Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings, but embodiments of the present invention are not limited thereto.
It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
Example 1:
a touch remote control system for a tv set, as shown in fig. 1, comprises an image display unit 1, a remote control receiving unit 2, a central processing unit 3 and a remote control transmitting unit 5.
The remote control transmitting unit 5 further includes a touch panel 4 and a key unit 6. The touch panel 4 senses the position of the sensing surface touched by the finger, calculates coordinate data and touch sensing time data of a touch point, and immediately generates new data when the touch panel 4 senses that the finger slides to a new position; the key unit 6 is a remote control function key and can be triggered to generate a corresponding remote control function signal; the remote control transmitting unit 5 transmits data from the touch panel 4 and a control signal of the key unit 6 to the remote control receiving unit 2.
In the embodiment of the present invention, the touch panel 4 may be a capacitive touch panel or a resistive touch panel, and the wireless communication mode between the remote control transmitting unit 5 and the remote control receiving unit 2 may be implemented by infrared, bluetooth or ZigBee technology, which is not limited specifically herein.
As shown in fig. 1, the central processing unit 3 is connected to the remote control receiving unit 2 and the image display unit 1, respectively. The image display unit 1 includes a display focus 7 and a plurality of program icons. After receiving the data and signals of the remote control transmitting unit 5, the remote control receiving unit 2 sends the data and signals to the central processing unit 3. The central processing unit 3 performs calculation processing on the data and the signals, and then moves the position of the display focus 7 on the image display unit 1.
For example, the following steps are carried out: when a large number of movies are selected in the television, the movies are arranged on the image display unit 1 in a matrix, the display focus is moved by the conventional remote controller through up, down, left and right keys, and the display focus 7 is understood as a frame of the selected program, but the remote control system in this embodiment can change the position of the display focus 7 by sliding on the touch panel 4.
Example 2
A touch remote control method for a television, first, a central processing unit (3) reads the position coordinates of a program icon and the position coordinates of a display focus (7) in an image display unit (1). Then the central processing unit 3 receives the touch sensing data transmitted by the remote control receiving unit 2, judges whether the received data has finger touch action, and restarts the processing flow if no finger touch action exists; reading all the induction point coordinates on the touch panel 4 and the display coordinates of all the image display units 1, and establishing a mapping relation; and if the finger touch action exists, calculating the target coordinate of the display focus 7 by using the current touch starting data, the current touch ending data and the position coordinate of the display focus 7. Finally, judging whether a program icon exists near the target coordinate of the display focus 7 or not, and if the program icon does not exist, acquiring new touch induction data again; if there is a program icon, the display focus 7 is moved to the program icon closest to the coordinate position, and then new touch-sensitive data is waited for.
The above-described processing is further described in detail. As shown in fig. 3, the finger is on the touch panel 4 by a0(x0,y0) Slide to An(xn,yn) The touch panel 4 sequentially detects a series of finger touch coordinate data a0(x0,y0)、A1(x1,y1)、…、An-1(xn-1,yn-1)、An(xn,ym) The touch panel 4 sequentially transmits the coordinate data touched by the finger to the remote control receiving unit 2 in real time through the remote control transmitting unit 5. The remote control receiving unit 2 transmits the coordinate data touched by the finger and the touch time data to the central processing unit 3 in real time. When the central processing unit 3 receives An(xn,yn) Then, the reception A is calculated0(x0,y0) To receiving An(xn,yn) Time duration T ofn＝tn-t0Wherein t is0To receive A0(x0,y0) Time of data, tnTo receive An(xn,yn) The time of day of the data. The target coordinate data showing the movement of the focus 7 is:
B(Xb,Yb)＝B0(X0,Y0)+K×(An(xn,yn)-A0(x0,y0))÷Tn(ii) a Namely:
in the above equation, K is a preset constant, that is, a certain proportional coefficient relationship between the moving distance of the display focus 7 and the sliding distance data is preset, in this example, K is 200; b is0(X0,Y0) To show the initial coordinates before the focus 7 is moved, B (X)b,Yb) Is the target coordinate. The above equation controls the preset constant by the average sliding speed.
Coordinate point B (X) on the display image display unit 1b,Yb) When a program icon is present in the vicinity, the central processing unit 3 moves the display focus 7 to a distance B (X)b,Yb) The most recent program icon. As shown in fig. 4.1, when the image display unit 1 is commanded to move the display focus 7 from the start point D1 to the end point B7, the display focus 7 moves along the closest path as the program icons fill the entire image display unit 1. As shown in fig. 4.2, when there is a partial position on the image display unit 1 without a program icon (e.g. missing C3 in the figure), the display focus 7 bypasses the position of the missing icon and followsThe closest path moves. As shown in fig. 4.3, since B6 and B7 are missing in the image display unit 1, the display focus 7 should be moved to B7 but finally to B5. In summary, when the program icons are arranged differently, the moving path of the display focus differs.
The method for determining the moving path of the target coordinate of the display focus 7 is as follows: using the position coordinates and target coordinates B (X) of each program icon respectivelyb,Yb) And (5) calculating the distance and taking the displacement path with the minimum calculated value.
In this example, as shown in FIGS. 4.1-4.3, when the finger is from A (x)0,y0) Slide to B (x)b,yb) The shorter the time (i.e., the fast slide), the greater the distance the display focus 7 moves per unit time; when the finger is moved from B as shown in FIGS. 3 and 50(x0,y0) Slide to B (x)b,yb) When the time of (2) is long (i.e., slow sliding), the display focus 7 moves to the program icons D2, D3, C3, and C4 in sequence during the sliding process, i.e., the distance of movement of the display focus 7 per unit time is small.
After moving the display focus 7 to the target coordinates, the image display unit 1 enters the corresponding program by clicking the touch panel 4.
Example 3
This embodiment is different from embodiment 2 in the formula of the target coordinate moved at the display focus 7, and the rest is the same.
The present embodiment controls the size of the display focus movement distance per unit time by the following equation:
target coordinate is preset constant x sliding distance data ÷ sliding time length + display focus start coordinate
As can be seen from the above equation, the proportional coefficient of the preset constant is controlled by the sliding distance and the average sliding speed data, and the display focus moving distance is proportional to the average sliding speed data of the finger and proportional to the sliding distance of the finger.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
