and behaviours as people experience them
● …[long term] to explore whether machine learning
approaches could infer people's subjective
responses/complex behaviours
● …[vision] to understand the extent that behavioural
support can be automated and personalised with
sensor data

How should we design the
relationship between interacting
and collecting 'labelled' data?
12. We built a system that
includes: sensor data
collection, ESM
interfaces, etc., and
remote reconfiguration.
13. 22 users; 1-month;
questions about mood
& current context
(location, sociability);
background sensing
from many sensors;
triggers remotely
reconfigured weekly.

15. Dissonance; a tension or clash resulting
from the combination of two
disharmonious elements
16. Dissonance; between using sensor
states to trigger ESM surveys while
using sensor data to quantify context
and behaviour.
