As part of the TRAVEE (Virtual Therapist for Neuromotor Rehabilitation through Augmented Feedback) project we require a device for a precise tracking of the movements of the human hand. We concluded that the most appropriate for our purpose (due to its lightweight design and ease of use) would be a solution based on optical tracking. In this paper, we presented the way in which we evaluated two such optical tracking devices: Leap Motion and Intel RealSense. We used this method because we believe it fits the best our particular scenario.

This paper presents an approach to terrain synthesis from minimal-detail user-provided height-maps. There is no assumption regarding the level of detail provided, in order to allow users without access to powerful height-map tools and/or resources to generate usable terrain based on a self-provided crude feature plan. We present the issues stemming from a lack of detail in user input, notably sharp altitude increases and oversimplified feature edges, and proceed to elaborate on using the terrain synthesis algorithm to solve the issues and create a level of detail that more closely resembles realistic terrain models. The algorithm pipeline is presented and parameterized to show how the user can influence the resulting model.

This paper aims to illustrate a methodology for identifying and assessing a set of performance issues encountered in a particular web application, with impact on the usability level. Throughout this methodology, several visual techniques are determined and investigated by taking advantage of the functionalities offered by available performance monitoring tools such as JMeter and VisualVM. This way, the major performance concerns and their impact on the web application usability are easily determined. Therefore, by identifying the problematic parts of a system, corrective measures could be taken, particularly designed to operate on the root cause of the problem, thus leading to the targeted objective. Moreover, some performance improvement recommendations are further on presented in order to enhance the overall usability and the user experience, the actual goal of the research and development activities conducted. These performance concerns might be designed and implemented after fixing the critical parts causing usability problems and consequently, maximizing the user satisfaction and comfort when exploring the functionalities offered by a particular web application.
