Handheld Game Console Step Count Correlation Value Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld information processing devices require external communication to utilize step count data for services or games, making it inconvenient to use measured step counts across multiple applications.
Innovation Solution
A handheld information processing apparatus with a memory unit storing multiple applications, featuring a step count measurer, accumulator, and utilizer, which converts and accumulates step counts into a correlation value, allowing seamless use across applications without the need for external communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If step count data is transmitted to another device via communication to utilize services, then services can be provided, but the system becomes complex and requires external communication infrastructure
Solution Approach 1:
The handheld information processing apparatus integrates multiple functions including step count measurement, correlation value accumulation, and multiple applications (game application, utility application) within a single device. This eliminates the need for external communication devices while maintaining service utilization capability through the shared data area that allows different applications to access and utilize the accumulated step count correlation values.
2Adaptability or versatility
If step count data is transmitted to a server via communication to play games, then game services can be provided, but the system requires external communication and cannot function offline
Solution Approach 1:
The handheld information processing apparatus performs all game-related processing locally without requiring external server communication. The game application reads step count correlation values from the shared data area, determines game content based on these values, and executes games entirely within the device. This self-service capability allows the system to function offline while maintaining full game service capability.
3Productivity
If multiple applications share step count data, then data utilization efficiency improves, but data security and access control become problematic
Solution Approach 1:
The memory unit is segmented into a shared data area and application-dedicated data areas. The shared data area stores step count correlation values that can be accessed by all applications, enabling efficient data utilization. Meanwhile, the application-dedicated data areas provide isolated storage for each application's specific data, ensuring that applications can only access and modify their own dedicated data while reading from the shared area. This segmentation maintains both data utilization efficiency and access control reliability.

AI summary
A game apparatus as a handheld information processing apparatus includes a CPU, and when the game apparatus is closed, the CPU shifts to a sleep mode. When a user carries the game apparatus in the sleep mode, a micon measures step counts according to a magnitude of accelerations indicated by acceleration data from an acceleration sensor. When a main power of the game apparatus is turned on to display a main menu screen, the step counts are converted into earned coins, for example. In each of a plurality of applications to be executed by the game apparatus, a special item is purchased, or game playing on a special course is permitted by utilizing the earned coins.
