AR Keypad Overlay for Secure Keyless Door Code Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door unlocking methods, such as using keys or physical keypads, pose security risks and require physical modifications, increasing costs and complexity, while physical keypads can be visually unappealing and vulnerable to code guessing.
Innovation Solution
An augmented reality (AR) displayed keypad system that superimposes a virtual keypad on a user's device image, allowing users to input codes on the vehicle's exterior without actual markings, using camera tracking to verify inputs, ensuring security and eliminating the need for physical modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical keypad is installed on the vehicle exterior, then users can input access codes, but the vehicle's aesthetic appeal is compromised and security vulnerabilities increase
Solution Approach 1:
The patent creates a virtual copy of a physical keypad using augmented reality technology. The AR keypad is projected onto the vehicle exterior through a mobile device camera, allowing users to input codes without a physical keypad being installed. This copying approach maintains aesthetic appeal while providing code input functionality.
Solution Approach 2:
The patent replaces the mechanical physical keypad system with an optical/digital AR-based input system. Instead of physical buttons and switches, the system uses camera imaging, virtual overlay graphics, and touch screen interaction to achieve code input, eliminating the need for mechanical components on the vehicle exterior.
2Ease of operation
If a physical keypad is installed on the vehicle exterior, then users can input access codes, but security risks increase due to vulnerability to code guessing
Solution Approach 1:
By using a virtual AR keypad instead of a physical one, the system eliminates the security vulnerability of having a permanent, visible input interface on the vehicle. The virtual keypad exists only when activated through the mobile application, reducing opportunities for unauthorized code guessing.
Solution Approach 2:
The AR keypad implementation allows for dynamic changes in the code input process. The system can validate code entry in real-time, provide feedback during input, and potentially change the required code sequence or length based on security protocols, making unauthorized access more difficult compared to static physical keypads.
3Ease of operation
If a physical keypad is installed on the vehicle exterior, then code input is enabled, but costs and installation complexity increase
Solution Approach 1:
The virtual AR keypad eliminates the need for physical installation of keypad hardware, wiring, and mounting structures. The functionality is copied into the mobile device's software environment, requiring only the vehicle's existing camera and display systems, thereby reducing installation complexity and costs.
Solution Approach 2:
The mobile device serves multiple functions: it acts as the camera to capture the vehicle exterior, the display to show the AR keypad interface, the input device through its touch screen, and the processing unit to handle code validation. This multi-functionality eliminates the need for dedicated physical keypad hardware.
4Ease of operation
If a physical keypad is installed on the vehicle exterior, then code input is enabled, but manufacturing and installation costs increase
Solution Approach 1:
The virtual AR keypad is created through software rendering rather than physical manufacturing. The keypad interface is generated digitally and projected onto the vehicle exterior through the mobile device's display, eliminating all manufacturing costs associated with physical keypad components, materials, and assembly.
Solution Approach 2:
The patent substitutes mechanical manufacturing processes with digital software development. Instead of manufacturing physical buttons, housings, and mounting structures, the system uses software code to create the virtual keypad interface, significantly reducing manufacturing costs and complexity.

AI summary
In some implementations, a device may receive an indication of a code associated with granting authenticated access to a door. The device may transmit, to a user device, presentation information to cause an augmented reality image of an input pad to be displayed by the user device, wherein the augmented reality image is displayed over an area of an image of an exterior of the door via a user interface. The device may detect, via a camera device, one or more user inputs to the area of the exterior of the vehicle based on tracking a movement of a user. The device may identify an input code based on the one or more user inputs. The device may perform an action to cause the door to be unlocked based on the input code matching the code.
