Display Control Device for Electronic Metronome Beat Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic metronomes, the movement range of light can be difficult to perceive due to the design of the display section, making it challenging for users to grasp the beat timing.
Innovation Solution
A display control device with a controller that changes the display position of light to repeatedly reciprocate on a predetermined track according to the beat timing, and stops the light at positions corresponding to both ends of the track during a certain period including the beat timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the light moves continuously without stopping, then the beat timing becomes harder to perceive, but stopping the light may interrupt the visual continuity
Solution Approach 1:
The light is made to stop periodically at both ends of the track during a certain period including the beat timing, creating a periodic pause that highlights the beat moment while maintaining overall visual continuity through the reciprocating motion pattern
2Area of stationary object
If the movement range of light is small, then the display section design is compact, but the user cannot easily perceive how far the light moves
Solution Approach 1:
The light changes its state from moving to stopping, creating a visual contrast that emphasizes the movement range and makes it more perceivable to users, effectively using state change rather than color change to highlight the display range

AI summary
A display control device 1 includes: a controller 10S that controls a light source unit 162, wherein the controller 10S: changes a display position of light such that the light emitted from the light source unit 162 and projected on a display section 166 repeatedly reciprocates on a predetermined track on the display section 166 according to a beat timing, and stops the display position of the light at positions corresponding to both ends of the track during a certain period including the beat timing.
