Abstract
There is provided a matless step detection unit for a game improved in portability, storability, and detection accuracy. The detection unit uses sensors to detect a step in a dance game in a non-contact manner, and delivers information on the detected step to a network, thereby enabling a dance game to be enjoyed on a smart device or a game terminal. A step information reception unit having a rectangular frame structure enables a step detection game to be played in various forms, by a structure in which coupling portions of sides are coupled by parts or contacts, for example, hinges.
Claims8
A step detection unit, comprising:
- step information transmission units individually mounted on respective legs of a player, each configured to measure, by a built-in sensor, acceleration, vibration, or impact generated when the player steps and a foot contacts a floor surface or a ground surface, and configured to transmit a step detection signal, the step detection signal is light in a case where a result of the measurement is a level corresponding to a step;
- and a step information reception unit including sensing regions for detecting spaces extending within certain ranges from one or more sensors provided on sides of an outer peripheral portion of a polygonal housing disposed on the floor surface or the ground surface, wherein when the player steps in an area corresponding to any of the sensing regions, the step information transmission unit mounted on the stepping leg of the player transmits the step detection signal, when the step detection signal is detected in the sensing region on the outer peripheral portion of the step information reception unit, it is detected that the player steps, and the step detection unit includes a communication means configured to transmit step detection information including a detection result of the step detection signal and a position of a step detection area, to a game device through a network by using a communication function incorporated in the unit.
A step detection unit comprising:
- a step information reception unit having a polygonal housing disposed on a floor surface or a ground surface, the housing including one or more sensors provided on each side of an outer peripheral portion of the housing to define sensing regions extending within predetermine ranges from the sensors;
- wherein a lens is mounted on each of the sensors provided on the sides of the outer peripheral portion of the step information reception unit to converge the sensing region in a vertical direction and to form the sensing region into a linear shape as viewed from a side, in an area where the player steps;
- and wherein the lens is configured to narrow the sensing region in the vertical direction such that the sensing region is physically limited to a region adjacent to the floor surface or the ground surface, thereby preventing detection of a foot that is not in contact with the floor surface or the ground surface.
