Problem
As the complexity and variety of gestures in user interfaces increase, users face challenges in correctly remembering and inputting gestures, leading to decreased convenience and potential irritability due to incorrect recognition.
Innovation Solution
A gesture input device and method that includes an input unit for image and voice information, a detection unit, a prediction unit to predict desired gestures based on detection results, and a notification unit to inform users of the actions needed to input these gestures, enhancing correct input even with increased complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the kind and complexity of gestures are increased to improve interface functionality, then the versatility of the user interface is improved, but the ease of operation deteriorates as users find it harder to remember and correctly input gestures
Solution Approach 1:
The system performs preliminary recognition of the user's current gesture and proactively notifies the user of the expected next gesture before the user actually performs it. This advance notification helps users remember and correctly execute complex gestures by providing guidance in advance, thereby maintaining ease of operation even as gesture complexity increases.
Solution Approach 2:
The system provides continuous feedback to the user by notifying them of the gesture that is expected next based on their current gesture input. This feedback mechanism guides users through complex gesture sequences, reducing the cognitive load of remembering multiple gestures and improving ease of operation while maintaining high versatility.
2Adaptability or versatility
If the kind and complexity of gestures are increased to provide more functionality, then the adaptability of the interface is improved, but the reliability of gesture recognition deteriorates as users may feel anxious about whether gestures are correctly recognized
Solution Approach 1:
The system enhances reliability by providing feedback that notifies users of the expected next gesture based on their current input. This creates a verification mechanism where users can confirm their gesture sequence is being correctly recognized, reducing anxiety and improving perceived reliability even as gesture complexity increases.
Solution Approach 2:
By notifying users of the expected next gesture in advance, the system allows users to verify their input sequence before completing it. This preliminary notification acts as a confirmation mechanism that enhances reliability, ensuring users their gestures are being correctly interpreted throughout the sequence.
3Adaptability or versatility
If more gestures are required to provide comprehensive functionality, then the versatility is improved, but the loss of information increases as users may forget gesture sequences
Solution Approach 1:
The system continuously provides feedback about the expected next gesture, effectively offloading the memory burden from the user to the system. Users no longer need to remember entire complex gesture sequences, as the system reminds them of the next required gesture, thereby reducing information loss while maintaining comprehensive functionality.
Solution Approach 2:
The system serves itself by automatically tracking the gesture sequence and notifying users of what comes next, eliminating the need for users to mentally track and remember the entire gesture protocol. This self-service approach to gesture guidance reduces the cognitive burden on users while maintaining versatile functionality.

AI summary
A gesture input device includes an input unit to which image information representing an action is input. The gesture input device also includes a detection unit that detects the action based on a shape of the input image information. The gesture input device further includes a prediction unit that predicts one or more gestures based on a detection result of the action. In addition, the gesture input device includes a notification unit that notifies an action to be performed next to input the predicted one or more gestures.
