Human-computer Trust

Theoretical underpinnings

HCI perspective• Study computing and computational artifacts as they

relate to the human condition.

Trust perspective• Study how it can be crucial element in human

relationship

Human Computer Trust• Represents the Value centered Interactions

Participation

Cooperation

The interception of Human-Computer interactions components; and The dynamic nature of trust in relationships

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 • more about the… activities.

Information technology context is• becoming pervasive; and

Computing is• becoming ubiquitous

WHY TRUST….

Contextual aim

Trust contemplates• Social phenomena• A complex two-way relationship

Trust emerges from• An interpersonal organization• A specific social situation• A specific social context

• Positive experiences• Interactions• Active participation • Cooperative relations

SUPPORT&

SUSTAIN

Contextual aim

Trusting represents• A reinsurance element

Trusting comes associated • With certain properties that help to support

users intended behaviours

Trusting relies on• The identification of trustworthy making

qualities

What underlies people's beliefs

The research…

The research contemplates

A need for identify 1. trust social values (qualities) that underlies

people’s trust beliefs

2. The reliability of those trustworthy making qualities

3. How those (trustworthy making qualities) are represented in today’s ongoing cultural shift

Stage 1 (the process)

Stage 2 (Validation)

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 commitment of

both parts

Strong incentives to believe that

determinate person, service or tool is in

fact trustworthy

Predominant factorsAttitudes towards sharing• Shared history & identity• Respect and have honorable intentions• Be reliable• Be known• Sympathy & friendliness

Attitudes towards relate• Honesty & transparency• know the person • Be willing to• Empathy• Reliable source

Attitudes towards communicate• Honest & Transparent behaviours• Receive support• Feel secure• Share similar interests

Trust & Privacyby safe we mean…felling a degree of control who will read or have access to their shared resources, comments and assignments.

Students feel safe to share

Trust & collaboration

Is much related with commitments • But those are perceived differently from person to

person

Trust influence commitments• group working dynamic

Major needs ->• Predict how if others will behave as expected

Trust-enabling interactions

By observing trust enabling qualities we can• 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

Human Computer Trust model

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.
