Wearable Device Rim Touch Sensor Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices like smart watches face inconvenience due to their small display screens, where touch inputs often obscure the screen and are not intuitive, necessitating a more convenient user interface.
Innovation Solution
A wearable electronic device with a touch display and a rim surrounding the display, equipped with a rim touch sensor, allowing users to control the device through rim touches without covering the screen, utilizing attributes like touch position, duration, rotating direction, pressure, and shear force direction to generate control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen is used for user interface control, then the device can be controlled, but the small screen is obscured by the user's finger or touch pen
Solution Approach 1:
The patent extends the touch interface from the two-dimensional display surface to the three-dimensional rim structure. By placing touch sensors on the rim, users can interact with the device using their fingers on the side surface rather than covering the display screen, thus maintaining full visibility of the screen while enabling touch control through a different spatial dimension.
Solution Approach 2:
The patent divides the touch interface into separate functional zones: the display screen for visual information and the rim structure for touch input. This segmentation allows the touch control function to be isolated from the display area, enabling users to operate the device without obscuring the screen.
2Volume of moving object
If a small display screen is used in a wearable device, then the device fits comfortably on the user's wrist, but the screen is easily hidden by touch inputs
Solution Approach 1:
The patent moves the touch input interface to the rim, creating a three-dimensional interaction space around the small display. This allows users to operate the device with their fingers on the rim surface rather than covering the small screen, maintaining both the compact size and operational convenience.
Solution Approach 2:
The rim acts as an intermediary structure between the user's finger and the small display screen. Instead of directly touching the small screen which would obscure it, users interact with the rim as a mediator that translates their input into control signals for the device.

AI summary
The described technology relates to a wearable electronic device. The wearable electronic device may include a touch display, a rim surrounding the touch display, a rim touch sensor disposed on at least a portion of the rim, a band portion that allows the wearable electronic device to be worn on a user's wrist, and a control unit configured to receive a rim touch on the rim through the rim touch sensor and generate a control signal for controlling the wearable electronic device based on at least one of attributes of the rim touch.
