Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional input devices (mouse, keyboard, touch pad) are used for operation input, then the device can perform basic input functions, but the operations become unnatural, burdensome, and bothersome in daily life
Solution Approach 1:
The input device is segmented into a ring-shaped main body portion that can be mounted on one finger, with sensors that detect operations from another finger. This segmentation allows the device to be worn unobtrusively while enabling natural finger-based operations without the burden of traditional input devices
Solution Approach 2:
The ring-shaped main body acts as an intermediary between the user's fingers and the information processing device. By mounting the device on one finger and detecting operations from another finger, it mediates the interaction in a way that is more natural and less burdensome than conventional direct hand-to-device interaction
2Ease of operation
If a ring-shaped input device is mounted on one finger to enable natural operations, then ease of operation improves, but the device structure becomes more complex
Solution Approach 1:
The ring-shaped main body serves multiple functions: it acts as a mounting structure on one finger, houses the sensors for detecting operations from another finger, and provides the structural framework for the entire device. This multi-functionality reduces the need for additional components, thereby limiting the increase in device complexity despite the improved intuitiveness of operation
3Measurement precision
If sensors are provided in the ring-shaped main body to detect operations from another finger, then operation detection capability improves, but the device complexity increases
Solution Approach 1:
The sensors are locally integrated into the ring-shaped main body at specific positions to detect operations from another finger. This localized placement ensures accurate operation detection while minimizing the number of sensors needed, as each sensor is strategically positioned to capture the relevant finger movements without requiring a comprehensive array of sensors throughout the device

AI summary
There is provided an input device, a system, and a control method capable of performing an operation input that is more natural, less burdensome, and less bothersome in operations in daily life. The input device includes a ring-shaped main body portion to be mounted on a finger of a user; one or more sensors that are provided in the main body portion and that detect information regarding an operation input by another finger; a communication unit that performs wireless communication with an external device; and a control unit that performs control to transmit the information regarding the operation input detected by the one or more sensors to the external device by the communication unit.
