TLDR
It is concluded that empirical studies of the unique qualities of man-machine interaction as distinct from general human discourse are required for the development of user-friendly interactive systems.Abstract:
Current approaches to the development of natural language dialogue systems are discussed, and it is claimed that they do not sufficiently consider the unique qualities of man-machine interaction as distinct from general human discourse. It is concluded that empirical studies of this unique communication situation are required for the development of user-friendly interactive systems. One way of achieving this is through the use of so-called Wizard of Oz studies. The focus of the work described in the paper is on the practical execution of the studies and the methodological conclusions drawn on the basis of the authors' experience. While the focus is on natural language interfaces, the methods used and the conclusions drawn from the results obtained are of relevance also to other kinds of intelligent interfaces.read more

Architectures for Shared Control of Vehicle Steering
TL;DR: A system model outfitted with the features required to describe modulating impedance as a means to dynamically allocate authority is developed and a platform designed to support experiments in control sharing with dynamic allocation of authority between two humans is described.

Visualising interactive graphics design for testing with users
TL;DR: The pilot study indicates that a refined Ozlab could be used by inexperienced designers for testing their own ideas, and the fact that requirements of interactivity thus can be visualised by laymen will have implications for the design of requirements specification for multimedia products.

Expectations vs. actual behavior of a social robot: An experimental investigation of the effects of a social robot's interaction skill level and its expected future role on people's evaluations.
TL;DR: Overall, in case of an actual interaction with a social robot, the robot’'s behavior is more decisive for people’s evaluations of it than their expectations or individual backgrounds.

Conduct by wire - maneuver catalog for semi-autonomous vehicle guidance
TL;DR: In this paper, the authors describe the methodology for the development of a maneuver catalog that reflects user expectations, and a three-step procedure is proposed that includes identification of relevant decision points during a driving task, clustering of maneuvers in order to reduce the maneuver catalog complexity, and validation with the Wizard of Oz technique.

Simulating pedagogical agents in a virtual learning environment
Silje Jondahl,Anders I. Mørch +1 more
TL;DR: It is indicated that agents can have an effect on collaboration by making users aware of collaboration patterns (division of labour, explicit roles, etc.) and by creating focus shifts in the users' interaction.

The development of communication skills: modifications in the speech of young children as a function of listener
Marilyn Shatz,Rochel Gelman +1 more
TL;DR: This paper found that the 4-year-old adjusted his speech with regard to the changing capacities of different-aged listeners, and the younger the 2-year old, the greater was the observed speech adjustment.

Cross-linguistic differences in parsing: Restrictions on the use of the Late Closure strategy in Spanish ☆
Fernando Cuetos,Don C. Mitchell +1 more
TL;DR: The results throw doubt on the suggestion that the Late Closure strategy is favoured (in English) mainly because it is efficient in information processing terms and suggest that different languages make use of parsing strategies in an essentially arbitrary way.

TL;DR: The “Wizard of Oz” technique for simulating future interactive technology and a partial taxonomy of such simulations is reviewed and a general Wizard of Oz methodology is suggested.
