Touch Panel Gesture Event Selection for Mixed Multi-Single Mode Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for multi-touch capable touch panels in data processing apparatuses, such as MFPs, struggle to seamlessly switch between multi-touch and single-touch operations within a single view, especially when the view includes areas for both types of interactions, leading to inefficiencies in user operation handling.
Innovation Solution
A data processing apparatus with a control portion that executes a browsing program, generates mouse events, and determines gesture events based on position detection, allowing for the selection of appropriate events based on their type and location within embedded areas, enabling proper handling of multi-touch and single-touch operations within a unified interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conventional method switches between multi-touch and single-touch modes depending on the view, then application programs can be executed on the touch panel, but a single view containing both multi-touch and single-touch areas cannot be properly handled
Solution Approach 1:
The touch panel display is divided into multiple touch operation areas, each with its own touch mode attribute (single-touch or multi-touch). The control portion segments the processing of touch events by area, determining the appropriate operation mode based on which specific area receives the touch input, rather than switching modes globally for the entire display.
Solution Approach 2:
Different regions of the display panel are assigned different touch operation qualities - some areas accept only single-touch operations while others accept multi-touch operations. The system identifies the touched area's specific properties and applies the corresponding operation mode locally, allowing a single view to contain both types of interaction areas with their respective touch capabilities.
2Ease of operation
If the touch panel accepts multi-touch operations, then user interaction capability is enhanced, but handling becomes complex when different areas require different operation types
Solution Approach 1:
The system performs preliminary configuration by assigning touch mode attributes to each operation area before touch events occur. When a touch event is detected, the control portion quickly identifies which pre-defined area was touched and retrieves the predetermined operation mode for that area, avoiding complex real-time analysis of whether the user intends single-touch or multi-touch operation.
3Adaptability or versatility
If application programs are installed on the MFP, then customization capability is improved, but operation mode switching between applications becomes necessary and complex
Solution Approach 1:
The control portion implements a universal touch event processing mechanism that simultaneously supports both single-touch and multi-touch operation modes within the same application and across different applications. Each operation area is configured with its own touch mode attributes, allowing multiple applications to coexist with their respective touch requirements without requiring global mode switching, thereby eliminating time loss during application transitions.

AI summary
A data processing apparatus includes a browsing portion to execute a process of the type corresponding to a gesture event, a mouse event generating portion to generate a mouse event including positional information indicating the position detected by a position detecting portion, and a gesture event determining portion to determine one of gesture events on the basis of the mouse event(s). The browsing portion includes a display image generating portion operable, when content includes a description for displaying an embedded image generated as an application program is executed, to generate a display image with the embedded image arranged in an embedded area, and a selecting portion operable, when the position indicated by one of the mouse event(s) from which the gesture event has been determined falls within the embedded area, to select either the gesture event or the mouse event(s) on the basis of the type of the gesture event.
