Designing HCI Experiments
Learning how to design and conduct an experiment with human participants is a skill required of all researchers in human-computer interaction. In this chapter I describe the core details of designing and conducting HCI experiments.
One way to think about experiment design is through a signal and noise metaphor. In the metaphor, we divide our observations and measurements into two components: signal and noise. (See Figure 5.1.) The source shows a time series. A slight upward trend is apparent; however, the variability or noise in the source makes this difficult to detect. If we separate the source into components for signal and noise, the trend in the signal is clear.
Figure 5.1 Signal-to-noise conceptualization ...
