Abstract: There is provided an information processing apparatus including a storage unit for storing a transition frequency database storing transition frequency information representing a frequency of a state transition of a display content displayed on a display screen from a display state displaying the display content to another display state, and a cache control unit for predicting the another display state to which a transition may occur based on the transition frequency database and the display content displayed on the display screen, and preparing a resource needed by the another predicted display state before the transition occurs.

Abstract: A mobile terminal device input confirmation support system includes: an information storage unit for storing groups of information, the groups being assigned to a plurality of keys, respectively, each group including information pieces, the information piece of each group being sequentially changed in a cyclic manner every pressing the corresponding key; an information position storage unit for storing positions to identify the information pieces of the respective groups stored in the information storage unit; a reaction unit for performing reaction corresponding to each of the positions stored in the information position storage unit; and an input confirmation support unit for reading a position corresponding to input information to allow the reaction unit to perform reaction corresponding to the position when one key is pressed to input the information.
