Wearable Input Threshold Control for Out-of-View False Touches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices face challenges in accurately distinguishing intentional user inputs from unintentional ones when the display is outside the user's field of view, leading to potential malfunctions and unnecessary power consumption.
Innovation Solution
A wearable device equipped with sensors to detect wearing and inertial information adjusts the input determination threshold based on the display's orientation relative to the user's field of view, changing the threshold value when the display is outside the view range to prevent unintended inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the input determination threshold is kept at a low value to ensure responsiveness, then the device responds quickly to user inputs, but false activations increase when the display is outside the user's field of view
Solution Approach 1:
The patent applies dynamics by making the input determination threshold adjustable rather than fixed. The threshold dynamically changes based on the display's orientation relative to the user's field of view. When the display is within the field of view, a first threshold value is used for responsive input detection. When the display is outside the field of view, a second higher threshold value is used to prevent false activations. This dynamic adjustment resolves the contradiction between maintaining fast response and ensuring input accuracy.
Solution Approach 2:
The patent changes the parameter of the input determination threshold based on the display orientation parameter. By monitoring whether the display is within or outside the user's field of view and adjusting the threshold parameter accordingly, the system achieves both fast response when needed and high accuracy when the display is not visible, resolving the contradiction between speed and reliability.
2Reliability
If the input determination threshold is increased to prevent false activations, then input accuracy improves, but legitimate inputs may be missed
Solution Approach 1:
The system dynamically adjusts the input determination threshold based on real-time display orientation. When the display is within the field of view, the lower first threshold ensures no legitimate inputs are missed. When the display moves outside the field of view, the threshold increases to the second value to prevent false activations. This dynamic behavior resolves the contradiction between accuracy and input detection capability.
3Ease of operation
If the device continuously monitors input with a low threshold to ensure responsiveness, then user interaction is smooth, but power consumption increases due to processing false activations
Solution Approach 1:
The patent changes the input determination threshold parameter based on display orientation to optimize the balance between ease of operation and power consumption. When the display is visible, the lower threshold maintains smooth user interaction. When the display is not visible, the higher threshold reduces false activations and associated power consumption, resolving the contradiction between operational smoothness and energy efficiency.

AI summary
Provided are a wearable device, a method for controlling an input on the basis of sensing information of the wearable device, and a storage medium. The wearable device includes: an input interface; a first sensor; a second sensor; a display; and at least one processor for: if wearing information of the wearable device is sensed through the first sensor, identifying a direction and an angle in which the display faces, on the basis of inertia information sensed through the second sensor; if the identified direction and angle exceed a preset range, determining that the direction in which the display faces is outside the range of the user's field of view; if it is determined that the direction is outside the range of the user's field of view, changing an input determination threshold value of an input interface from a set first threshold value to a second threshold value greater than the first threshold value; and if a value greater than the input determination threshold value is input through the input interface, performing an operation corresponding to the input.
