Problems solved by technology

[0003] Because of the small size of the keys set in mobile devices and remote control devices, it is difficult to find the correct key just by looking at the keypad
Even if the correct key is found, it is difficult to tell which key was touched because the finger covers the touched key
Therefore, the problem to be solved in the prior art mobile devices and remote control devices is that the touched key cannot be visually confirmed until the key is pressed
This type of mobile or remote control device may be difficult for the elderly or those with poor vision to use because the indicators on the keys are small and difficult to discern

[0027] Referring to Fig. 1, there is shown a data input device according to a first embodiment of the present invention. The data input device has a display 100, a screen 101, a processor 102 and an input keypad 104 with a plurality of keys. Here, the keypad includes the keyboard. Each key is indicated with a specific visual indicator. The data entry device may be provided in a cell phone, a television remote control or any other mobile device and remote control device as defined above. Keys and displays define the system to which data is entered.

[0028] In the case of a cellular phone, the keypad 104 has numeric keys 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0, as well as some function keys such as "* and #". According to the first embodiment of the present invention, each key is formed by two-stage sensing means, including touch sensing and pressing sensing. The surface of each key is coated with a thin film that can sense the touch of a human finger. Additionally, each key is as...

[0042] Referring to Figures 5 and 6, a flowchart is shown to illustrate the pop-up display 110 according to the second embodiment. The difference between the flow chart of FIG. 5 and the flow chart of FIG. 4 is that a subroutine step S3 is also added. The flowchart of Fig. 6 shows the details of the subroutine step S3. Before explaining the details of the flowcharts of Figures 5 and 6, the functions of the keys in the different modes are described.

[0043] In the case of a cellular phone, in digital mode, the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 are assigned to keys 1, 2, 3, 4, 5, 6, 7 respectively , 8, 9 and 0.

[0044] When changing the key mode to some other mode, keys 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 are assigned characters or functions. For example, as shown in Table 1 below, when the alphabet mode is selected, the keys are assigned letters.

Abstract

A data input system has a key pad with a plurality of keys and a display. The selected key is displayed in the display, but the character size of the selected key on the display is small and difficult to recognize. The face of the selected key appears on the display as a pop-up display in an enlarged scale. Thus, it is easy to recognize the selected key.

Description

technical field [0001] The invention relates to a data input method and equipment. The data entry system has: a keypad with a plurality of keys; and a display for displaying input data. The present invention provides the pop-up display of the key when the key is touched. Background technique [0002] Currently, mobile devices and remote control devices are very advanced and highly developed. For example, mobile devices are cellular phones, PDAs (Personal Digital Assistants), notebook PCs (Personal Computers), and remote devices are remote controls for audio and video appliances. Mobile devices and remote control devices have multiple keys in a small area, so it is difficult for the user to hit the correct key, especially when using the device in a dark place. Furthermore, since fingertips usually cover the key surfaces, it is difficult to confirm which key is touched before pressing it. An example of keys used in a PC is disclosed in Japanese Document 2002-323845. [00...
