Abstract: Each time stepping motion of a player by a stepper 1 is detected, one firework object 214 appears on a television monitor 100 and then disappears. Each a predetermined number of times of the stepping motion of the player is detected, a more spectacular firework object than that of one step is displayed. If the player performs the stepping motion by frequency as a quota shown in a quota display section 212, this screen is finished.

Abstract: A retroreflective sheet 32 is provided on the inner surface of a transparent member 44. A belt 40 is attached to the transparent member 44 along the bottom surface thereof in the form of an annular member. An operator inserts middle and annular fingers into the belt 40 in order that the transparent member 44 is located on the palm of the hand. The information processing apparatus 1 can determine an input operation when a hand is opened so that the image of the retroreflective sheet 32 is captured, and determine a non-input operation when a hand is closed so that the image of the retroreflective sheet 32 is not captured.

Abstract: It is an object to provide a thermal-transfer recording medium and its thermal-transfer recording method whereby it is possible to perform good thermal transfer to a durable transfer medium such as plastic film etc., and the transferred image is excellent in resistance to mechanical abrasion, and whereby color reproducibility is excellent when plural colors of thermal transferred inks are printed in layers. A thermal-transfer ink layer is provided which at least presents the visco-elastic characteristics that tan.delta. is of 1 or more and the complex dynamic viscosity falls within 100 to 40,000 Pa.s in the viscoelasticity measurement with a frequency of 1 Hz in the linear viscoelastic region of temperature from 100 to 150.degree. C. Alternatively, a thermal-transfer ink layer containing a coloring matter and a thermo-fusing resin is provided on a support, and the thermo-fusing resin presents the visco-elastic characteristics that tan.delta. is of 1.
