Methods for design and evaluation of interactive applications are not readily applicable to mobile services. By modifying an existing paper prototyping method we evaluated a mobile social service for providing user-based tips in a shopping mall. The evaluation showed that tips can be pushed to users and that they can accept that a complex user interface is presented on a small screen. Although ...

One of the main challenges that has come to face system designers in the last decade had been to accomplish an adequate characterisation of the social properties of the work settings into which systems have to fit. Grudin (1990:261) describes this as an "outward movement of the computer's interface to its external environment, from hardware to software to increasingly higher-level cognitive cap...

dy of cultural efsects on the reliability of objective and ztive usabili@ evaluation of software user interfaces is ted in this paper. Subjects comprised actual users Ted in a real system development proj’ect. The results aed indicated that cultural effects exist and exerted a g influence on the outcome of user interface ation. Implications of the findings for practitioners iscussed in the pape...

Low viscosity (<100 cSt) silicon oil droplets are placed on a high viscosity (1000 cSt) oil bath that vibrates vertically. The viscosity difference ensures that the droplet is more deformed than the bath interface. Droplets bounce periodically on the bath when the acceleration of its sinusoidal motion is larger than a threshold value. The threshold is minimum for a particular frequency of excit...

The Airbus Visual Line (AVL) project, now deployed on the A380 assembly line, was propelled by the desire to foster collaboration and coordination among aeronautical Final Assembly Line teams while going beyond the simplistic – repressive concept of “andon boards” (Monden, 1993). We introduced an environment composed of large public displays and semi-public interfaces to support this collaborat...

Successful use of a hand-held tool requires overcoming the rotational inertia of the hand-plus-tool system. Where an object is grasped affects this rotational inertia. Appropriate choice of grip position may be crucial in the safe, effective, and efficient control of a hand-held tool. In 3 experiments, the authors investigated how choice of grip position on a tool was constrained by task demand...

Transactive memory system (TMS) refers to the knowledge storage in individual's memory. Members in the organization rely on the knowledge network, and they have to utilize their knowledge and expertise to achieve shared goals. TMS consists of three parts: specialized team knowledge, mutual trust between members, and organized task processes (Lewis, 2003). Past research focused on the group leve...

Depressurization and pressurization streams in industrial systems constitute a work exchange network (WEN). In this paper, a novel graphical approach for targeting energy conservation potential of a WEN is proposed. Through constructing the composite work curves in the pressure-work diagram and assuming all of the mechanical energy of the depressurization streams is recovered by expanders, the ...

The wildland urban interface (WUI) delineates the areas where wildland fire hazard most directly impacts human communities and threatens lives and property, and where houses exert the strongest influence on the natural environment. Housing data are a major problem for WUI mapping. When housing data are zonal, the concept of a WUI neighborhood can be captured easily in a density measure, but var...

Multi-view editing is useful in many situations where users of a software application want to see and interact with different representations of the same information. This paper describes a new approach to keeping free-edited multiple textual and graphical views of information consistent. Descriptions of changes to information items are displayed in various ways in the multiple views of these i...
