Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face inefficiencies when annotating or performing operations on larger touch screens, as direct cursor annotation can be cumbersome and inefficient.

Innovation Solution

An intelligent interaction method that allows users to display a zoomed window of a multimedia file on a touch screen, enabling annotation within the smaller zoomed window while maintaining the current window, and updating the current window with annotations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a larger touch screen is used to display multimedia content, then the display area and visibility are improved, but the ease of operation and annotation efficiency deteriorate

Engineering Contradiction:

Improvedisplay areaVSAvoidannotation efficiency

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The patent divides the interaction space by introducing a virtual zoomed window that segments the annotation task from the full display area. Users can annotate within this focused virtual region while the rest of the screen remains visible, thus maintaining large display area while improving annotation precision and ease of operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The virtual zoomed window acts as an intermediary between the user and the large display area. It provides a magnified view that facilitates precise annotation operations without requiring the physical touch screen to be small, thereby resolving the contradiction between large display area and ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If direct cursor annotation is used on a large touch screen, then the device complexity is reduced, but the productivity and operation efficiency deteriorate

Engineering Contradiction:

Improvedevice complexityVSAvoidoperation efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent introduces a dynamic virtual zoomed window that can be adjusted and positioned flexibly on the screen. This dynamic interface element allows users to focus on specific regions for annotation while maintaining the simplicity of the underlying device architecture, thus improving operation efficiency without significantly increasing device complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The virtual zoomed window creates a copy or representation of a portion of the display area, allowing users to interact with a magnified view without modifying the physical device structure. This virtual copying approach improves annotation efficiency while keeping the device itself simple.

Inventive Principle:

Principle #26Copying

AI summary

Provided are an intelligent interaction device and method, and a non-transitory computer readable storage medium. The method includes: displaying, on a touch screen, a current window of a multimedia file in a playing state; displaying, in response to an instruction from a user for zooming the current window, a zoomed window of the current window at a first predetermined position of the current window, the zoomed window being smaller than the current window; and displaying, in response to an annotation operation performed by the user for the zoomed window, an annotation in the zoomed window, and updating the current window by displaying the annotation in the current window.
