Abstract: The improved jump ropes devices described herein generally include a source of rhythmic sound, a sensor for determining the motion of the jump rope, and a visual output (e.g., feedback) for indicating how well a user is moving or jumping in time to the rhythmic component of the sound. The device may also include a controller for receiving input from the source of rhythmic sound and the sensor, and controlling the visual output. Methods of using the devices are also described.

Abstract: Described herein is a game and game system including one or more user motion tracking devices. In some embodiments, a heart rate sensor is also used to monitor the user.

Abstract: The invention described herein provides game systems or devices that typically include a projector for projecting a plurality of images or colors at different positions in space, a source of music, and a controller configured to coordinate the presentation of the images or colors with the music.

Abstract: Described herein are games and game systems including a text messaging phone keypad foot mat. The phone keypad foot mat typically includes regions similar to the buttons of an enlarged telephone keypad. A user can step on these input regions (“buttons” or “keys”) to type a text. Thus, a player “types” a text message by stepping or dancing on the keyboard foot mat similar to the way that a text message may be typed by hand on a telephone keypad (e.g., sending a text message from a cell phone). Various games can be played using the devices, systems and methods described herein.
