Wearable Vibration Feedback for Operation Confirmation in Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable apparatuses face challenges in notifying users of operations in noisy environments or when worn in positions that make it difficult for users to observe the device with their naked eyes.
Innovation Solution
The wearable apparatus incorporates a vibration motor that provides tactile feedback to the user, allowing them to confirm operations such as powering on/off or taking pictures without needing to visually check the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If prompt light is used to notify users, then users can observe the state of the wearable apparatus, but users cannot directly feel it in noisy environments and some scenes are not convenient to use
Solution Approach 1:
The patent introduces a vibration motor as an intermediary notification mechanism that translates operational states into tactile vibrations. This mediator bypasses the limitations of visual (prompt light) and auditory (prompt sound) channels, providing a reliable notification method that works effectively in noisy environments and when the device is worn in positions difficult to observe.
2Loss of information
If prompt sound is used to notify users, then users can receive notifications, but in a noisy environment the prompt effect is not good and users cannot directly feel it
Solution Approach 1:
The patent replaces the acoustic notification system (prompt sound) with a mechanical vibration system. The vibration motor generates tactile feedback that users can directly feel through the wearable device, substituting the acoustic channel with a mechanical channel that is not affected by environmental noise.
3Ease of operation
If the wearable apparatus is worn on the user's head and chest, then it can be carried with the user, but it is often difficult for the user to observe the state of the wearable apparatus
Solution Approach 1:
The patent transitions the notification modality from visual (two-dimensional screen display) to tactile (one-dimensional vibration feedback). This dimensional change allows users to perceive device states through touch rather than sight, enabling effective notification even when the device is worn in positions that are difficult to observe visually.
4Ease of operation
If vibration motor is used to provide tactile feedback, then users can confirm operations without visual check, but the device complexity increases
Solution Approach 1:
The patent integrates the vibration motor into the existing wearable device structure, allowing it to serve multiple functions: providing tactile feedback for operation confirmation, indicating device status, and alerting users to important events. This multi-functionality approach minimizes the impact on device complexity while maximizing the utility of the vibration feedback mechanism.
