

Step 410, at time T0, two fingers touch key7 and key8 respectively, and the key recognition cycle timing starts;

Step 420, at time T0+2s, two fingers are still touching key7 and key8, and the main MCU determines that the key type is Kv4;

Step 430, the main MCU subsequently waits for the finger to release key7 and key8, clears the touch recognition cycle timer, and prepares for the next touch recognition. If the finger is not released, the key recognition cycle timer accumulates and remains unchanged when it reaches the maximum value.

In addition, in this embodiment, key1 cannot contain two key identification value types at the same time: triggered by a single-finger long press for 2s and a single-finger short press for 20ms; in this embodiment, when a finger touches any key from key1 to key8, and touches all 12 circular sliding touch keys at the same time, it is regarded as an invalid touch key.

Part 2: Processing of 12 circular sliding touch buttons

In this embodiment, there are 12 annular sliding touch buttons. When a finger slides along the annular track to touch the button, the second touch chip can timely and accurately identify the button value. When the finger slides over the touch key, it corresponds to a different button value. At the same time, the second touch chip transmits the button value information to the main MCU. The main MCU is responsible for processing the button value and turning it into a valid button recognition event. The second touch chip and the first touch chip are both the same type of touch chips.

The 12 sliding touch buttons in this part are evenly arranged in a circle every 30°. 12O’clock is defined as key 1, and clockwise is key 2, key 3, etc. until key 12. The main MCU is set to recognize each key 5ms, and the maximum effective recognition time is 300ms. Sliding the finger along the circular track on the touch button can generate two kinds of sliding gestures: clockwise sliding gesture and counterclockwise sliding gesture.

Specifically, the clockwise sliding gesture recognition process is divided into the following steps:

Step 510, the moment when the finger starts to slide and touch a key is recorded as T0, the default timing cycle is reset to zero (assuming the initial value of the key is Key1), and the key recognition timing starts;

Step 520, when the touch recognition cycle timing accumulates to T1 (5ms≤T1≤300ms), if the key value changes to Key2, it is determined to be a clockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key2;

Step 530, when the touch recognition cycle timing accumulates to T2 (5ms≤T2≤300ms), if the key value changes to Key3, it is determined to be a clockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key3;

Step 540, when the touch recognition cycle timing accumulates to T3 (5ms≤T3≤300ms), if the key value changes to Key4, it is determined to be a clockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key4;

The subsequent steps are processed in the same way. If the finger slides in a circular clockwise direction continuously, a clockwise sliding gesture will be continuously generated. It is worth mentioning that if the T1, T2, and T3 timings are greater than 300ms, a clockwise sliding gesture will not be generated.

As a supplement, in step 520, the touch recognition cycle timing accumulates to T1 (5ms≤T1≤300ms). If the key value becomes Key12, it is determined to be a counterclockwise sliding gesture. At the same time, the timing cycle is reset and the initial key value is changed to Key12. In each subsequent step, the main MCU processes according to the same logic, and can determine whether it is a clockwise or counterclockwise sliding gesture according to the change in the finger sliding direction.

Specifically, the counterclockwise sliding gesture recognition process is divided into the following steps:

Step 610, the moment when the finger starts to slide and touch a key is recorded as T0, the default timing cycle is reset to zero (assuming the initial value of the key is Key1), and the key recognition timing starts;

Step 620, when the touch recognition cycle timing reaches T1 (5ms≤T1≤300ms), if the key value changes to Key12, it is determined to be a counterclockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key12;

Step 630, when the touch recognition cycle timing reaches T2 (5ms≤T2≤300ms), if the key value changes to Key11, it is determined to be a counterclockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key11;

Step 640, when the touch recognition cycle timing reaches T3 (5ms≤T3≤300ms), if the key value changes to Key10, it is determined to be a counterclockwise sliding gesture, and the timing cycle is reset to zero, and the initial key value is changed to Key10;

The subsequent steps are processed in the same way. If the finger slides in a counterclockwise circular motion continuously, a counterclockwise sliding gesture will be continuously generated. It is worth mentioning that if the T1, T2, and T3 timings are greater than 300ms, a counterclockwise sliding gesture will not be generated.

In addition, in step 620, when the touch recognition cycle timing reaches T1 (5ms≤T1≤300ms), if the key value becomes Key2, it is determined to be a clockwise sliding gesture, and the timing cycle is reset, and the initial key value is changed to Key2; in each subsequent step, the main MCU processes according to the same logic, and can determine whether it is a clockwise or counterclockwise sliding gesture according to the change in the finger sliding direction.
