“Despite the growing attention given to Web usability, little is understood
as to what Web design features contribute to Web users' attitude, a major
component of the usability of a Web site. This research investigates the
effects of interactivity level on Web user's attitude towards commercial Web
sites. It extends existing Web interface design and usability literature by
empirically examining the critical roles of interactivity. Three Web sites with
different levels of interactivity were compared in a controlled laboratory
experiment. Three eighteen-person groups completed each treatment. The
independent variable is the incremental levels of interactivity. The dependent
variables are satisfaction, effectiveness, efficiency, value, and attitude
towards the Web site. Results suggest that increased level of interactivity on
a Web site have positive effects on user's perceived satisfaction,
effectiveness, efficiency, value, and overall attitude towards a Web site.
Implications for Web site designers and researchers are discussed.”

“Virtual communities have been identified as the "killer applications" on the
Internet Information Superhighway. Their impact is increasingly pervasive, with
activities ranging from the economic and marketing to the social and
educational. Despite their popularity, little is understood as to what factors
contribute to the sustainability of virtual communities. This study focuses on
a specific type of virtual communities -- the virtual learning communities. It
employs an experiment to examine the impact of two critical issues in system
design -- information accessibility and community adaptivity -- on the
sustainability of virtual learning communities. Adopting an extended Technology
Acceptance Model, the experiment exposed 69 subjects to six different virtual
learning communities differentiated by two levels of information accessibility
and three levels of community adaptivity, solicited their feelings and
perceptions, and measured their intentions to use the virtual learning
communities. Results indicate that both information accessibility and community
adaptivity have significant effects on user perceptions and behavioural
intention. Implications for theory and practice are drawn and discussed.”

Chan, Hock C., Tan, Bernard C. Y. and Wei, Kwok Kee (1999): Three Important Determinants of User Performance for Database Retrieval. In International Journal of Human-Computer Studies, 51 (5) pp. 895-918.
“Three important factors that determine user performance during database retrieval are representation realism, expressive ease, and task complexity. Representation realism is the level of abstraction used when formulating queries. Expressive ease is the syntactic flexibility permitted when formulating queries. Task complexity is the level of difficulty of queries. A controlled laboratory experiment was conducted to assess the effects of these three factors on user productivity during database retrieval. The independent variables were representation realism (high versus low), expressive ease (high versus low), and query complexity (simple versus complex). The dependent variables were query accuracy and query time. Results show that all these three factors significantly affected user performance during database retrieval. However, their relative impact on query accuracy and query time differed. Moreover, these factors interacted in unique ways to moderate query accuracy and query time. Besides verifying prior empirical findings, these results offer several suggestions for future research and development work in the area of database retrieval.”

“A laboratory experiment was carried out to partially test the task-medium fit proposition in a GSS environment. Communication medium was varied using a face-to-face GSS and a dispersed GSS setting. Task type was varied using an intellective and a preference task. Group decision outcome variables of interest were (actual and perceived) decision quality, decision time, decision satisfaction, and decision process satisfaction. With the intellective task, there were no significant differences between face-to-face GSS and dispersed GSS groups for all group decision outcome variables. With the preference task, face-to-face GSS groups performed significantly better than dispersed GSS groups for all group decision outcome variables. These findings suggest that group decision outcomes in a GSS environment tend to be adversely affected when the communication medium is too lean for the task but not when the communication medium is too rich for the task. Consequences of providing groups with too rich and too lean a communication medium for their task are discussed. Implications of these findings, and other related results, for practice and for future revisions of media richness theory are explored.”

Tan, Bernard C. Y., Wei, Kwok Kee and Watson, Richard T. (1999): The equalizing impact of a group support system on status differentials. In ACM Transactions on Information Systems, 17 (1) pp. 77-100.
“This study investigates the impact of the electronic communication capability of a group support system (GSS) on status differentials in small groups. A laboratory experiment was used to answer the research questions. Three support levels were studied: manual, face-to-face GSS, and dispersed GSS. Two task types were examined: intellective and preference. Five dependent variables reflecting different aspects of status differentials were measured: status influence, sustained influence, residual disagreement, perceived influence, and decision confidence. The results show that manual groups had higher status influence, sustained influence, and decision confidence, but lower residual disagreement than face-to-face GSS and dispersed GSS groups. Preference task groups also produced higher status influence and sustained influence, but lower residual disagreement compared to intellective task groups. In addition, manual groups working on the preference task reported higher perceived influence than face-to-face GSS and dispersed GSS groups working on the same task. These findings suggest that when groups are engaged in activities for which status differentials are undesirable, a GSS can be used in both face-to-face and dispersed settings to dampen status differentials. Moreover, when a task amplifies status differentials, the use of a GSS tends to produce corresponding stronger dampening effects.”

“There have been many experiments comparing query languages. Their findings are difficult to combine as the experiments have used different settings and procedures. Before a meta-analysis combining the experiments, it is proposed that these differences be checked for any possible effect. The most important measure of user performance in these experiments is query accuracy, which has been determined using many different grading schemes. The different schemes are therefore checked for possible effects on hypothesis rejection. These grading schemes are applied to two sets of queries from two different experiments. The outcomes are examined to identify any effects resulting from the grading schemes. The results show that the experimental outcomes are robust and immune to the grading schemes.”

“Human-computer interaction models are integrated and enhanced to model the process of query writing, where users write queries to retrieve data from databases. A GOMS model detailing goals and operations is developed for the process of query writing using the query language SQL. Through protocol analysis, the model is compared with subjects' actual query retrieval processes.”

“Recent laboratory experiments have shown a strong tendency that database users can perform better at the conceptual level than at the logical level. The experiments measured users' performance for the tasks of database design and database retrieval. Besides database design and retrieval, the third major database task is update. User performance for updates has not been measured. With the widespread availability of databases, updates will be done frequently by end-users. This task is gaining in importance as a measure of the usability of a database system. An experiment was conducted to measure the effect of different abstraction levels on user performance for updates. A conceptual level group used the entity relationship model with an entity relationship query language KQL, while a logical level group used the relational model with the standard relational language SQL. Performance was primarily measured by the accuracy of the update query. Secondary measures of time and confidence were also taken. The results showed that updates at the conceptual level were 15.4% more accurate and required only 57.8% of the time taken for logical level updates. The differences were statistically significant with p values of less than 0.03.”
