Abstract
Prior to this project, a hypothesis is made that the accuracy of an Indoor Positioning System (IPS) with LANDMARC approach, can be traded-off based on the usage behaviour. To study the validation of the statement, this project has implemented the IPS and a series of tests. The tests first define the parameters: Tradeoff, Usage Behaviour, and Accuracy. Tradeoff is defined as task success; while Usage Behaviour is defined as case study settings; for Accuracy is defined in Eq. 3.1. The tests manipulate Usage Behaviour to observe the Tradeoff and Accuracy. The way is using three maps of different landmark separations and two different task requirements: “Correct landmark as task success” and “Correct position within allowable trials as task success”. Consequently, the IPS software has found faulty during carrying out the accuracy tradeoff study. Thus, a proper investigation to the study cannot be completed. But based on the obtained results, the high accuracy happened by chance in a faulty IPS does not necessary help in making task success, for which the usage behaviour requires accurate position. Future study of the test is required.
