We propose a novel search technique called IteMinder that helps users find property in a room using passive RFID and an autonomous robot. First, we attach RFID tags to the target items and at typical locations in a room. We also attach an RFID reader and a laser rangefinder to the robot. The robot can move around the entire room automatically while avoiding(More)
In this research, we addressed the problem of visualizing route histories on a mobile device. We developed a solution, which combines the visualization of three route history parameters: speed, direction, and location. The visualization was tested in a laboratory evaluation with 12 subjects. The results showed that by using the visualization the subjects(More)
Geographic information system (GIS) is traditionally used with desktop computers. The development of embedded, wireless, and positioning technologies have opened possibilities to apply GIS in new application areas and conditions. In this research area interoperability issues have been regognized to be one of the main challenges of in situ measurements in(More)
In this demonstration paper we will present our test application which has been designed for using geosensor network (GSN) nodes with low-rate communication. Our demonstration will show how GSN nodes can be used in low-rate networks based standardized binary encoding communication. The designed geosensor application has been created over the Locawe platform(More)
