Some unusual primitives in the mira graphical extension of PASCAL

The MIRA system is a very general graphics system which may be useful for almost anyone interested in the production of drawings. The system allows the user to create, save, retrieve, modify and delete any kind of drawing: e.g. free-hand drawings, drawings based on geometrical primitives, algorithmic drawings, data plots, texts. Two-dimensional and three-dimensional drawings can be manipulated. The MIRA system is based on two graphical PASCAL extensions MIRA-2D and MIRA-3D. Two interactive graphical editors GRAFEDIT (two dimensions) and HORIZON (three dimensions) allow the non-specialist user to build complex drawings easily.After an overview of the MIRA system, we present the most unusual primitives, which have been developed for use with this system. These primitives can be divided into different classes: graphical types, figure algebra primitives, figure measure functions, figure recognition predicates, image transformations and animation primitives.     

Application integration: Constructing composite applications from interactive components

Creating new applications by integrating user interface and application components is a relatively new idea which is currently of wide interest. A significant part of this problem is clearly defining the separation between user interface and application components. This paper proposes a new design methodology based on the concept of an abstract data view (ADV), a structuring method which cleanly defines this separation. A number of examples of composite interactive documents, ones which could contain several different user interfaces with entities such as text, calculations, drawings and possibly even multi-media presentations, illustrate the ADV concept. These examples lead naturally to the introduction of the concept of hole, a user interface area in a composite interactive document which is managed by an external program, and uses ADVs. Prototypes of a number of systems supporting ADVs and holes are currently running in our laboratory.     

Smart Scribbles for Sketch Segmentation

We present ‘Smart Scribbles’—a new scribble‐based interface for user‐guided segmentation of digital sketchy drawings. In contrast to previous approaches based on simple selection strategies, Smart Scribbles exploits richer geometric and temporal information, resulting in a more intuitive segmentation interface. We introduce a novel energy minimization formulation in which both geometric and temporal information from digital input devices is used to define stroke‐to‐stroke and scribble‐to‐stroke relationships. Although the minimization of this energy is, in general, an NP‐hard problem, we use a simple heuristic that leads to a good approximation and permits an interactive system able to produce accurate labellings even for cluttered sketchy drawings. We demonstrate the power of our technique in several practical scenarios such as sketch editing, as‐rigid‐as‐possible deformation and registration, and on‐the‐fly labelling based on pre‐classified guidelines.     

Supporting subject matter annotation using heterogeneous thesauri: A user study in Web data reuse

We performed a user experiment in which museum professionals used vocabularies from the Web for annotating the subject matter of museum objects. In this paper, we study the requirements on the underlying RDF dataset, search algorithms and user interface design in a real world setting. We identify the advantages of reusing vocabularies from the Web and discuss how and to what extent the disadvantages can be overcome. The study is performed at the Print Room of the Rijksmuseum Amsterdam, where currently a large collection of prints, photographs and drawings is being catalogued. We report on the analysis of the current practice of professional cataloguers, the iterative design of an annotation tool and a qualitative evaluation of this tool with a user experiment in a realistic annotation environment. We discuss our findings in terms of their impact on the RDF data, the semantic search functionality and the user interface.

Investigating the affective quality of interactivity by motion feedback in mobile touchscreen user interfaces

Emotion is a key aspect of user experience. To design a user interface for positive emotional experience, the affective quality of the user interface needs to be carefully considered. A major factor of affective quality in today's user interface for digital media is interactivity, in which motion feedback plays a significant role as an element. This role of motion feedback is particularly evident in touchscreen user interfaces that have been adopted rapidly in mobile devices. This paper presents two empirical studies performed to increase our understanding of motion feedback in terms of affective quality in mobile touchscreen user interfaces. In the first study, the relationships between three general motion properties and a selected set of affective qualities are examined. The results of this study provide a guideline for the design of motion feedback in existing mobile touchscreen user interfaces. The second study explores a new dimension of interactivity that is the Weight factor of Laban's Effort system. To experiment the Weight factor in a mobile touchscreen user interface, a pressure sensitive prototype was developed to recognize the amount of force applied by the user's finger action. With this prototype, the effects of implementing pressure requirements on four different types of user interfaces were examined. Results show that implementing the Weight factor can significantly influence the affective quality and complement the physical feel of a user interface. The issues to consider for effective implementation are also discussed.     

TUIs vs. GUIs: comparing the learning potential with preschoolers

In an effort to better understand the learning potential of a tangible interface, we conducted a comparison study between a tangible and a traditional graphical user interface for teaching preschoolers (In Portugal, children enter preschool at the age of three and they attend it till entering school, normally at the age of six) about good oral hygiene. The study was carried with two groups of children aged 4 to 5 years. Questionnaires to parents, children’s drawings, and interviews were used for data collection and analysis and revealed important indicators about children’s change of attitude, involvement, and preferences for the interfaces. The questionnaires showed a remarkable change of attitude toward tooth brushing in the children that interacted with the tangible interface; particularly children’s motivation increased significantly. Children’s drawings were used to assess their degree of involvement with the interfaces. The drawings from the children that interacted with the tangible interface were very complete and detailed suggesting that the children felt actively involved with the experience. The results suggest that the tangible interface was capable of promoting a stronger and long-lasting involvement having a greater potential to engage children, therefore potentially promoting learning. Evaluation through drawing seems to be a promising method to work with preliterate children; however, it is advisable to use it together with other methods.
