DOCTORALTHESIS, CERTEC 2:2009
The purpose of the research presented in this thesis is to enhance the field of accessibility to include a multitude of perspectives. Based on cultural-historical activity theory (CHAT), it analyzes how human, artifactual and natural factors impact an individual’s possibilities to act in concrete situations that are part of a systemic whole.
The thesis presents two main results:
An enhanced accessibility encompassing:
Epiaccessibility, accessibility’s spirit of the times, stands for how
experiences of activities alter accessibility capacities, learning, expectations,
attitudes, trust, demands and denials of the individual and her human,
artifactual and natural environments.
Lived accessibility, which includes the anticipations and the
experienced conditions of a person to be able to do what she wants in a concrete
situation.
Planned accessibility, which consists of all the accessibility factors
that can be created beforehand based on plans, guidelines and principles.
The Activity Diamond, a model for accessibility:
The Activity Diamond portrays a human activity system, where the subject-object
relation is mediated and thus influenced by the human, artifactual and natural
environments. The model is based on four interrelated sets of factors and is
situated in time and place. Different actors with different activity systems may
be involved. The model can be also used longitudinally in time.
The thesis is based on a series of explorative studies in which the analysis unit is shifted from impairments and discriminatory factors in society to unique individual activity systems where humans, artifacts and nature together influence accessibility.
