Pinned Display Area for Touch Input Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with touch panels, such as electronic whiteboards, face limitations in managing display area, requiring users to swipe the screen to view objects not currently displayed, disrupting discussions and workflows.
Innovation Solution
The implementation of a pinning layer that allows users to select and retain objects within the display area, enabling them to move the display area without changing the position of pinned objects, using techniques like holding objects with an input device, pressing buttons, or enclosing areas with strokes, and sharing these operations between connected display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users swipe the screen to view objects not currently displayed, then all objects can be accessed, but discussion continuity is disrupted and workflow is interrupted
Solution Approach 1:
The display area is segmented into a fixed display region and a movable display region. The fixed display region retains important objects (selected by users through holding, button pressing, or stroke enclosing operations) stationary while the movable region can be swiped to access other objects. This segmentation allows simultaneous object accessibility and discussion continuity.
Solution Approach 2:
The patent introduces a spatial dimension solution by creating a layered display structure where pinned objects exist in a fixed dimensional space while other objects can be accessed through swiping in another dimensional direction. This allows users to access additional objects without moving the pinned objects, resolving the contradiction between accessibility and continuity.
2Adaptability or versatility
If the display area is moved to show different objects, then more content can be viewed, but retained objects may be lost or moved
Solution Approach 1:
Users perform preliminary actions (holding objects with input device, pressing buttons, or enclosing with strokes) to designate which objects should be retained before moving the display area. This preliminary selection ensures that important objects are protected from being lost or moved when the display area shifts, maintaining both display flexibility and object retention reliability.
Solution Approach 2:
The patent introduces a pinning mechanism as an intermediary between the display area and objects. This intermediary layer allows the display area to move freely while pinned objects remain fixed through the pinning relationship, decoupling the movement of the display area from the position of retained objects.
3Adaptability or versatility
If multiple display devices are connected, then content sharing is enabled, but system complexity increases
Solution Approach 1:
The patent implements content sharing through copying the pinned objects and display state information between connected display devices. When an object is pinned on one device, the same pinned state is replicated on connected devices, allowing seamless content sharing without requiring complex multi-device synchronization protocols. This copying approach enables content sharing while keeping system complexity manageable.

AI summary
A display apparatus includes circuitry to display a display area at a first location. The display area is a portion of an input receiving area for receiving hand drafted input. The circuitry selects an object to be retained in the display area based on a user operation, receives an operation of moving the display area to a second location different from the first location in the input receiving area, and displays the display area in which the object is retained at the second location according to the operation of moving the display area.
