From Brain Signals to Adaptive Interfaces: Using fNIRS in HCI

Abstract

Functional near-infrared spectroscopy (fNIRS) is an emerging non-invasive, 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.
