Wearable Haptic Navigation Interface Using Multi-Tactile Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation devices and apps primarily rely on visual and auditory cues for route guidance, which can be inefficient and increase the risk of accidents, especially when users are engaged in conversations or in situations where visual attention is difficult to maintain, such as driving, exercising, or in crowded environments.
Innovation Solution
A tactile information supply device that converts external message information into tactile signals, using a receiver, controller, and operator units to provide vibration, brushing, constriction, beating, pressing, tapping, and tilting sensations, allowing users to receive navigation and alert information through touch, even when visual and auditory attention is diverted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual and auditory information is used for route guidance, then information can be transmitted clearly, but user safety deteriorates when users are engaged in conversations or driving
Solution Approach 1:
The patent segments the information transmission channel by separating visual/auditory information from tactile information. Different types of notifications (route guidance, messages, alarms) are transmitted through dedicated tactile patterns (vibration, brushing, constriction, beating, pressing, tapping, tilting), allowing users to receive information without diverting visual or auditory attention from safety-critical tasks.
2Loss of information
If visual display is used for information transmission, then information can be presented in detail, but ease of operation deteriorates when users are exercising or in crowded environments
Solution Approach 1:
The patent merges the tactile feedback mechanism with the information transmission function. The operator unit, which can be worn on the body, combines multiple tactile stimulation capabilities (vibration, brushing, constriction, beating, pressing, tapping, tilting) into a single device that delivers comprehensive information feedback without requiring visual engagement, thereby improving ease of operation during physical activities or in crowded environments.
