Context-Aware Services

Ubiquitous and pervasive computing envisions context-aware systems that gather real world information from many fixed and mobile microchips and sensors integrated in everyday objects. To provide valuable services, it is necessary to estimate the location of users or objects

Locating assets and users is one of the key issues to enable transparent and immediate services. Several interesting location-aware applications are emerging in everyday life: Indoor asset tracking and monitoring of objects; People tracking inside a facility; Shopping assistance in malls; Museum guide systems;

Features

Low Cost

WALK does not rely on custom hardware. It exploits available networks and devices, such as Wi-Fi 802.11 abg/ac/n, Bluetooth

Fast Deployment

WALK follows the plug and play paradigm. Just few information about the building and its wireless devices are required to get started

No Maintenance

WALK does not rely on Wireless fingerprints neither on long offline training. You won't have to update the system periodically

Scalable Accuracy

Position accuracy is estimated in real-time, it depends on the environment complexity and available hardware, up to few meters

Innovative

It exploits state-of-the-art and innovative research algorithms

Extendible

WALK supports environmental changes and network upgrades nicely. It comes with interactive GUI tools to assists the configuration process

Technology

Wireless Localization

In the demonstration, only wireless information are used as they are available from the standard smart-phone. No interpolations, filters or dead-reckoning sensors

Using the Path-Loss propagation wireless model, WaLK requires only the knowledge of Wi-Fi Access Points displacement

When blueprint and environment information are available, WaLK can exploit complex wireless simulation modeling and improve accuracy

Occupancy Estimation

In the demonstration, only wireless information are used as they are available from the standard smart-phone. No interpolations, filters or dead-reckoning sensors

Room occupancy statistics and alerts are very useful for emergency and queue management
