Objective The aim of this study is to investigate whether visual aids can enhance decision outcomes for multi-attribute choice making problems with practical datasets. Background: Information visualization techniques have been used to develop visual aids to help consumers process the given information, thus improving decision outcomes by increasing decision quality. However, due to the fact that decision quality is difficult to measure, several studies used context-free data to minimize the impact of participants’ preference structures to reduce subjective factors. To better understand whether these visual aids are effective in a more practical setting, we need to conduct studies using data with context.
Method: The experiment was conducted as a between-subject study with two interfaces, SimulSort for the interactive visualization interface and Typical Sorting for the non-visual traditional interface. Each participant had three decision making trials and the decision-making quality was measured by selecting the nondominated option that is considered as the best choice. A total of 127 participants participated through an online experiment platform.
Results: Using the SimulSort interface, the odds of selecting a nondominated option, compared to not selecting it, increased and has a significant effect. Both the interface and type of selected option had significant main effects on the time spent. A posthoc analysis revealed that the type of selected option had significant effect for the participants who used SimulSort by spending more time to make a decision, however, this effect was not present for the participants who used Typical Sorting. The participants were generally confident on their decisions while using both interfaces.
Conclusion: The results revealed that SimulSort could enhance the probability of making a better decision than compared to Typical Sorting. The study also shows an effective way to conduct a controlled study that has an objective measure for decision making using data with context.
Application: The results of the experiment can help implement visual aids to help consumers make better decisions in everyday life.
