Wearable Movement Indicator for DDR Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Dance Dance Revolution (DDR) systems are limited to a fixed location and can only accommodate a few players at a time, relying on monitors or stage lights to indicate stepping directions, which restricts user interaction and accessibility.
Innovation Solution
A wearable device with a movement indicator, such as a glove, ring, or shoe, equipped with a motion sensor and communication circuit, that transmits movement data to a computing host to provide directional, strength, and distance instructions through lighting or display, allowing users to follow instructions freely and enabling multiple users to participate simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional DDR uses monitor or stage lights to indicate stepping directions, then users can see movement instructions, but the system is restricted to fixed location and limited user capacity
Solution Approach 1:
The patent extracts the movement indication function from the fixed arcade machine environment and relocates it to wearable devices that can be worn anywhere. The movement indicator, motion sensor, and communication circuit are integrated into portable wearable devices, allowing users to receive movement instructions and transmit movement data without being constrained by a fixed location or arcade machine infrastructure.
Solution Approach 2:
The wearable device serves multiple functions: it displays movement instructions through a movement indicator, senses user movements through a motion sensor, transmits data through a communication circuit, and provides feedback. This multi-functional integration enables the system to support multiple users simultaneously in various locations while maintaining comprehensive movement guidance and tracking capabilities.
2Ease of operation
If conventional DDR accommodates only a few players at a fixed location, then the system structure is simple, but user interaction and accessibility are restricted
Solution Approach 1:
Each wearable device independently provides movement indication, movement sensing, and data transmission capabilities. Users simply wear the device and receive movement instructions on the movement indicator, then the motion sensor automatically captures their movements and transmits them to the server. This self-service mechanism eliminates the need for fixed arcade machines and enables unlimited user participation anywhere with network connectivity.
Solution Approach 2:
The patent transitions the system from a single-location, fixed-architecture model to a distributed, multi-location model by moving the indication and sensing functions to wearable devices. This dimensional shift from centralized to distributed architecture enables simultaneous use by multiple users in different locations, fundamentally expanding system capacity and accessibility.
3Adaptability or versatility
If wearable device uses motion sensor to sense movement and transmit data, then user mobility is improved, but device complexity increases
Solution Approach 1:
The patent combines the movement indicator, motion sensor, and communication circuit into a single integrated wearable device. This merging of components reduces the overall system complexity compared to having separate indication devices, sensing devices, and communication systems. The integrated design allows the device to perform multiple functions (display instructions, sense movements, transmit data) while maintaining a compact, wearable form factor that users can comfortably wear during exercise or dance activities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The wearable device system allows users to interact with movement instructions in a flexible and scalable manner, enabling multiple users to play or exercise simultaneously without the constraints of a fixed location, enhancing user experience and accessibility.
Implementation Method 1
A motion sensor is used to sense a movement direction, or including other movement signals such as strength, distance or stepping
Implementation Method 2
The movement indicator allows the user to act according to the movement indication. Therefore, the wearable device with the movement indicator helps the user to exercise, dance or play
Data Source
AI summary
A wearable device with movement indicator, a system and a method for movement indication are provided. The movement indication is implemented on the wearable device. The wearable device receives a movement instruction from a computing host. The movement instruction includes a direction signal that may be accompanied with further instructions such as strength and direction. The instructions are displayed through the movement indicator of the wearable device. A user who wears the wearable device moves in response to a moving instruction. A motion sensor of the wearable device senses a movement signal and obtains a moving direction. Other signals of strength and distance may also be obtained by the motion sensor. After that, the system can score the movement of the wearable device based on the original movement instruction.
