Presence Detection Terminal Contactless Interaction via Intent Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing presence detection terminals require direct interaction, leading to user-unfriendly operations and a high risk of incorrect bookings, as individuals must approach the terminal to log in or out, often using a personal access medium and risking unintentional or intentional errors.
Innovation Solution
A presence detection terminal equipped with a control unit, memory management unit, sensor unit, identification engine, interaction detection engine, and wakeup engine, allowing for contactless interaction by detecting presence and intentions through sensors and processing data to automate the booking process, reducing the need for direct interaction and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If direct interaction is required at the terminal, then identification accuracy is improved, but ease of operation deteriorates and risk of incorrect entries increases
Solution Approach 1:
The patent replaces the mechanical system of direct physical interaction (holding access medium against terminal, standing at terminal) with an optical/acoustic field-based detection system. Sensors detect presence and intent information through electromagnetic fields and acoustic waves, allowing identification without mechanical contact. This substitution maintains identification accuracy while dramatically improving ease of operation by enabling contactless interaction from a distance.
Solution Approach 2:
The patent introduces sensor units as intermediaries between the person and the terminal processing unit. These sensors act as mediators that detect presence and intent information from a distance and transmit it to the terminal for processing. This intermediary system enables accurate identification without requiring direct physical interaction, resolving the contradiction between measurement precision and ease of operation.
2Device complexity
If direct interaction at terminal is required, then device complexity is reduced, but risk of incorrect bookings increases
Solution Approach 1:
The patent implements preliminary detection of presence and intent information before the actual identification and booking process. The sensor units detect whether a person intends to interact with the terminal before triggering the identification sequence. This preliminary action prevents unintended or accidental bookings by ensuring the person genuinely intends to clock in or out, thereby improving reliability without significantly increasing device complexity.
Solution Approach 2:
The system incorporates feedback mechanisms where the terminal provides information about detected presence and intent, and the person can confirm or cancel the intended action before final booking. This feedback loop prevents incorrect bookings by allowing verification of the intended action, improving reliability while maintaining relatively simple device architecture.
3Ease of operation
If contactless interaction is enabled, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functional sensor units that can detect multiple types of information (presence, intent, identification data) using a single integrated sensing system. Rather than requiring separate devices for each function, the universal sensor unit performs multiple detection tasks, enabling contactless interaction while minimizing the increase in device complexity through functional integration.
