Natural User Interfaces (NUI) are supposed to be used by humans in a very logic way. However, the run to deploy Speech-based NUIs by the industry has had a large impact on the naturality of such interfaces. This paper ...

Information and Communication Technologies, and specifically e-Government developments, occupy a relevant position in the national agenda of many countries worldwide. But development of such projects requires a careful ...

Ambient Intelligence and Ubiquitous Computing are carrying the world to a reality where almost every object interacts with the environment, either via sensors or actuators, and users must learn how to interact with such ...

This paper describes the design and evaluation process of two mobile programming assistance tools that allow children in the early childhood to develop programs and execute them using robots. The tools are called TITIBOTS ...

Robotics, combined with computer science and human-centered studies, can have a substantial impact in areas such as education and innovation. Robots have proven to be a good tool to gain and maintain users’ involvement in ...

A non-humanoid robot is used to assist in an educational workshop of Quality Assurance and DevOps. The goal of this research was to determine the level of engagement shown by students of computer science in a presentation ...

In Ubiquitous Computing, augmented objects refer to those elements of the real world which have been provided with computational capabilities to meet a specific need. Meanwhile, Collaborative Writing Environments (CWE) ...

At this time, great effort is being directed toward developing problem-solving technology that mimics human cognitive processes. Research has been done to develop object recognition using Computer Vision for daily tasks ...

People tend to value their privacy, but are usually unaware about the extent to which their personal information is exposed through ordinary data available online. In this paper we describe an experience in which a group ...

Traditional web interfaces often rely on keyboard/mouse input to work. This characteristic forces people with reduced mobility to adapt or do not use the applications at all. This paper proposes a prototype to increase web ...
