The specific implementation manner can refer to the following embodiments.

[0086] Figure 2 A structure diagram of an intelligent home control system based on a touch display screen is provided by an embodiment of the present application. The embodiment can be applied to the server in the above scene. As shown in the following, Figure 2 The intelligent home control system based on the touch display screen 200 of the embodiment includes a touch display screen 201, a pressure sensing analysis module 202, a region division module 203, a state analysis module 204, and a light analysis module 205.

[0087] The touch display screen 201, the pressure sensing analysis module 202, the region division module 203, the state analysis module 204, and the light analysis module 205 are sequentially connected. The touch display screen 201 is used to contact the user's finger, and obtain pressure sensing capacitance data. The pressure sensing analysis module 202 is used to obtain the pressure sensing capacitance data of the touch display screen, and determine whether there is a pressure sensing change in the touch display screen according to the pressure sensing capacitance data. The region division module 203 is used to analyze the pressure sensing capacitance data when there is a pressure sensing change, and determine the center region and the deviation region of the finger. The state analysis module 204 is used to determine the sliding state according to the center region and the deviation region. The light analysis module 205 is used to predict the light selection possibility according to the sliding state, and determine the final pointing region according to the light selection possibility and perform high display on the final pointing region to prompt the user to select.

[0088] The touch display screen 201 can be a capacitive touch screen that can receive a user touch operation, such as a tablet, a smart central control screen, a magic control switch, and the like.

[0089] The pressure capacitive data can be specific data reflecting the pressure of the user's finger on the touch display screen, the change in capacitance, and the change in the range of capacitance generated.

[0090] The central region can be a region determined according to the pressure capacitive data, and the position of the user's finger is divided. During the sliding process, the region can keep the finger and the touch display screen from being separated.

[0091] The deviated region can be a region determined according to the pressure capacitive data when there is a pressure change, and the finger deviates from the central region. The deviated region surrounds the central region, such as the pressure change caused by the finger pressing down on the left side and lifting up on the right side.

[0092] The sliding state can be the current operation state of the user determined according to the user's sliding state and the selected light color, brightness, and the like, such as sliding start, sliding acceleration, sliding deceleration, sliding end, and the like.

[0093] The light selection possibility can be a possible light selection predicted according to the user's sliding state and the current applicable light and the like. The possible light selection refers to a range of the adjustment bar, such as cool color, warm color, color temperature 5000K-6500K, brightness 10%-20%, and the like.

[0094] The high display can be a display mode determined by the applicable light and the adjustment range and the like information for improving the user's visual perception and experience of the light, such as magnifying the adjustment bar range of the light selection possibility.

[0095] Specifically, when adjusting according to the user's sliding state and the selected light color, brightness, and the like, the brightness and color of the existing light can be infinitely adjusted, but in the existing light adjustment, people cannot accurately select the ideal light brightness and color to complete the atmosphere matching of different lights in the room or the lighting demand, which also causes the infinitely adjustable function to become a mere decoration. This rough light adjustment precision also reduces the user's experience and affects the adjustment difficulty.

[0096] The user contacts the finger through the touch display screen 201, the pressure analysis module 202 obtains the pressure capacitive data, and determines whether there is a pressure change. When there is a pressure change, the region division module 203 determines the central region and the deviated region of the finger according to the pressure capacitive data. The state analysis module 204 determines the sliding state according to the central region and the deviated region. The light analysis module 205 predicts the possible light selection according to the judgment of the state analysis module, and determines the final pointing region according to the predicted light selection, and performs high display on the region to prompt the user to select.

[0097] Through the present solution, through the pressure analysis, area division, state analysis and light analysis modules, the focus area and deviation area of user attention can be accurately determined according to the pressure and capacitance change of the user's finger, and then accurate light adjustment is provided. According to the user's needs and time information, the appropriate light can be intelligently selected to meet the user's actual needs, while reducing unnecessary energy consumption. Through high display, the user's visual perception and experience of light are improved, and the user can more intuitively select and adjust the light, thereby improving the user's experience. According to the user's sliding direction, frequency and acceleration information, the display mode can be automatically adjusted to adapt to the needs and habits of different users. Through the touch display screen and stepless adjustment function, the user can more conveniently control the light without complex operation and professional knowledge.

[0098] In some embodiments, the area division module 203 can obtain a light start-stop record, determine a touch operation record according to the light start-stop record, analyze the touch operation record to determine historical capacitance data, analyze the historical capacitance data, determine a touch capacitance change range according to the analysis result, determine a center area of the user according to the touch capacitance change range, analyze the pressure capacitance data based on the center area, determine the center area and a real-time capacitance change range, and determine a deviation area according to the real-time capacitance change range and the center area.

