Interactive Drumstick with Motion Prediction for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user interactive systems and devices fail to provide an accurate and realistic experience due to imprecise timing and location mapping of user motions, leading to a less immersive virtual environment.
Innovation Solution
The implementation of interactive devices such as wands and drumsticks equipped with motion detectors, processors, and feedback modules that predict and transmit strike information, determine the relative location of strikes, and provide haptic and audio feedback to accurately simulate striking motions in a virtual environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional user interactive systems transmit strike information after detection, then the system structure is simple, but latency occurs and timing precision deteriorates
Solution Approach 1:
The system performs preliminary action by predicting the strike moment before it actually occurs. The processing module analyzes user movement in real-time and transmits strike information in advance of the actual strike, preemptively compensating for transmission latency and achieving precise timing without requiring complex post-processing corrections.
2Measurement precision
If conventional systems use basic motion detection, then the device complexity is low, but the precision of user action detection deteriorates
Solution Approach 1:
The system implements feedback by continuously monitoring user movement through the processing module and adjusting strike detection based on analyzed motion patterns. This closed-loop approach enhances detection precision by comparing predicted strike moments with actual strikes, allowing the system to refine its measurements and maintain high accuracy without requiring overly complex hardware.
3Reliability
If conventional systems map user motion location imprecisely, then the system is easier to implement, but the realism of virtual environment deteriorates
Solution Approach 1:
The system applies preliminary action to location mapping by determining the relative location of strikes in advance and pairing them with preselected virtual objects. This proactive approach ensures accurate spatial correspondence between physical user actions and virtual environment interactions, enhancing realism by establishing correct object associations before the strike occurs rather than attempting to correct mismatches afterward.

AI summary
Systems, methods, and devices for providing interactive striking objects (e.g., drumsticks) and performing actions in response to striking motions of the striking objects are disclosed. In some embodiments, the systems and methods provide an interactive drumstick, which includes a lighting display located at a tip portion of the interactive drumstick, a motion detector contained at least partially within the drumstick, a processor and memory contained at least partially within the drumstick, and an interactive system stored within the memory of the drumstick. The interactive system includes a striking motion module that determines striking motions of the drumstick with respect to a virtual percussion instrument based on accessing information measured by the motion detector, and a display module that causes the lighting display to present a certain type of illumination based on the striking motions determined by the striking motion module.
