1. Human-computer Trust

2. Theoretical underpinnings
HCI perspective
• Study computing and computational artifacts as they
relate to the human condition.
Participation
Cooperation
Trust perspective
• Study how it can be crucial element in human
relationship
Human Computer Trust
• Represents the Value centered Interactions
The interception of Human-Computer interactions
components; and The dynamic nature of trust in
relationships

3. key principles
The ongoing cultural shift
• a ever-widening range of digital artifacts is
transforming our daily lives.
The way we
communicate,
locate, play, learn,
and much more
How we relate to technology is
• less and less about the… devices; and

are represented in today’s ongoing cultural
shift

11. Results (associated notions)
Trusting is…
• process of believing in others behaviours
Reflects a
• risk
While some are more
willing to take the
risks others don’t
Level of

Major needs ->

• Enables more honest & transparent behaviours
• Predict others activities patterns
• Perceive others competencies
• creates emphatic relations which, enable Social
engagement,
• Diminish group hostility which, increase group
commitment
• Foster group motivation & willingness to cooperate

17. Application
Support the design of a instrument to Assess/
evaluate trust-enabling interaction design
qualities
Sousa, S., Lamas, D.;
Shmorgun, I.; Arakelyan, A.
(2014).
A design space for trust
enabling interaction design.
In MIDI 2014, ACM (2014)
This toolset provides
designers lenses to
assess the act of
design for trust-enable
interactions and further
evaluate if their design
propositions have
been reflected in the
design outcome.
