Abstract
Today, User Experience (UX) and Human-Computer Interaction (HCI) tools can provide a competitive advantage that might be key of a company’s business success or failure. In this paper, the awareness and use of these tools among start-ups is examined with a survey. The results hint that there is lots of room for improvement in terms of raising awareness and adoption of tools that help companies deliver better experiences through their products.

Abstract
Programming courses are very important and challenging part of computer experts’ education process. However, abstract nature of these courses makes them rather difficult for most students. In order to increase students’ motivation and level of comprehension regarding programming an approach that includes less abstract presentation of programming concepts using visualization techniques is proposed and implemented through the tool SortExpert that is designed to help the students to cope in a more suitable and easier way with various sorting algorithms. Discussion about the effectiveness of existing visualization tools and research about the evaluation and acceptance of SortExpert are also presented.

Abstract
This paper proposes an improved approach for LiDAR data visualization in terms of rendering quality. The method uses adaptive point-scaling for dealing with variations in data densities, while the contrasts of rendered objects are improved with weighted color mapping. In the former case, points’ distances from the observer are used to estimate their optimal rendering sizes. In the latter case, points are colored based on height attributes and increasing visual fidelity a point’s color is weighted using that point’s intensity information. Common image quality matrices, as well as conducted user study, confirm the improvements of the visualization.

Abstract
In this paper we present a system for touchless interface using Kinect sensor. The system can be used for general purpose interaction with existing applications. We show a case study implementation for use with web-browser where user can interact with the content using gestures. We also present implementation of the game that uses presented system for handling interaction with the user. We also present advantages and disadvantages of such framework and give possible solutions for some of the problems.
