| Abstract: | Physicalization of data is an emerging topic and an area of research that has a lot of potential. The ability to give data a physical shape has practical significance for explaining complex systems and making data accessible. In this research, a standard Brain-Computer Interface (BCI) experiment will be conducted to collect brain data while interacting with data physicalization. This is a within-subject design study that exposes the participant to multiple conditions by performing data exploration tasks. Furthermore, the brain signal of each participant was recorded through an EEG recording kit, and the results were pre-processed to remove noise, and the data was partitioned into four segments that isolate the different experiment conditions for a later comparison. Afterward, data was analyzed to show the brain activity of different frequency bands, and this is done by graph visualizations that plot the voltage potential difference of multiple electrode locations against time. These findings show that the alpha band is mostly active during the resting state. In contrast, during the other conditions, the interaction with the physicalization of the data provoked high levels of beta and gamma waves. |
