Elevator Call Automation via Gesture and Beacon Intent Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for calling an elevator using a mobile device often result in unnecessary calls due to the detection of beacon signals, leading to user annoyance and inefficiency, as users must manually activate an application to initiate a call, which can be time-consuming and intrusive.
Innovation Solution
A method that recognizes user intent through gestures and beacon signal analysis, using sensors like acceleration, gyroscope, and brightness sensors to display a user interface for elevator calls only when the user intends to use the system, thereby reducing unnecessary notifications and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a beacon signal is detected by a user's mobile communication device to determine the user's distance from the elevator, then the elevator call can be automatically executed, but this can lead to unnecessary elevator calls and user annoyance
Solution Approach 1:
The patent combines multiple detection methods (beacon signal detection, gesture recognition, application state detection) into a unified user intent detection system. The elevator call is only triggered when all conditions are met: beacon signal is detected, user performs a specific gesture (such as double-clicking), and the elevator application is active. This merging of multiple criteria resolves the contradiction by maintaining automation while significantly improving the reliability of user intent detection, thereby eliminating unnecessary calls.
Solution Approach 2:
The system implements feedback by continuously monitoring user actions and system state. When a beacon signal is detected, the system waits for additional user confirmation through gesture recognition and application state verification before executing the elevator call. This feedback mechanism ensures that automatic calls are only made when the user truly intends to use the elevator, resolving the contradiction between automation and reliability.
2Ease of operation
If the user must find and activate the corresponding application on their device to use the elevator system, then the system can provide user guidance, but this can be time-consuming
Solution Approach 1:
The patent applies preliminary action by requiring the user to perform a gesture (such as double-clicking) and have the application already active before the elevator call is executed. This preliminary preparation of the system state (application already running, gesture already performed) eliminates the time-consuming step of searching for and activating the application at the moment of needing the elevator, thereby resolving the contradiction between ease of operation and time loss.
3Loss of information
If mobile phones detect Bluetooth signals from beacons and communicate this to the user, then the user can be informed about nearby services, but this can lead to numerous annoying notifications for the user
Solution Approach 1:
The patent extracts the essential function (elevator call initiation) from the general beacon notification system. Instead of notifying the user about every beacon detected, the system only triggers an elevator call when all specific conditions are met: the correct beacon is detected, the user performs the designated gesture, and the elevator application is active. This extraction resolves the contradiction by eliminating unnecessary notifications while preserving the useful information about nearby elevator services.
