IrRC-Logger: Empirical analysis of users behavior on remote controller log

In this paper, we experimented for analyzing users´ behavior on remote controller logs. We recorded the DVD recorder´s signal data using IrRC-logger can record infrared signal (Ir-signal) from remote controller to the appliances. We focused on interval time between error/correct signal and previous signal, and analyzed a difference between error interval time and correct interval time. The results of t-test show that the mean of interval time data for the error cases is statistically different from that for the correct cases. There is a possibility that error operations are discovered by focusing long interval time from long recoded logs.
