Design, development, and evaluation of a virtual reality game-based application to support computational thinking.

Computational thinking (CT) has become an essential skill nowadays. For young students, CT competency is required to prepare them for future jobs. This competency can facilitate students' understanding of programming knowledge which has been a challenge for many novices pursuing a computer science degree.

Analysis of disruptive events and precarious situations caused by interaction with neurosurgical microscope.

Background: Developments in micro-neurosurgical microscopes have improved operating precision and ensured the quality of outcomes. Using the stereoscopic magnified view, however, necessitates frequent manual adjustments to the microscope during an operation.

Method: This article reports on an investigation of the interaction details concerning a state-of-the-art micro-neurosurgical microscope.

Validating the Restricted Focus Viewer: a study using eye-movement tracking.

Investigation of cognitive processes and visual attention during problem-solving tasks is an important part of understanding human reasoning. Eyetracking technology has proven to have many benefits in revealing visual attention patterns. However, the high price of accurate eyetrackers and the difficulties associated with using them represent major obstacles to their wider application.
