Virtual Object Pace Guidance for Wrist-Mounted Exercise Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise support devices, such as GPS-enabled stopwatches, fail to provide an intuitive pace-making function for guiding users to a desired pace during exercises like running, as they require users to constantly read numerical values on a display screen, making it difficult to instantly grasp their exercise status.
Innovation Solution
An exercise support device with a display section showing virtual objects representing a target pace and the user's actual pace, allowing the user to visually compare and intuitively follow their progress, using a wrist-mounted device that calculates and displays movement distances and times to guide the user to set targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerical values are displayed on a display screen during exercise, then measurement precision is improved, but ease of operation deteriorates because users cannot stare at the display screen during exercise and cannot instantaneously grasp the meaning of display content
Solution Approach 1:
The patent creates a visual copy of the exercise progress by displaying a virtual mobile object that replicates the user's movement status. Instead of showing numerical values that require interpretation, the system projects a visual representation (virtual object) that mirrors the user's actual position and progress, making it immediately understandable without requiring the user to read or interpret numbers.
Solution Approach 2:
The patent utilizes visual appearance changes of the virtual mobile object to convey exercise status. The virtual object's position, movement, or visual properties change to reflect the user's exercise progress, providing intuitive visual feedback that can be grasped at a glance without requiring the user to read numerical data on the display screen.
2Loss of information
If various running information is calculated and provided to the user, then information completeness is improved, but device complexity increases and pace making function is not achieved
Solution Approach 1:
The patent extracts only the essential information needed for pace making from the complete set of running data. Instead of processing and displaying all available running information, the system selectively extracts and visualizes the critical elements (virtual object position and movement) that directly support pace making, thereby reducing processing complexity while maintaining the core functional benefit.
Solution Approach 2:
The patent segments the complex running information into a simplified visual representation. By dividing the comprehensive data set into discrete visual elements (the virtual mobile object's position and movement characteristics), the system makes the information manageable and directly applicable to pace making without requiring complex processing of all underlying data.

AI summary
An exercise support device includes: a display section which has a display area where a first object as a virtual mobile object and a second object corresponding to a user are displayed; and a control section which controls display positions of the first object and the second object in the display area. The control section, while the user is moving from a first point to a second point, controls such that the display position of the first object is set to a position corresponding to a first movement distance based on a set target pace and an elapsed time after the user starts movement; and that the display position of the second object is set to a position corresponding to a second movement distance that the user moves from the first point in the elapsed time.
