From Brain Signals to Adaptive Interfaces: Using fNIRS in HCI
نویسندگان
چکیده
Functional near-infrared spectroscopy (fNIRS) is an emerging noninvasive, lightweight imaging tool which can measure blood oxygenation levels in the brain. In this chapter, we describe the fNIRS device and its potential within the realm of human-computer interaction (HCI). We discuss research that explores the kinds of states that can be measured with fNIRS, and we describe initial research and prototypes that can use this objective, real time information about users’ states as input to adaptive user interfaces.

Passive brain-computer interfaces are designed to use brain activity as an additional input, allowing the adaptation of the interface in real time according to the user’s mental state. While most current brain computer interface research (BCI) is designed for direct use with disabled users, our research focuses on passive BCIs for healthy users. We employ functional near-infrared spectroscopy (...
