The goal of our research is to combine the power of stroke-based sketch recognition with the flexibility and ease of use of a piece of paper. In this paper we will present preliminary results of our algorithm integrated with an online sketch recognition system built with LADDER. We have also presented a comparison of our paper based interface with tablet based sketching interface. ACM Classific...

Today, there are numerous software patterns for the software engineering of User Interfaces through interaction object classes that can be automatically retargeted to different graphical environments. Such methods are usually deployed in implementing multi-platform User Interface libraries, delivering Application Programming Interfaces (APIs) typically split in two layers: (a) the top layer, en...

Graphical user interfaces have become very popular for database systems since they increase the usability of these applications. The functionality and ease-of-use of the graphical user interface, however, depend on the expressiveness and complexity of the underlying data model. With the advent of new database technology based on powerful data models like the object-oriented data model new chall...

Adaptive Interfaces: Do People Want Them? Automatic adaptation of user interfaces is a contentious area. Proponents (e.g., [1]) argue that it offers the potential to optimize interactions for a user’s tasks and style while critics (e.g., [4]) maintain that the inherent unpredictability of adaptive interfaces may disorient the user, causing more harm than good. Surprisingly, however, there is ve...

Despite the apparent advantages of and recent advances in the use of visualization in engineering design and optimization, we have found little evidence in the engineering literature that assesses the impact of fast, graphical design interfaces on the efficiency and effectiveness of engineering design decisions or the design optimization process. In this paper we discuss two examples—the design...

-With the availability of OpenGL ES and low-power specialized graphics hardware, 3D graphics are increasingly incorporated into software for mobile devices. However, there is only a small body of research regarding effective user interfaces in this environment. The goal of this study is to analyze the effectiveness of several 3D mobile interfaces by conducting an experimental survey. Study part...

This paper presents TJass, a smart board that extends regular card playing with computational supports, without modifying players’ habits. The article first presents the functionalities, in particular the learning by trial assistant, and architecture of TJass and further details the hardware implementation and problems encountered. The article concludes with users’ satisfaction comments. ACM Cl...

In this report, different vision-based approaches to solve the problem of hand pose estimation are reviewed. The first three methods presented utilize random forest, whereas the last tackles the problem of pose estimation of two strongly interacting hands. Lastly, an outlook at the future of the field is given. ACM Classification: H5.2 [Information interfaces and presentation]: User Interfaces....

We present a preliminary exploration of information visualization techniques for extracting social and emotive aspects of movement. Our glyph-based technique visualizes particular characteristics of a motion path or interaction sequence between two characters. In this paper we detail our efforts of creating glyphs that extract and expose underlying emotive and social aspects of the collocated p...

The majority of existing work in music information retrieval for audio signals has followed the content-based query-by-example paradigm. In this paradigm a musical piece is used as a query and the result is a list of other musical pieces ranked by their content similarity. In this paper we describe algorithms and graphical user interfaces that enable novel alternative ways for querying and brow...
