Abstract
Flow is an affective state of optimal experience,
total immersion and high productivity. While often
associated with (professional) sports, it is a
valuable information in several scenarios ranging
from work environments to user experience evaluations,
and we expect it to be a potential reward
signal for human-in-the-loop reinforcement learning
systems. Traditionally, flow has been assessed
through questionnaires which prevents its use in
online, real-time environments. In this work, we
present our findings towards estimating a user’s
flow state based on physiological signals measured
using wearable devices. We conducted a study with
participants playing the game Tetris in varying difficulty
levels, leading to boredom, stress, and flow.
Using an end-to-end deep learning architecture, we
achieve an accuracy of 67.50% in recognizing high
flow vs. low flow states and 49.23% in distinguishing
all three affective states boredom, flow, and
stress.
