Gesture-Based Form Submission on Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for form operations on mobile terminals require users to manually scroll to the bottom to find and click a submit button, which can obstruct form content and complicate user interactions due to screen size limitations, deteriorating the user experience.
Innovation Solution
A method and apparatus that allow users to perform form operations, including submission, through hand gestures detected on the screen, eliminating the need for a visible submit button by matching the gesture trajectory with preset hand gestures and rules, enabling operations at any screen position and combining password verification into a single gesture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a submit button is placed at the bottom of the form, then the form can be submitted, but the button blocks part of the form content and users still need to scroll down
Solution Approach 1:
The submit button is extracted from the visible screen area and replaced with a gesture-based interaction. Users perform a specific gesture (such as swiping upward or drawing a pattern) to trigger form submission, eliminating the need for a visible button that would occupy screen space and block form content.
Solution Approach 2:
A gesture recognition system serves as an intermediary between the user and the form submission function. Instead of directly clicking a button, users perform a gesture that is detected and interpreted by the system, which then triggers the submission action. This intermediary layer eliminates the need for a visible button while maintaining the submission function.
2Area of stationary object
If the screen size is small, then the mobile terminal is portable, but the submit button becomes difficult to find and may block form content
Solution Approach 1:
The submit button functionality is extracted from the physical screen area and implemented through gesture recognition. This allows the full screen area to be used for displaying form content without obstruction, while submission is triggered through a gesture that can be performed anywhere on the screen.
Solution Approach 2:
The interaction paradigm shifts from two-dimensional button clicking to a gesture-based interaction that utilizes motion and trajectory dimensions. Users perform gestures (such as swiping or drawing patterns) that are detected across the screen surface, providing accessible submission without requiring a specific button location.
3Loss of information
If a visible submit button is used, then the submission function is clear, but it obstructs form content and complicates user interaction
Solution Approach 1:
The submit button is completely removed from the visible interface. Form content occupies the full screen area without obstruction. Submission is triggered through a gesture gesture, simplifying the interface while maintaining the submission function.
Solution Approach 2:
The gesture interaction serves multiple functions: it can be used for navigation, selection, and form submission. This universal gesture system eliminates the need for separate buttons while providing clear feedback for all interactions, reducing overall interface complexity.

AI summary
Apparatuses and methods are disclosed for form operation on a mobile terminal. An exemplary method may include detecting an input hand gesture on a screen, and acquiring a trajectory of the input hand gesture. The method may also include matching the acquired trajectory of the input hand gesture with the hand gestures in correspondence in accordance with the hand-gesture comparison rules. The correspondence between hand gestures, hand-gesture comparison rules, and form operations is preset. The method may further include triggering a corresponding form operation if the matching is successful.
