Most work on model-based cross-platform user interface development is based on an assumption that the user interfaces on the different platforms should be as similar as possible. Much work on mobile user interfaces claim the opposite – that user interfaces on a mobile platform should have features not applicable on a stationary one and vise versa. Exploiting contextual information in user inter...

Most design and evaluation of software tools is based on the intuition and experience of the designers. Software tool designers consider themselves typical users of the tools that they build and tend to subjectively evaluate their products rather than objectively evaluate them using established usability methods. This subjective approach is inadequate if the quality of software tools is to impr...

The dataset selected for this assignment comes from the set of Amazon reviews for automotive products that can be found at the Stanford University SNAP website [1]. The dataset is formatted as a JSON document where each example is a user review for a product. The format and information represented by each example is shown in Table 1. The dataset consists of 188,728 user reviews of automotive pr...

We present the development of a new graphical user interface driven molecular modeling, editing and visualization tool called Tiamat. Tiamat addresses the challenge of how to efficiently model large and complex DNA nanostructures. We describe the three major components of our system. First, we discuss design guidelines and data structures that form the basis of flexible and large-scale editing....

Users spend hours making selections with ineffective tools, we therefore examine selection methods for efficiency in various touch trials. In a preliminary study three alternative selection methods were identified, we compared these to a smart selection tool. The study showed that a single selection method was the fastest; however, when the amount of targets increased, a multiple selection tool...

One of the most exciting aspects of shape modeling is the development of new algorithms and methods to create unusual, interesting and aesthetically pleasing shapes. In this paper, we present an interactive modeling system for generating freeform surfaces using a 2D user interface. In this paper, we firstly interpret the given 2D curve to be the projection of the 3D curve that has the minimum c...

The design of robust new interfaces that process conversational speech is a challenging research direction largely because users’ spoken language is so variable, which is especially true of children. The present research explored whether children’s response latencies before initiating a conversational turn converge with those heard in the text-to-speech (TTS) of a computer partner. A study was ...

Freeform features can be regarded as key elements of shape modeling. Commonly, features are defined, controlled and computed using parameters. In this paper we propose a feature formulation strictly based on the parameterization, as a mapping from an arbitrary set to some domain of interest. This formalism accommodates many of the common representation forms and in addition allows 1) the unifor...

We investigate using the PARADISE framework to develop predictive models of system performance in our spoken dialogue tutoring system. We represent performance with two metrics: user satisfaction and student learning. We train and test predictive models of these metrics in our tutoring system corpora. We predict user satisfaction with 2 parameter types: 1) system-generic, and 2) tutoringspecifi...

What will social media sites of tomorrow look like? What behaviors will their interfaces enable? A major challenge for designing new sites that allow a broader range of user actions is the difficulty of extrapolating from experience with current sites without first distinguishing correlations from underlying causal mechanisms. The growing availability of data on user activities provides new opp...
