Information Processing Device Distance Interaction Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices struggle to accurately perform additional manipulations, such as release manipulations, at a designated pointing position, especially when the user is apart from the display plane, leading to difficulties in executing user intentions.
Innovation Solution
An information processing device with a determination unit that assesses the pause of a manipulation position specified through pointing to a display plane and issues corresponding commands when the execution of the manipulation is determined, allowing for the execution of additional manipulations that match user intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pointing manipulation is performed at a position apart from the display plane, then the user can interact with the device from a distance, but it becomes difficult to execute additional manipulations such as release manipulations at the designated position
Solution Approach 1:
The patent introduces a cursor as an intermediary element that bridges the gap between the user's pointing manipulation from a distance and the display plane. The cursor is positioned at the designated location on the display plane and serves as a mediator that enables additional manipulations (such as release operations) to be executed accurately without requiring the user to be in direct contact with the display surface. This resolves the contradiction by allowing distance interaction while maintaining manipulation execution accuracy through the mediating cursor object.
2Device complexity
If the system recognizes only basic pointing manipulations, then the recognition process is simple, but additional manipulations that match user intentions cannot be executed
Solution Approach 1:
The patent applies preliminary action by establishing a cursor at the designated position before the additional manipulation is executed. The cursor is positioned in advance based on the pointing manipulation, and then serves as the target for subsequent additional manipulations (such as release operations). This preliminary positioning enables the system to recognize and execute diverse manipulation types without increasing the complexity of the recognition process itself, as the cursor already establishes the context for what manipulations are expected.
3Ease of operation
If the manipulating body is positioned apart from the display plane, then user comfort is improved, but the precision of specifying the manipulation position decreases
Solution Approach 1:
The patent uses the cursor as a copy or representation of the user's pointing intent on the display plane. When the user performs a pointing manipulation from a distance, the system creates a cursor at the designated position that accurately represents where the user intends to interact. This copying mechanism allows the user to maintain a comfortable distance while the cursor precisely marks the manipulation position on the display plane, effectively transferring the pointing accuracy requirement from the physical manipulating body to the digital cursor representation.

AI summary
There is provided an information processing device including a determination unit configured to perform determination of execution or non-execution of a manipulation based on a pause of a manipulation position specified through a manipulation of pointing to a display plane using a manipulating body at a position apart from the display plane, and a control unit configured to issue a command corresponding to the manipulation when the determination unit determines execution of the manipulation.
