A student who is blind can take lab measurements.
Researchers have created a workstation that allows a student who is blind to independently take lab measurements with a probe, electronic balance, and digital multimeter. This workstation was developed by a group at East Carolina University. It consists of an IBM-compatible PC, the Team Labs Personal Science Laboratory (PSL), and a Creative Labs Soundblaster Card which allows for sound output. Students are able to measure mass, temperature, pH, light intensity, AC and DC voltages and currents, resistance, frequency, and capacitance.
