Example Embodiment

[0018] reference figure 1 As shown, the present invention provides a remote control 100 with a one-handed operation text input function, the remote control is used to control a display device, the remote control 100 includes a soft keyboard generator 102, the soft keyboard generator 102 is located in the remote control 100, or by executing software on the remote control 100, so in figure 1 It is represented by a dashed box. In another embodiment, the soft keyboard generator 102 can be directly implemented on the device controlled by the remote control, and the remote control 100 is only used to send commands such as cursor position movement and selection confirmation, and the soft keyboard generator 102 is required to generate a soft keyboard And the cursor position corresponds to the corresponding unit or unit group. The soft keyboard generator 102 generates a soft keyboard 200 composed of a cell array 201 and displayed by a display device (refer to figure 2 ), the soft keyboard generator 102 also displays a selection cursor 202 on the soft keyboard 200 displayed by the display device. The selection cursor 202 covers several units 201 in the unit array. The remote control 100 includes:
[0019] A set of navigation keys 104 for controlling the movement of the selection cursor 202;
[0020] A set of determination keys 106, the number of determination keys 106 corresponds to the number of cells 201 covered by the selection cursor 202, and each determination key in the set of determination keys 106 corresponds to one of the cells 201 covered by the selection cursor 202.
[0021] Combined reference figure 1 with figure 2 In the illustrated embodiment, the soft keyboard 200 generated by the soft keyboard generator 102 includes a rectangular cell array (refer to figure 2 (Shown), each unit 201 displays one of letters, words, symbols or numbers. The size of the soft keyboard 200 can be determined according to the size of the display. Generally speaking, a 6×10 soft keyboard can meet the needs. In addition, the keyboard layout of the 6×10 soft keyboard is similar to the commonly used standard keyboard, so it is easier to accept.
[0022] Continue to refer figure 2 , A selection cursor 202 is also displayed on the soft keyboard 200, and the selection cursor 202 simultaneously covers 4 adjacent cells. Correspondingly, the number of determination keys 106 is also four, and each determination key 106 corresponds to one of the cells 201 covered by the selection cursor 202. The corresponding relationship between the OK key 106 and the unit 201 is determined by their relative positions, that is, the OK key 106 at the upper left corner corresponds to the unit at the upper left of the selection cursor 202, and the OK key 106 at the lower right corner corresponds to the lower right of the selection cursor 202. Unit. The OK button 106 can be realized by an independent button, or as figure 1 As shown, the touch screen is used for implementation. When the touch screen is used for implementation, the touch screen is also divided into four quadrants according to positions, forming four virtual confirm keys 106, and each quadrant corresponds to a unit 201 covered by the selection cursor 202. Regardless of whether it is realized by independent keys or a touch screen, the shape of the keys or the touch screen does not need to be limited. therefore figure 1 The shape shown is just an illustration.
[0023] The remote control 100 also includes a set of navigation keys 104, and the function of the navigation keys 104 is to control the selection cursor 202 to move on the soft keyboard 200. Initially, the selection cursor 202 will usually appear in the middle position of the soft keyboard ( figure 2 The selection cursor shown in the solid line 202). By pressing the navigation key 104, the selection cursor 202 can be moved on the soft keyboard ( figure 2 The selection cursor shown by the dotted line 202). Generally speaking, it is sufficient to provide navigation keys 104 in 4 directions. These 4 directions can be standard horizontal and vertical directions, or figure 1 The arrangement is inclined at 45 degrees as shown. These navigation keys 104 can be pressed individually, or two adjacent navigation keys can be pressed at the same time to point to the direction between the two navigation keys 104. In another embodiment, the navigation key can be realized by a scroll wheel, a joystick, etc., so as to realize movement in any direction. For those skilled in the art, the navigation mode realized by the scroll wheel and the joystick is very common, so it will not be specifically described. The navigation key 104 can also be implemented by a touch screen. If both the navigation key 104 and the OK key 106 are implemented by a touch screen, they can be integrated together. When the touch screen is used, navigation in any direction can be realized, and the principle is similar to the touchpad on a laptop. In addition, different moving speeds or distances of the finger on the touch screen (or scroll wheel, joystick) can also correspond to different cursor moving positions. For example, a slow or small movement to the right can move the cursor one space to the right; a fast or large movement to the right can move the cursor two spaces to the right or to the rightmost space. In this way, the number of operations of the navigation keys can be reduced and faster input can be realized.
[0024] The remote control 100 also includes a function switching key 108, which defines an additional function when used together with the navigation key 104 or the OK key 106. On a standard keyboard, there is For such combination keys, for the remote control 100 of the present invention, these combination keys are set in the function switching key 108, and additional functions are realized by simultaneously pressing the function switching key 108, the navigation key, and the OK key. This additional function can correspond to the standard keyboard The function of the key.
[0025] The function switching key 108 can also be pressed alone. When pressed alone, the function switching key 108 is used to switch between the array soft keyboards. For example, as mentioned above, the soft keyboards generated by the soft keyboard generator are divided into arrays. For example, several 6×10 soft keyboards can be generated to provide richer input functions. These 6×10 soft keyboards can be displayed separately On different display screens, it can also be displayed on the same screen after being appropriately reduced. Pressing the function switch key 108 alone can switch between the array soft keyboards.
[0026] One feature of the remote controller 100 of the present invention is that it can be operated with one hand. Therefore, the arrangement of the keys on the remote controller 100 needs to fully consider the need for one-hand operation. For example, the whole of the remote control 100 can be configured as a handle, the navigation key 104 and the OK key 106 can be set within the controllable range of the thumb, and the function switching key 108 can be set on the side of the remote control 100 to facilitate the use of other Finger operation. Alternatively, the function switching key 108 can also be arranged on the back or under the remote control, as long as it is convenient for one-handed operation.
