Gesture-Controlled Intercom via Proximity Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack the ability to control intercom units without physical contact, especially in scenarios where the user's hands are occupied or dirty, such as while cooking, and cannot efficiently handle notifications from intercom units in different rooms.
Innovation Solution
An electronic device equipped with a proximity sensor and a communication interface that allows gesture-based control of intercom units, enabling users to manage call notifications and interact with both indoor and outdoor intercom units without physical contact by detecting and processing gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture detection is added to enable hands-free operation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent combines the proximity sensor's gesture detection capability with the existing intercom control functions. The control unit integrates both gesture recognition and intercom control logic into a single system, allowing the electronic device to perform multiple functions (gesture control and intercom operation) without requiring separate devices or systems.
Solution Approach 2:
The proximity sensor is designed to serve dual purposes: detecting proximity events and detecting gestures for controlling the intercom. This multi-functionality allows the same hardware component to provide both proximity-based triggers and gesture-based commands, reducing the need for additional specialized sensors while enhancing operational flexibility.
2Object-affected harmful factors
If gesture-based control is implemented, then cleanliness is improved (hands-free operation), but measurement precision requirements increase
Solution Approach 1:
The system uses proximity detection as a preliminary trigger before requiring gesture recognition. When a proximity event is detected, the system activates gesture-based control modes, allowing users to perform gestures in close proximity to the device. This two-stage approach reduces the precision requirements compared to full gesture recognition from a distance, while still maintaining hands-free operation for cleanliness.

AI summary
An electronic device includes a proximity sensor, a communication interface that communicates with an indoor unit of an intercom, and a controller. When the communication interface acquires a signal indicating receipt of a call notification by the indoor unit of the intercom, the controller executes processing to control the indoor unit of the intercom based on a gesture detected by the proximity sensor. An electronic device includes a proximity sensor, a communication interface that communicates with an outdoor unit of an intercom, and a controller. When the communication interface acquires a call notification from the outdoor unit of the intercom, the controller executes processing to control the outdoor unit of the intercom based on a gesture detected by the proximity sensor.
