Novel Interfaces & Interactions Research

Brain-computer interfaces are one of the hot topics in novel interaction design. We test an EEG (EPOC) device to identify whether we can effectively and efficiently use it as a monitoring and controlling tool. Brain waves can be one of the many signals to provide information about users' states (e.g., arousal, fatigue, workload, or emotions). Moreover, we can have people (those with disabilities or their hands occupied) control interfaces using an EEG device. We also have a plan to use it as a composing tool. In the iISoP platform, we will improvise harmonized music based on our body (based on movement tracking data) and mind (based on brainwave data). In addition, we investigate users' cognitive and affective states using fNIRS (functional Near-infrared spectroscopy), EEG, ECG, and EMG when they conduct a novel task (e.g., novel interfaces), an emotional task (e.g., seeing or hearing emotional stimuli), or dual tasks. Based on these experiments, we would also identify the relationship between cognitive processes and affective processes.

Based on well-formulated methodologies in psychology and human factors and professional design experience of automotive user interfaces, we further explore the next generation in-vehicle interfaces and services in terms of driving performance, safety, and user (driver and passengers) experiences. For example, we investigate the possibility of the use of subliminal cues (e.g., faint light, soft sounds, scent, tactile feedback, etc.) for drivers. To more actively explore the next generation in-vehicle interfaces, we have hosted a series of workshops (e.g., AutomotiveUI, UBICOMP, ICAD, Persuasive Tech, etc.) and edited journal special issues (e.g., Pervasive and Mobile Computing and MIT Presence: Teleoperators and Virtual Environments). This project is supported by Michigan Tech Transportation Institute Initiative Funding.
