how can sensor data be used toinfer how people feel?
@neal_lathiauniversity of cambridge
how many smartphones do you have?
how often do you carry your phone with you (%) ?
how often do you carry your phone with you (%) ?
research: 90% of the time it is in the same room as you
making it a powerful, personal device that can sense, monitor, and interact with you
sense (infer): activities, social interactions, mobility, ambient sound
in the moment
monitor: green transportation habits and modes, fitness levels
individuals over time
interact: social network broadcasts, ubiquitous technology evaluation, persuasive interfaces
understand & persuade
now: a tool for psychology research“ubiquitous, intimate, sensor-rich, computationally
powerful, remotely accessible”
