Wearable Computing Device Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable computing devices, such as Head Mounted Displays (HMDs) and Face Mounted Displays (FMDs), fail to continuously provide users with information when the device is placed on the head, as visual information is no longer accessible, and audible information is not readily available.
Innovation Solution
A wearable computing device with a detecting unit to determine its mode of use, a converter to convert visual information to audible information, and an audible information output unit to provide this converted information to the user, ensuring continuous information delivery whether the device is worn on the face or placed on the head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wearable computing device is placed on the user's head, then the user can have hands-free operation and comfort, but visual information is no longer provided to the user
Solution Approach 1:
The system changes the information output parameter from visual to audible based on the detected wearing state. When the device is detected to be on the user's head, the controller automatically switches from displaying visual information to outputting audible information through the speaker, thus maintaining information delivery while accommodating the hands-free wearing state
Solution Approach 2:
The speaker acts as an intermediary device to deliver information to the user in audible form when visual display is not feasible. The converter unit transforms visual information into audible information that can be perceived through the speaker, serving as a mediator between the display unit and the user's perception when the device is worn on the head
2Loss of information
If the wearable computing device is worn on the user's face, then visual information can be provided to the user, but the device structure becomes more complex
Solution Approach 1:
The wearable computing device is designed with multi-functionality to operate in different wearing modes. The same device can be worn on either the face or the head, and the controller automatically adapts the information delivery method based on the detected state, eliminating the need for separate device configurations for different wearing positions
Solution Approach 2:
The device incorporates dynamic adaptation through the detecting unit and controller that automatically adjust the information delivery mode based on the real-time wearing state. The system transitions between visual and audible information output dynamically, allowing the device to respond flexibly to different wearing conditions without requiring manual intervention

AI summary
A wearable computing device receiving at least one of visual information and audible information from an information providing device and providing the received information to a user is disclosed. The wearable computing device includes a detecting unit detecting a state of the wearable computing device and outputting detection information, a controller deciding whether the state of the wearable computing device corresponds to a first mode or a second mode based upon the detection information of the detecting unit, and controlling an output of the visual information and the audible information provided by the information providing device based upon the decided mode, a converter converting the visual information provided by the information providing device to audible information of a voice format when the state corresponds to the second mode, and an audible information output unit providing the audible information converted by the converter to the user.
