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.
