Abstract
In Human Factors research, measuring the construct of workload is common. This often takes the form of using subjective questionnaires such as the NASA-TLX. Another approach analyses operators' performance in a secondary task to quantify and measure workload. We developed and, thus, propose one such task: the (Tactile) Signal Detection Task (TSDT). In two experimental studies, the performance of the TSDT was compared to NASA-TLX ratings during varying workload conditions in a laboratory setting. Study 2 additionally investigated the susceptibility of the NASA-TLX and the TSDT to different difficulty primes. Results indicate a good performance of the TSDT in measuring workload, a susceptibility of the NASA-TLX, and a non-susceptibility of the TSDT to difficulty primes. Further results and practical implications are discussed.
