Improving service matching and selection in ubiquitous computing environments: a user study

Abstract

In large ubiquitous computing environments it is hard for users to identify and activate the electronic services that match their needs. This user study compares the newly developed service matcher system with a conventional system for identifying and selecting appropriate services. The study addresses human factors issues such as usability, trust and service awareness. With the conventional system users have to browse a hierarchical list of currently available services and activate the service that they think satisfies their current needs. With the service matcher users just enter their current need using natural language, after which a wizard, emulating an existing service matcher algorithm, searches for and activates a matching service based on the given need and the users' location and gaze direction. This study shows that with the hierarchical list, only 66% of the tasks are solved correctly, and females score significantly worse than males. With the service matcher, the performance increases significantly to 84% correctly performed tasks and the gender difference disappears.

iCompose: context-aware physical user interface for application composition

“…Overall, users from both groups gave positive remarks on the idea of connecting a game partner by making a handshake. Called 'human service discovery', this approach dominates in usability over classical search techniques in ubiquitous environments, as confirmed by Lindenberg et al [30]. Control.…”

“…For instance, Chantzara et al [13] and Takemoto et al [63] studied service provisioning issues, Bertolino et al [5] and Butford et al [10] tackled service validation and trust issues, Kalasapur et al [26] targeted optimization of service communication paths, Nakazawa et al [39] focused on automatic generation of application code, Rigole et al [51,52] addressed distributed user interface deployment, Mungellini et al [36] applied composition to fast-prototype multimodal applications, Sousa et al, Ben Mokhtar et al, Cang et al and Lindenberg et al [4,12,30,61] introduced specification languages for querying and describing application composition, and finally, Sousa et al [62] and Paluska et al [43] introduced design styles for developing adaptive applications through composition. A number of authors surveyed application composition approaches in ubiquitous computing.…”

An efficient algorithm for partially matched services in internet of services

“…There are number of approaches for discovery and selection of services in IoT environment [1,[5][6][7]. However, discovery and selection is a challenging process especially when there is a list of available services with similar functionality but different QoS parameters such as execution time, security, and cost in line with the increasing number of available services.…”

A Multi Dimension Service Trust Model in Social Network

“…Kalepu summarized the attributes of quality of service (QoS) required in web service selection [8]. Lindenberg analyzed trust relationship between human societies, and proposed the service selection algorithm based on trust relationship [9]. However, a large-scale system has sparse direct relationship.…”