[0099] The light start-stop record can be data recording the start and stop operations of the light.

[0100] The touch operation record can be various touch operation events of the user on the touch display screen, such as clicking, sliding, etc.

[0101] The touch capacitance change range can be the real-time change range of the capacitance change caused by the touch operation action of the user on the touch display screen, which can be used to judge the contact area, action strength and sliding direction of the user and the touch display.

[0102] Specifically, the starting and stopping operations of all lights are collected and recorded, and the records are saved as light starting and stopping records. According to the light starting and stopping records, a user's touch operation record is analyzed; the touch operation record is a short-term record, which is the touch operation history after the display screen is turned on this time, so that the size of the center area analyzed can be different due to different touch habits and finger sizes of different users. Through analysis of the touch operation record, a series of historical capacitance data can be determined. According to the analysis result of the historical capacitance data, the touch capacitance change range is determined. Based on the touch capacitance change range, the center area of the user is further determined. Finally, the deviation area is further determined on the basis of the center area and the current pressure-sensitive capacitance data, and is the real-time capacitance change range of the extension of the center area according to the area change region in the contact process between the finger pulp and the touch display screen determined according to the pressure-sensitive capacitance data.

[0103] Through the scheme, the user's touch position and action can be accurately positioned by collecting and recording the starting and stopping operations of all lights and analyzing the user's touch operation record according to the records, so as to determine the center area. Since the touch operation record is a short-term record, the touch operation history after the display screen is turned on this time, different user usage habits and finger sizes can be adapted, and the size of the center area analyzed is different. Through analysis of the touch operation record, a series of historical capacitance data can be determined. According to the analysis result of the historical capacitance data, the touch capacitance change range can be adjusted in real time, so as to adjust the determination of the center area in real time. Based on the center area and the current pressure-sensitive capacitance data, the deviation area can be further determined. The deviation area is further determined on the basis of the center area and the current pressure-sensitive capacitance data, and is the real-time capacitance change range of the extension of the center area according to the area change region in the contact process between the finger pulp and the touch display screen determined according to the pressure-sensitive capacitance data.

[0104] In some embodiments, the state analysis module 204 can determine the change end of the deviation area and the contact change of each change end according to the real-time capacitance change range; determine the contact incremental change end and the change speed according to the contact change, and take the contact incremental change end as the sliding direction; determine the sliding direction and the change speed as the sliding state.

[0105] The change end of the deviation area can be the change of the area generated by the capacitance in the area covered by the deviation area on the touch display screen when the user performs a sliding operation.

[0106] The contact change can be a change in the contact state between the finger and the touch display screen during the user's sliding process, including an increase or decrease in the contact area.

[0107] The change speed can be the capacitance change speed of the change end of the deviation area during the user's sliding process, which can reflect the speed of the user's sliding.

[0108] The sliding direction can be the direction in which the user slides on the touch display screen, and can be left, right, up or down, etc.

[0109] Specifically, by analyzing the real-time capacitance change data, the change end of the deviated area and the contact change of each change end can be determined; by identifying and analyzing the trend and speed of the contact change, the sliding direction can be determined as the contact incremental change end; in simple terms, when the finger slides on the touch display screen, the area covered by the capacitance of the deviated area will change, for example, when sliding to the left, the left part of the finger under the finger will press down, and the contact area with the touch display will increase, and the right part of the finger will slightly lift up, and the contact area with the touch display will decrease, so the area covered by the capacitance on the left side of the deviated area will increase, and the area covered by the capacitance on the right side of the deviated area will decrease. The sliding direction is matched with the preset sliding state, and the sliding direction is taken as part of the sliding state; the change speed is matched with the preset sliding state, and the change speed is taken as part of the sliding state; the duration and intensity of the sliding state can be determined according to the change speed.

[0110] By this scheme, by analyzing the real-time capacitance change data, the change end of the deviated area and the contact change of each change end can be accurately determined, so as to realize accurate positioning of the user's finger on the touch display screen, and by identifying and analyzing the trend and speed of the contact change, the sliding direction and the change speed can be determined in real time to determine the real-time action of the user's finger on the touch display screen. Thus, different functions can be bound in different sliding directions, including but not limited to: light color temperature adjustment by sliding up and down, UI interface pops up vertical color temperature adjustment bar, light brightness adjustment by sliding left and right, UI interface pops up horizontal brightness adjustment bar.
