Abstract
A method for acknowledging presence in a context-aware environment includes the steps of detecting, with at least one context awareness mechanism, if a context-aware device is within a predetermined range or distance. The method further includes, that when the vehicle device or personal device is within a range of the moving vehicle, sending a request of acknowledgment to the vehicle device or personal device. In events where the moving vehicle device does not receive an acknowledgment from another vehicle or a worker within a predetermined duration, the moving vehicle is automatically stopped. In events where the moving vehicle device receives an acknowledgment from all the devices within the predetermined range, the device of the moving vehicle considers the context as non-hazardous and the vehicle may continue along its path.
