LiveSynergy – Bridging the Gap between Virtual and Physical Worlds

LiveSynergy is a novel magnetic-based wireless proximity detection platform, with accuracy and consistency better than existing solutions such as BLE, WiFi, ZigBee, and long-range RFID. Building on top of this platform, we provide cloud-based APIs that enable real-time and rich interactions between humans and their physical environment. LiveSynergy enables a range of indoor applications such as location-based targeted advertising and presence detection.

About LiveSynergy

LiveSynergy provides reliable proximity sensing and open interactive abstractions
for physical spaces and objects, to enable rich interactions between humans and their environment. The following is our hardware platform:

Pulse (left) and Link (right)

Pulse (left) consists of four primary hardware components: microcontroller (MCU) and radio, magnetic transmitter tuned at 125kHz, energy metering, and a mechanical relay for actuation.

Link (right) is a mobile device carried by humans to receive and decode the IDs from dynamic magnetic fields transmitted by Pulses.

Building on top of this magnetic-based wireless proximity detection platform, we provide cloud-based APIs that enable real-time and rich interactions between humans and their physical environment, as seen in the system architecture below.

End-to-end system architecture includes three main components: the hardware platform for detecting when humans enter and exit cafeteria counters; a networking and data representation layer enabling communication among counters, services in the cloud, and app clients; and an application layer consisting of a mobile application for providing feedback and visualization.

LiveSynergy enables a range of indoor applications such as location-based targeted advertising and presence detection. Take the location-based targeted advertising as an example, a Pulse, installed at the Teppanyaki counter is projecting a proximity zone of 5m radius. Links carried by diners in their pockets detect this zone as they enter.

 

When his Link detects the Pulse ID of the entrance and forward to the server, our web service sends a notification message to his mobile phone. The phone displays a notification at the top of the screen without interrupting the foreground application (Internet Explorer). Clicking the notification opens the main screen of our mobile application with the menu and promotional items. At the “Japanese counter”, the web service pushes counter-specific coupons (tuna sashimi). And more interesting location-based application can be built reliably on top of our platform.

             The diners receive the notification upon entering the cafe, which do not interrupt the current web browsing. After clicking the notification, today's menu is availabe from a RESTful server, so diners can have a more convenient way to order. Coupons or other location-based services can be delivered to diners when he move towards this counter.
