|Abstract:||A brain-computer interface (BCI) infers our actions, intentions and psychological states (e.g. emotion, attention) solely by interpreting our brain signals. It uses the inferences it makes to manipulate a computer. Although BCIs have long been used exclusively to support disabled people (e.g. through brain-controlled wheelchairs, spellers), with the emerging low-cost and portable hardware, they have started to be considered for a variety of human-computer interaction applications for non-disabled people as well. Among these, games have been receiving the interest of researchers and practitioners.
In BCI research, games have been used solely to demonstrate the performance of signal processing and analysis methods. Therefore, they have been evaluated only for their performance (e.g. recognition accuracy, information transfer rate). However, games are not meant to satisfy our practical needs. They satisfy our hedonic needs. They challenge us, let us make our fantasies true, evoke our memories, and so on. We look for these experiences while playing games. Thus, rather than the performance of the controller used, the user experience of the game is essential.
In my work, I investigated how the BCI control can influence the user experience of a computer game. My work consisted of three studies in each of which I evaluated different user experience related concepts and used different data collection methods. In all the studies, participants played an experimental multimodal game that we had developed, called ‘Mind the Sheep!’. They controlled 3 dogs to herd 10 sheep across a meadow. Their goal was to pen all the sheep as quickly as possible.
My work shows that the challenge, cognitive involvement and novelty offered by BCI can improve emotional social interaction, enhance the sense of immersion and satisfy hedonic human needs. Based on the findings of my studies, in my work, I provide guidelines for building enjoyable BCI games.
