Usable Trust in the IoT
•What is it?➥Trust as a decision‐basis for end‐users
➥“informed decisions”
➥Trust feedback mechanisms which are accepted by end‐users
•How to achieve?➥User‐centric design process
➥Personas
➥Requirements engineering

Personas
1212Personas ‐What are Personas?
1313Personas ‐What are Personas?
“...a hypothetical archetype of real users described in great detail and defined by their goals and needs, rather than just demographics.”
Lindgren et al. (2007)
“...a hypothetical archetype of real users described in great detail and defined by their goals and needs, rather than just demographics.”
Lindgren et al. (2007)
1414Personas ‐Why Personas?
•Rise developers‘ empathy for end‐users➥Know for whom artefacts are developed
•Consolidate the individual pictures from an abstract „the user“ to one concrete set of personas
➥Prevents “bending” of user definitions & projections
•Nearly none‐intrusive method➥Development‐style agnostic

Requirements for Usable Trust
•3‐folded requirements➥Technical requirements
➥Requirements for VR
➥User‐requirements
➥Method: focus groups + usability heuristics + questionnaires(questionnaires related to the scenarios; elicit attitudes towards privacy, technology and trust)
➥3 focus groups, 23 Participants (9 female / 14 male; age 27y‐67y; av. age = 41,73, STD=14,8)

User‐ Requirements Examples• A device should provide feedback if third parties are able to read data during entry and transmission.
• The look and feel of a software or user interface should be consistent even among various devices.
• The adoption from IoT in daily life must be eco‐friendly and environmentally friendly.
• Security and privacy functions should be pre‐configured in a meaningful way. Users should be able to choose from pre‐defined policies which reflect common sense over the micro management of all policies for all use cases.
