ConclusionConclusion


Objectives concerning residential users

– Identify key factors in residential gateway context

– Identify main user activities

• Generic activities for all services

• Particular activity groups and interaction styles

– Provide recommendations for

• User acceptance

• UI design


Objectives concerning contractors

– Meaning of use

• Evaluate if the concept makes sense for contractors

• Anticipate potential acceptance

• Identify main issues to address in order to make the concept accepted


Objectives concerning contractors

– Analysis of practices

• Analyse contractor practices when installing and configuring a home automation system

• Anticipate activity evolutions

• Provide acceptance, design and HMI recommendations


Users

– Selection of representative subjects

• 18 residential service users

• 13 contractors (meaning of use diagnostic)

• 16 contractors (practices analysis)


Hypotheses elaboration (services, activities, interactions)

ScenariosMock-upsQuestionnaires

Simulated environment

Observation of scenario executionInterviews

Method for residential users

– Exploratory study


Method for contractors

– Meaning of use study (CAUTIC Method)

• Structured interviews around the presentation of the concept/product to be evaluated

– Separate UI for each service

• Clear and simple service access

• Need for combining some functions

• Lack of consistency


Objectives and MethodsObjectives and Methods





Meaning of use study (CAUTIC Method)

– 15 criteria evaluating if the user can:

• assimilate the new technique to its technical expertise

• integrate the innovation in its current practices

• appropriate the innovation to his private and professional identity

• adapt the innovation to his environment


Gateway installation and assistance service concepts

– General results

• Concepts difficult to understand

• Confusion between different levels



– Difficulties
