Display Control Using User And Reference Footstep Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for portable devices fail to provide intuitive and comprehensive feedback on the comparison of user's walking or running state with a reference, making it difficult for users to understand their performance relative to a standard.
Innovation Solution
A display control method that generates user marks and reference marks on a display to represent foot landing positions based on measured step lengths, allowing real-time comparison with a predetermined reference step length, accompanied by animations to enhance user understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If measured data on running or walking is processed to provide detailed information, then the quantity of information is improved, but the intuitiveness of feedback deteriorates
Solution Approach 1:
The feedback information is segmented into two distinct types: user marks representing the user's actual foot landing positions, and reference marks representing a reference person's foot landing positions. This segmentation allows comprehensive data presentation while maintaining intuitiveness through visual distinction and spatial arrangement.
Solution Approach 2:
The patent transforms one-dimensional step count data into a two-dimensional spatial representation on the display screen. User marks and reference marks are positioned along a distance axis, creating a visual timeline that intuitively shows progression and comparison over distance rather than just time or step count.
2Measurement precision
If step-by-step detailed marks are displayed, then measurement precision is improved, but device complexity deteriorates
Solution Approach 1:
The patent uses simple graphical mark symbols to represent complex foot landing position data. Each mark is a simplified copy or representation of the actual measured position, preserving the essential information while avoiding the complexity of displaying raw coordinate data or detailed gait analysis.
Solution Approach 2:
Multiple data elements (position, timing, step number) are merged into a single visual mark representation. Each mark consolidates multiple measurement parameters into one graphical element that can be quickly perceived and compared, reducing display complexity while maintaining measurement precision.

AI summary
Provided is a display control method for a display control device including a processor and a storage. The method includes generating first display data for a display to display user marks at intervals so as to be added one by one as a time elapses from a timing. The intervals each correspond to a user's step length of a user obtained based on measured data on running or walking of the user. The user marks each represent a position where a foot of the user lands by one step. The method further includes generating second display data for the display to display reference marks at intervals so as to be added one by one as the time elapses. The intervals each correspond to a predetermined reference step length. The reference marks each represent a position where a reference foot lands by one step.
