Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vibrations are generated continuously during input operations, then haptic feedback is enhanced, but energy consumption increases
Solution Approach 1:
The vibration control unit generates vibrations periodically based on the moving locus of the pen-shaped input device rather than continuously. By sectionalizing the moving locus and generating vibrations at specific intervals corresponding to different sections, the system provides haptic feedback only when needed, reducing energy consumption while maintaining feedback quality.
Solution Approach 2:
The vibration generation is dynamically adjusted based on the real-time position and movement of the pen-shaped input device. The vibration control unit determines whether to generate vibrations by comparing the current position with the moving locus, making the vibration generation adaptive and dynamic rather than static or continuous.
2Ease of operation
If vibration control is added to enhance usability, then user experience is improved, but device complexity increases
Solution Approach 1:
The vibration control unit serves multiple functions: it generates vibrations for haptic feedback, provides tactile guidance for the moving locus, and enhances user awareness of the input device position. By making the vibration control unit multi-functional, the patent avoids adding separate systems for each function, thereby limiting the increase in device complexity.
Solution Approach 2:
The system implements feedback by generating vibrations based on the detected position of the pen-shaped input device relative to the moving locus. This feedback mechanism helps users understand their input actions and the system's response, improving usability without requiring complex additional hardware.

AI summary
An information processing system is configured by including a coordinates detector which is configured to detect coordinates which correspond to a position of an operational object surface with which a pen-shaped input device is in contact and a controller which is configured to so control as to switch ON/OFF of vibrations which are generated from the pen-shaped input device in accordance with an interval pattern which is obtained by sectionalizing a moving locus of the coordinates which are detected by the coordinates detector in a case where the pen-shaped input device moves in contact with the operational object surface in accordance with a predetermined distance.
