Glossary of Terms Framework for Assistive Technology

Glossary of Terms	Definitions	Examples
Activity	The activity is the fundamental element of the HAAT model and is the overall goal of the assistive technology system. The activity is the process of doing something and it represents the functional result of human performance. Activities are carried out as part of our daily living, are necessary to human existence, can be learned, and are governed by the society and culture in which we live	·         3 basic performance areas: self-care, work/school, play/leisure ·         the activities an individual performs are determined by that person’s life role(s) ·         Activities can be broken down into smaller tasks … need to know what these are … helps determine points at which an individual may need assistance to accomplish activity.
Assistive Technology System	It consist of an assistive technology device, a human operator who has a disability, and an environment in which the functional activity is to be carried out.	Hearing assistive technology systems (HATS) are devices that can help you communicate with others. You may also hear them called assistive listening devices. HATS can be used with or without hearing aids or cochlear implants to make it easier to hear.
Contexts	The portion of the HAAT model that includes four major considerations: (1) setting, (2) social context, (3) cultural context, and (4) physical context.	where the activity is being performed ·         setting (environment) ·         social context (e.g. with peers, strangers, family) ·         cultural context (influences social s context) … will talk about the influence of culture on AT later ·         physical context (e.g. light, temperature, sound)
Extrinsic Enablers	An equivalent term for assistive technologies.	Provide basis that allows human performance to improve.
Function Allocation	The allocation of functions in any human/device system in which some functions are allocated to the human, some to the device, and some to the personal assistant services.	Function allocation (also known as task allocation) is a classic human factors method for deciding whether a particular function will be accomplished by a person, technology (hardware or software) or some mix of person and technology. To do this, the investigator considers error rates, fatigue, costs, hazards, technological feasibility, human values, ethical issues, and the desire of people to perform the function.
Human Activity Assistive Technology	A framework describing the major elements of an assistive technology system; consists of four parts: (1) activity, (2) context, (3) human skills, and (4) assistive technologies.	Typically used to describe the performance of a human in a given task (activity) in a given situation (context – environment).
Human Activity Assistive Technology Model	The HAAT model is made of four components: the human, the activity, the assistive technology and the context.	Human Performance Model Bailey (1989) was developed by human factors engineers and Psychologists … to assist in the design and application of technology. Framework for studying human performance in tasks involving technology.
Life  roles	Positions in society with responsibilities and privileges.	They relate roles to tasks, actions, and occupational performance.
Occupation	A job or profession.	Including administrative, banking, business, construction, customer service, education, entry level, finance, hospitality, management, retail, writing and more examples of resumes for employment.
Occupational Competence	It gives a dynamic context to the understanding of human abilities and how a person changes and adapts his or her engagement in activity in response to environmental demands and his own abilities.	·         observation of performance in the work environment ·         examining products of work ·         questioning the learner ·         discussing with the learner ·         use of others (witness testimony) ·         looking at learner statements ·         recognizing prior learning
Performances Areas	Activities of daily living, work and productive activities and play and leisure.	Activities of daily living including dressing, hygiene, grooming, bathing, eating, personal device care, communication, health maintenance, socialization, taking medications, sexual impression, responding to an emergence, and mobility.
Tasks	Small elements into which activities can be broken.	The activity of paying bills typically includes a series of tasks such as opening bill, reading the amount, writing a check for the appropriate amount, putting the check in the envelope with the bill, recording the check in the check register, sealing the envelope, placing a stamp on the envelope, and putting the envelope in the mailbox.
