Abstract
An exemplary method of determining location information includes sensing a temperature of an object or person in a sensing field of at least one temperature sensor at each of a plurality of measurement periods. A relationship between the sensed temperature at a first one of the measurement periods and the sensed temperature at a second, later one of the measurement periods is determined. A determination is made from the determined relationship whether the object or person moved relative to the temperature sensor during a time from the first one of the measurement periods to the second one of the measurement periods.
