Designing generation Y interactions:The case of YPhone

Background With an increasing number of products becoming digital,mobile,and networked,paying attention to the quality of interactions with such products is also becoming more relevant.Although the quality of such interactions has been addressed in several scientific studies,little attention has been paid to their implementation in real life and everyday contexts.Methods This paper describes the development of a novel office phone prototype,called YPhone,which demonstrates the application of a specific set of Generation Y interaction qualities(instantaneous,playful,collaborative,expressive,responsive,and flexible)in the context of office work.The working prototype supports office workers in experiencing new types of interactions.It was set out in practice through a series of evaluations.Results We found that the playful,expressive,responsive,and flexible qualities incur greater trust than the instantaneous and collaborative qualities.Such qualities can be grouped,although this may differ for different evaluated products,and researchers must be cautious about generalizations.Conclusions The overall evaluation was deemed positive,with some valuable suggestions provided regarding its user interactions and features.

Exploring Some Tactics on How to Make English Lessons More Effective

This paper explores some effective tactics on the teaching of English. It starts with the introduction of the importance of learning English, then it reveals the qualities and useful strategies that a teacher of English should master if he or she wants to make his or her lessons successful. It also conducts the analysis of how these tactics interact in the classroom teaching. The paper concludes that examining effective ways of teaching is useful in helping teachers either in their academic field or in their professional development.

Multi-parameter joint optimization for double-strip high-speed pantographs to improve pantograph-catenary interaction quality

The significant increase in speed of high-speed train will cause the dynamic contact force of the pantograph-catenary system to fluctuate more severely,which poses a challenge to the study of the pantograph-catenary relationship and the design of highspeed pantographs.Good pantograph-catenary coupling quality is the essential condition to ensure safe and efficient operation of high-speed train,stable and reliable current collection,and reduction in the wear of contact wires and pantograph contact strips.Among them,the dynamic parameters of high-speed pantographs are crucial to pantograph-catenary coupling quality.With the reduction of the standard deviation of the pantograph-catenary contact force as the optimization goal,multi-parameter joint optimization designs for the high-speed pantograph with two contact strips at multiple running speeds are proposed.Moreover,combining the sensitivity analysis at the optimal solutions,with the parameters and characteristics of in-service DSA380 highspeed pantograph,the optimization proposal of DSA380 was given.
