PROBLEM TO BE SOLVED: To provide a touch panel input device capable of inputting a perfect one-hand written characters in an information terminal device capable of inputting characters and having the touch panel such as a smart phone.SOLUTION: The number of input keys itself in a software key board shown on a touch panel is confined, and key sets, each of which is grouped to a minimum unit such as [a,ka,sa,ta,na], [a,i,u,e,o] or the like, are dynamically switch-over displayed, thereby making the software key board compact, and all the input GUI components are arranged in a range to which an operation finger (thumb) can reach. A core input component is configured to have a circular shape so that a switching operation can be smoothly performed. A direction key component in the software key board is employed for selection of conversion candidates displayed for inputting characters, which are also arranged in a lower layer so as to be superimposed on a keyboard display region. |
