Home Communication System with Face Recognition and Automatic Resident Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home communication systems with multiple residents require visitors to manually scroll through numerous bell buttons to find the correct resident, making it cumbersome and inefficient.
Innovation Solution
A home communication system that uses face recognition and image processing to adapt the display, linking image information with stored scrolling information, allowing the system to automatically select and display the correct resident, and enabling automatic communication and control of building systems based on recognized visitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If manual scrolling through bell buttons is used to select a resident, then the system supports a large number of residents, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical interaction of manually scrolling through bell buttons with an optical recognition system. A camera captures the visitor's face, and an image comparison device automatically identifies the visitor by comparing captured images with stored reference images, thereby substituting manual mechanical selection with automated optical recognition.
Solution Approach 2:
The system performs self-service by automatically identifying the visitor and presenting relevant information without requiring manual intervention. The image comparison device and control unit work autonomously to recognize the visitor and display appropriate resident information, eliminating the need for the visitor to manually scroll through options.
2Loss of information
If all resident names are displayed simultaneously, then complete information is available, but the display becomes cluttered and difficult to navigate
Solution Approach 1:
The system performs preliminary action by pre-storing reference images of all residents in the reference memory during system setup. This allows the image comparison device to quickly retrieve and compare against stored images without requiring real-time display of all resident names, thus maintaining information availability while simplifying the display interface.
Solution Approach 2:
The patent segments the information display by showing only relevant resident information based on visitor recognition. Instead of displaying all resident names simultaneously, the system divides the display into relevant and irrelevant sections, showing only the information pertinent to the identified visitor, thereby reducing clutter while maintaining accessibility to complete information through the recognition system.

AI summary
A home communication system (1) is proposed, comprising at least one door station (2), at least one door opener (21), and a plurality of apartment stations (12, 18, 19), • wherein the door station (1) includes a camera (3) with image processing for capturing visitors (A), a reference memory (7) for stored image information (IA) of visitors (A), an evaluation/processing/control unit (9) connected to the camera (3) and reference memory (7), including an image comparison device (8), and a scroll display (4) with a scrollable, graphical user interface, with which a specific resident can be selected from a list (6) of all residents (B), • wherein the links between specific image information (IA) and specific apartment stations (12, 18, 19) are stored in the reference memory (4).• wherein the evaluation/processing/control unit (9) performs a coincidence evaluation between an image currently captured by the camera (3) and the image information (IA) of the reference memory (7), • wherein the scroll display (4) can be controlled with a scroll information (IB) linked to and stored with the image information (IA) when a sufficient match is detected between a specific piece of image information (IA) and the image currently captured by the camera (3), in order to selectively display a specific resident (B).
