Settlement Terminal Orientation Detection for Secure Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing settlement terminal devices face challenges in secure and convenient input operations and display confirmations, especially when the orientation of the device changes with respect to gravity, leading to customer service deterioration and increased transaction times.
Innovation Solution
A settlement terminal device equipped with a first and second information processing unit, including orientation detection, which adjusts the display content orientation based on gravity, ensuring secure and easy input operations and display confirmations, regardless of the device's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the settlement terminal device is located at a place distant from the store clerk and the customer, then the transaction can be performed, but the time for which the store clerk keeps the customer's card increases and customer service deteriorates
Solution Approach 1:
The settlement terminal device is divided into multiple information processing units (first information processing unit and second information processing unit), each capable of independently processing settlement operations. This segmentation allows the customer to perform settlement operations at their own location without requiring the store clerk to hold the card for extended periods, thereby reducing card holding time while maintaining transaction processing capability.
2Productivity
If the settlement terminal device is located at a place distant from the store clerk and the customer, then the transaction can be performed, but the time required for the store clerk to complete settlement increases
Solution Approach 1:
The customer is enabled to perform settlement operations independently using the settlement terminal device at their own location. The customer can input their own signature and complete the settlement process without requiring the store clerk to be physically present or to manually complete the settlement, thereby significantly reducing the time required for settlement completion.
3Ease of operation
If the orientation of the settlement terminal device is not considered, then the device structure remains simple, but it becomes difficult to perform input operation or display confirming operation depending on the device orientation
Solution Approach 1:
The display unit dynamically adjusts the display content orientation based on the detected orientation of the settlement terminal device. The system rotates or reorients the displayed information according to how the device is held (portrait, landscape, or other orientations), ensuring that input and display operations remain intuitive and easy regardless of device orientation, while adding only minimal complexity through orientation detection capabilities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables seamless and secure input operations and display confirmations, improving user convenience and reducing transaction times by dynamically adjusting the display content orientation in response to changes in the device's orientation relative to gravity.

AI summary
Provided is a settlement terminal device including a plurality of information processing units. The settlement terminal device includes a first information processing unit, a secure second information processing unit, and an orientation detection unit which detects a direction of the settlement terminal device with respect to gravity. The first information processing unit reflects a detection result of the orientation detection unit on an orientation of a first display content displayed on the first display unit, and the second information processing unit determines whether or not to reflect the detection result of the orientation detection unit on an orientation of a second display content, in accordance with the second display content displayed on the second display unit. Thereby, a settlement terminal device capable of easily performing an input operation and display confirmation in a settlement process is provided.
