Abstract

People in industrial societies carry more and more portable electronic devices eg smartphone or console with some kind of wireless connectivity support Interaction with autodiscovered target devices present in the environment eg the air conditioning of a hotel is not so easy since devices may provide inaccessible user interfaces eg in a foreign language that the user cannot understand Scalability for multiple concurrent users and response times are still problems in this domain In this paper we assess an interoperable architecture which enables interaction between people with some kind of special need and their environment The assessment based on performance patterns and antipatterns tries to detect performance issues and also tries to enhance the architecture design for improving system performance As a result of the assessment the initial design changed substantially We refactorized the design according to the Fast Path pattern and The Ramp antipattern Moreover resources were correctly allocated Finally the required response time was fulfilled in all system scenarios For a specific scenario response time was reduced from 60 seconds to less than 6 secondsThe research described in this paper arises from a Spanish research project called INREDIS INterfaces for RElations between Environment and people with DISabilities INREDIS is led by Technosite and funded by CDTI Industrial Technology Development Centre under the CENIT National Strategic Technical Research Consortia Programme in the framework of the Spanish government’s INGENIO 2010 initiative The opinions expressed in this paper are those of the authors and are not necessarily those of the INREDIS project’s partners or of the CDTIJosé Merseguer has been supported by CICYT DPI201020413 and GISED partially cofinanced by the Aragonese Government Ref T27 and the European Social FundWe would like to thank José Antonio Gutiérrez for his work in the experimental tests and Marta Alvargonzález Esteban Etayo and Fausto Sainz for their help Last but not least the authors thank the anonymous reviewers for their valuable help to improve this workIt requests to the Interoperability Gateway module the current state of each device the getState method The Interoperability Gateway obtains this information no matter whether the device is exposed as a Web service or for UCH Target in a transparent fashion
