Mobile Device Mutual Navigation with Sensory Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device navigation systems do not provide a secure method for users to navigate towards and identify each other's devices along a mutual navigation route, especially in crowded or unfamiliar environments, lacking personal security features.
Innovation Solution
A method and system that generates a mutual navigation route between two mobile devices and initiates sensory cues when they reach a predetermined threshold distance, using existing GPS, wireless communication, and inertial navigation capabilities to ensure secure meetup without prior communication history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users navigate to meet in crowded or unfamiliar environments, then navigation capability is improved, but personal security and device identification reliability deteriorate
Solution Approach 1:
The patent applies visual sensory cues (display images, colors, and visual indicators) on mobile device screens to enable users to identify counterpart devices during navigation. The system displays distinctive visual markers that allow users to locate and recognize the correct device among multiple devices in crowded environments, thereby resolving the contradiction between navigation ease and identification reliability.
Solution Approach 2:
The patent employs auditory sensory cues (audio tones, vibrations, and sound signals) to provide additional identification mechanisms. When devices reach proximity or specific navigation milestones, audio feedback helps users confirm the presence and identity of counterpart devices, enhancing reliability in environments where visual cues alone may be insufficient.
2Reliability
If sensory cues are provided to identify counterpart devices, then personal security is improved, but device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional capabilities of mobile devices (display screens, audio speakers, vibration motors, GPS receivers) to provide security features. By using already-present hardware components for dual purposes (navigation and security identification), the system enhances personal security without significantly increasing device complexity.
Solution Approach 2:
The system utilizes the mobile device's own built-in sensors and output mechanisms to provide identification cues. Each device independently generates and displays visual and auditory cues using its own resources, eliminating the need for additional external hardware or complex centralized control systems.

AI summary
A mutual navigation route is generated from a first to a second mobile devices, the mutual navigation route defining a route from one of the first and second mobile devices to another of the mobile devices. Responsive to determining that a predetermined threshold distance between the first and second mobile devices is reached, generating a first sensory cue at the first mobile device and a second sensory cue at the second mobile device, the first and second sensory cues being provided in counterpart.
