An indoor guidance system for the blind using fluorescent lights--relationship between receiving signal and walking speed.

The aim of this study is to demonstrate the relationship between the user's walking speed and the data transmission speed in an indoor guidance system using fluorescent lights and a wireless LAN. A simulation formula is used to give out the direct relationship between the parameters. We simulated four angles (30 degrees-90 degrees) between the sensor and the horizontal direction. Three different walking speeds and four different data transmission speeds (1200 bps-9600 bps) were applied at all angles. Also we designed a series of experiments to validate the formula.
