Around device interaction for controlling an electronic device, for controlling a computer game and for user verification

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a system enabling interaction with electronic devices, such as smartphones or tablets, using a magnetic sensor and a separate magnetic element (like a ring or stick). When the user moves the magnetic element in 3D space around the device, the built-in sensor detects the movement, allowing the device to interpret gestures for commands, game control, or even user authentication. This innovative method expands interaction beyond touch screens by leveraging widely available magnetic sensors, providing more intuitive and contactless control over devices.

Use CasesContent extracted from patent full text and abstract with AI.

• 3D gesture-based control of mobile devices, such as turning pages, zooming, or changing settings without touching the screen
• Advanced, immersive control schemes for mobile and computer games, including multiplayer scenarios with multiple magnetic elements
• Contactless user authentication using unique, gesture-based magnetic signatures instead of PIN codes, passwords, or biometrics
• Accessible device interaction for users with disabilities who have difficulty using touchscreens or physical buttons
• Executing commands on a device while it is not directly visible (e.g., when inside a pocket, purse, or bag)
• Launching specific applications or performing tasks by defined 3D gestures near the device
• Controlling wearable electronics, smartwatches, or headsets hands-free

BenefitsContent extracted from patent full text and abstract with AI.

• Enables intuitive, natural, and contactless interaction with electronic devices using simple gestures
• Allows for advanced 3D interactions and richer user experiences compared to current touch or orientation-based controls
• Reduces screen occlusion—users can interact without covering the display, enhancing visibility
• Cost-effective implementation as most modern devices already contain suitable magnetic sensors, requiring only a low-cost magnetic accessory
• Improved accessibility for disabled users or those in challenging environments
• Enhanced security for user verification via hard-to-forge gesture signatures
• Supports more sophisticated multi-user and multiplayer interactions through use of multiple magnetic elements
• Not affected by lighting or visual occlusion issues typical of camera- or infrared-based gesture systems

Patent Abstract

An electronic device (2) has an around device interaction means for interacting with a user of the electronic device (2). Therein the around device interaction means comprises a magnetic sensor for measuring a magnetic field strength and controlling means with which the electronic device (2) is controllable according to a movement of a magnetic element (3; 30) while the magnetic field strength of the magnetic element (3; 30) is measured by the magnetic sensor. According to the invention, the human-computer-interaction is based on the magnetic sensor or compass sensor, respectively, which is integrated in more and more standard electronic devices and in particular in mobile electronic devices. Thus, 3D human-computer-interaction can be implemented in a comparably simple and efficient manner.
