Notas del editor
- Title note: …not understanding assistive systems as a software system, but a community and elements inside an assistive or AAL environment.
- From the Ambient Assisted Living paradigm we have designed a methodology and implemented a software tool to be integrated into a AAL system or environment. The aim of this is to facilitate the analysis of several clinical measures and user assessments. The conceptual methodology as (leer) And the software system to guide (leer)
- This methodology is close to a framework for the analysis of three relevant aspects (level in execution of IADL, stress and QoL) and also user experience in an AAL environment, such as elderly people (identified as primary user) and carers (secondary users) by using interactive systems at their home. The methodology helps in the gathering of requirements of an AAL system based on Psychological fundamentals and context-aware elements. Based on this methodology, we can create an AAL software systems to get all of that information and perform the corresponding analysis. Even that software could be distributed into several software components or applications.
- But, how the relevant information of users is collected?. The methodology identifies two sources of information: By means of Naturalistic observation (important to get awareness) And with questionnaires and surveys In the first case, (leer) and in case of questionnaires (leer). These data can be used for analysis tasks, for example, by researchers.
- The methodology defines several interrelated submodels: Models to represent knowledge aspects: Psychological and sociological model, Conceptual model Models to represent the environmental actions: Task model, Interaction model Model to guide developers in the development of analysis tools: Developer’s model. Besides, the methodology has different execution stages (some linked to the sub-models). Thus, we have: 3 stages related to collecting information: Observation (to identify user problems), planning (strategies to solve these problems)) and design (development of sub-models). 1 stage regarding the development of the analysis software system based on the theorical framework. 3 stages regarding the deployment and evaluation of the developed system.
- We have develop an analysis software system for suporting users (elders and carers) in the assessment of these aspects (stress, QoL and Instrumental Activities of Daily Living level). Using the mentioned methodological specifications. The context is the following: Elderly people…(leer)
- The implemented analysis tool is able to manage the following functionalities: 1.Users: Each user of the AAL system has a role to determine his/her privileges. Carer are associated with researchers, and elders are associated with carers. (This is an example of users in the web application) 2. Actions: (leer)
- This is an example of action gathering. In this case, an elder of a specific AAL mobile application touches a button, then this action is saved into a database, and it is available for the analysis software tool. This information can be shown in a carer or researcher application, even with statistical data. Also, this is a valid option to get awareness from a distributed AAL system.
- The other data source defined in the methodology and taken into account in the software system is the information from tests and questionnaires. For example, these tests can be created by researchers and completed by carers in the corresponding software tool, in order to measure IADL, carer stress and QoL levels. There are 2 types of tests, standard and interactive. Each test consists of a group of blocks of questions and each block consists of a set of questions (exclusive, multiple or text). In case of interactive test, questions can be linked with other questions. The followed path determines the results of the test. This is an example of an interactive test regarding the telephone use. However, the methodology does not define how the questionnaires should be implemented, this corresponds to the developer. Here we have a screen capture with a part of a questionnaire. These tests are assigned by researchers, who can create general templates of questionnaires and analyze the results.
- Carers can complete assigned questionnaires and get feedback about theirselves and the elders they take care. If the questionnaires have a score, this is used to determine one or more recommendations by experts. This is a screen capture of a recommendation focused on a carer who completed the interactive test. This recommendation is a basic feedback to the user. However, partial results of the test are saved into the system for detailed analysis.
- All the information and application parameters of the analysis tool can be managed from an administration tool. This includes the administration of: (leer)
- In this work we have presented a methodology to guide in the analysis of IADL, carer stress and QoL aspects, taking into account the following elements: (leer). This methodology is close to a framework to facilitate the development of analysis sofware tools We have develop a prototype of analysis tool based on this methodology to be deployed, in this case, in an elderly AAL context, divided into 3 parts or modules (leer). As ongoing work, we are evaluating a group of elders and carers in that elderly context to determine the behaviour, acceptance and validation of the system and the methodology.
