Circular Dialing Keypad for Smart Watch Mistrigger Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart watches with phone functions experience poor user experiences due to mistriggers during the dialing process on their small screens, leading to inefficient dialing operations.
Innovation Solution
A method for implementing a dialing keypad on a touch screen that configures dialing controls with numerical, display, and angle information, arranging them evenly on a circular display area, and responding to user interactions to rotate controls and input numbers through sliding operations, thereby reducing mistriggers and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a common Sudoku arrangement dialing keypad is used on a smart watch with a small screen, then the dialing controls can be displayed, but mistriggers easily occur resulting in poor user experiences
Solution Approach 1:
The patent transforms the traditional linear Sudoku arrangement into a circular arrangement where dialing controls are evenly distributed along a circular path. This curved layout optimizes the use of small screen space while increasing the distance between adjacent controls, thereby reducing mistriggers and improving dialing accuracy on smart watch displays.
Solution Approach 2:
The patent transitions from a two-dimensional grid layout to a one-dimensional circular arrangement. By organizing dialing controls along a circular path rather than in a rectangular grid, the design maximizes screen space utilization and provides better spacing between controls, reducing accidental touches while maintaining all necessary dialing functions.
2Area of moving object
If the screen size is reduced for smart watch form factor, then the device becomes more wearable, but the dialing controls become harder to operate accurately
Solution Approach 1:
The circular arrangement of dialing controls along a curved path allows efficient use of the limited screen area while maintaining adequate spacing between controls. This curved layout prevents controls from being too crowded, ensuring accurate operation despite the small screen size typical of wearable devices.
Solution Approach 2:
The patent implements a dynamic sliding operation where users can swipe across the circular dialing controls to select numbers. This dynamic interaction method adapts to the small screen size by allowing continuous movement across controls rather than requiring precise static tapping, thereby maintaining operation precision on compact displays.

AI summary
A method for realizing a dialing keypad of a touch screen, and smart watch. The method comprises: acquiring size information of the touch screen, and configuring a circular display region of the touch screen by using a center of the touch screen as an origin and a preset length as a radius (S10); configuring attributes of each dialing control of the dialing keypad, the attributes of the dialing controls comprising numeral information, display information and angle information of the dialing controls (S20); uniformly arranging, according to the acquired size information of the touch screen and the angle information of each dialing control of the dialing keypad, all dialing controls of the dialing keypad on a periphery of an edge of the circular display region (S30); and displaying, according to the numeral information and the display information of each dialing control of the dialing keypad, all dialing controls of the dialing keypad on the periphery of the edge of the circular display region of the touch screen (S40). The method effectively reduces a mistaken touch operation in a dialing process.
