In the recent March issue, a project was outlined for creating a smartwatch-like Human Interface Device (HID) featuring a keyboard and touchpad. To enhance its functionality, location tracking capabilities can be integrated without relying on traditional GPS systems. This is particularly advantageous in environments where GPS signals are limited, such as indoors or in obstructed areas.
A groundbreaking method for location tracking involves utilizing Wi-Fi SSID signals, magnetic compass data, and the Indusboard – a compact IoT device equipped with Wi-Fi capabilities and a magnetic compass sensor. By harnessing Wi-Fi signals and compass data, real-time location tracking becomes feasible even in challenging environments where GPS signals may falter.
The SSID, which stands for Service Set Identifier, serves as a critical identifier for wireless networks, assigned to a Wi-Fi network during its setup process.
This SSID-based location tracking system holds immense potential across various scenarios, including:
- Indoor Navigation: Facilitating navigation within buildings where GPS signals struggle to penetrate or are altogether unavailable.
- Asset Tracking: Streamlining asset tracking operations within warehouses or manufacturing facilities where GPS signals may be unreliable.
- Personnel Monitoring: Enabling efficient monitoring and tracking of personnel movement in expansive venues or during events where traditional GPS signals may be inadequate.
- Location-Based Marketing: Enhancing the effectiveness of location-based advertising and marketing campaigns by accurately tracking user positions based on Wi-Fi SSID signals.
Integrating this novel approach to location tracking expands the utility of the smartwatch-like HID project, offering versatility and effectiveness in diverse settings where traditional GPS-based systems may fall short.
