Touchscreen Verification Code Input via Element Position Sensing

The patent replaces traditional mechanical keyboard input with touch screen interaction. Users directly touch verification code elements displayed on the screen rather than typing characters, substituting mechanical keyboard input with graphical touch interaction. This resolves the contradiction by maintaining security through verified element selection while dramatically improving input convenience on touch devices.

The patent creates visual copies of verification code elements (geometric shapes, colors, patterns) that users can directly select by touching the display. Instead of requiring users to type characters that represent the verification code, the system presents visual representations that can be directly manipulated through touch, maintaining security verification while improving user experience.

The patent divides the verification code into distinct geometric elements (shapes, colors, patterns) arranged in specific spatial configurations. Each element is segmented and independently identifiable, allowing users to accurately select required elements without confusion from stacked texts or interfering pixels. This segmentation maintains security through complex element relationships while improving input accuracy.

The patent uses color variations and geometric shape variations as the basis for verification code elements. Instead of relying on text characters that can be obscured by interfering pixels, the system uses distinct visual properties (color, shape, position) that remain clearly recognizable. Users select elements based on their visual characteristics rather than decoding text, improving accuracy while maintaining security.
