Abstract:
An information processing apparatus including a display device for displaying images in relation to the predetermined processes among a plurality of different processes and a touch panel device for outputting a depressing position signal indicating the depressing position on the touch panel and a depressing pressure signal indicating the depressing pressure on the touch panel in view of respectively executing a plurality of processes explained above depending on said depressing position signal and said depressing pressure signal, comprising:comparing means for comparing said depressing pressure indicated by said depressing pressure signal from said touch panel device with the reference depressing pressure; propagating means for propagating a surface elastic wave, and then comparing successively generated surface elastic waves to detect said depressing position by a change in said surface elastic wave; monitoring means for monitoring change of the depressing position indicated by said depressing position signal depending on said depressing position signal from said touch panel device; processing means for selecting and processing the process to be executed among a plurality of said processes depending on an output of said touch panel device, an output of said comparing means and an output of said monitoring means; and display control means for modifying said display image displayed on said display device depending on an output of said touch panel device, an output of said monitoring means and said process selected by said processing means.
