In the current paper we present a field comparison of techniques for selecting one's current location in mobile locationbased systems. Four location selection techniques are described, which are physical selection using RFID technology, automatic selection based on GPS coordinates, selection from a mobile map with a stylus, and a textual selection technique involving a virtual keyboard and a selection list. These techniques were compared in a field experiment with 12 test users. The results showed that all four implemented techniques were evaluated as highly usable. Physical selection with RFID and selection from a mobile map with a stylus were the preferred location selection techniques by the test users. KEYWORDS Context-awareness, location-based systems, mobile maps, selection methods, RFID, GPS.
