• How user’s information is collected?

QuestionnairesObservation

End users complete adapted questionnaires during the use of AAL system.

Naturalistic observation involves recording the subjects behavior in their AAL environment.

Questionnaires collect factual information about individuals

Collecting data from user actions in the environment
