As mobile devices are becoming ubiquitous, regularly interacting with a variety of user interfaces (UIs) is common aspect daily life for many people. To improve the accessibility these and to enable their usage in settings, building models that can assist users accomplish tasks through UI vitally important. However, there several challenges achieve this. First, components similar appearance hav...

We present initial results of a study on the effects of biomechanical influences in the human hand on the natural pen stroke. A geometric model suggests that a user interface, curved to match the natural motion of the hand, would be more appropriate than a user interface aligned with the horizontal and vertical boundaries of the display device. While our results confirm the presence of a curve ...

We describe a design approach, Tangible Augmented Reality, for developing interfaces for supporting face-to-face collaboration. By combining Augmented Reality techniques with Tangible User Interface elements, we can create interfaces in which users can interact with spatial data as easy as real objects. Tangible AR interfaces remove the separation between the real and virtual worlds and so enha...

In this paper, we present the idea to use natural language as the user interface for programming tasks. Programming languages assist with repetitive tasks that involve the use of conditionals, loops and statements. This is what is often challenging users. However, users can easily describe tasks in their natural language. We aim to develop a Natural Language User Interface that enables users to...
