Touch-Sensitive Keyboard Continuous-Path Gesture and Delete Key Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch-sensitive keyboards on handheld electronic devices lack efficient methods for handling continuous-path and delete key gestures, leading to inefficiencies in typing punctuation symbols and deleting characters, which wastes time and increases power usage.
Innovation Solution
Implementing methods that allow for tap or swipe gestures on the delete key to delete characters or strings of characters, and displaying punctuation symbols during continuous-path gestures, enabling quicker and more seamless interaction without prolonged key presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users tap or press-and-hold the delete key to delete characters one at a time, then deletion function is achieved, but time is wasted and power usage increases
Solution Approach 1:
The patent segments the delete key functionality into multiple gesture types (single tap, double tap, long press) that correspond to different deletion scopes (single character, multiple characters, entire word). This segmentation allows the system to provide appropriate deletion efficiency for different user needs without requiring prolonged key presses.
Solution Approach 2:
The patent implements dynamic response based on the duration and pattern of the press gesture. By detecting whether the user performs a quick tap, double tap, or sustained long press, the system dynamically adjusts the deletion behavior to match user intent, achieving fast deletion without requiring excessively long press durations.
2Productivity
If users tap the function key and search for punctuation symbols on touch-sensitive keyboards, then punctuation input is achieved, but time is wasted and power usage increases
Solution Approach 1:
The patent displays a contextual popup menu with relevant punctuation symbols and characters in advance, before the user needs to input them. This preliminary display of options eliminates the need for users to search through the keyboard layout or access separate function menus, allowing immediate selection and input.
Solution Approach 2:
The patent introduces an intermediary popup menu that appears between the user's typing action and the final character input. This intermediary interface presents punctuation symbols and suggests completions, serving as a mediator that speeds up the input process without requiring users to manually search the keyboard layout.

AI summary
Systems and methods for responding to continuous-path gestures are disclosed. An example method includes: displaying a plurality of keys on a touch-sensitive keyboard; and in response to a continuous-path gesture on the touch-sensitive keyboard in which a contact associated with the continuous-path gesture travels over two or more of the plurality of keys: begin displaying a punctuation symbol key on the touch-sensitive keyboard; and displaying one or more characters based on keys contacted by the contact during the continuous-path gesture.
