Input device and portable terminal having same

Abstract

To provide the input device in the present invention, which allows comfortable operation with lightened mental and physical load, has at least one input key and includes: an association storage unit storing an array of plural information in association with the input key, the plural information each having an order; a selection unit selecting, from the array, predetermined information as input information; a touch detection unit detecting that an object touches a surface of the input key; and a movement relevant information detection unit detecting movement relevant information concerning a movement of a contact point between the surface of the input key and the object, the contact point being detected by the touch detection unit.; The selection unit selects, from the array, information having a predetermined order stored in association with the input key on which the touch detection unit detects the touch by the object, based on the movement relevant information.

Description

technical field [0001] The present invention relates to an input device having at least one input key, and particularly relates to a technique for performing simple operations on the input device included in a mobile terminal. Background technique [0002] figure 1 It is an external view of a conventional mobile terminal. Such as figure 1 As shown, the conventional mobile terminal 100 is integrated with the operation unit 101 as an input device, and the mobile terminal 100 also includes a display unit 102 , a speaker 103 , a microphone 104 and the like. [0003] In addition, input keys, function keys, selection keys, and decision keys are arranged on the operation unit 101 of the mobile terminal. The input keys are 12 types of keys consisting of number keys from 0 to 9, * key, and # key. The function key is a key for invoking functions such as "clear", "memo", and "quiet mode". When the user performs operations, the general method is to hold the mobile terminal with one...

Problems solved by technology

Like this, if want to be able to input Japanese alphabet or English alphanumeric etc. in the limited area on the numerical keypad of mobile phone, then a key will correspond to quite a lot of characters, under the situation that a key corresponds to quite a lot of characters, can cause very much A small difference in the direction of movement causes the user to select a character that he did not intend to select, resulting in reduced operability

[0016] And, in the above-mentioned situation, the user must pay attention to every slight change of the moving direction when inputting in order not to input wrong characters, which will bring mental and physical fatigue to the user.
