This paper presents a hand-based interaction approach for grabbing and manipulating virtual objects within immersive virtual environments. Considering the stimulusresponse of humans, interacting with objects is easier if depth information is provided by stereoscopic vision. However, most people are used to work in monoscopic virtual environments. Therefore, we propose a case study, to analyze if an interaction approach using stereoscopic vision, compared to a conventional monoscopic vision, results in a higher user acceptance and stimulus-response correspondence.Our interaction approach is based on a robust and fast running 3D hand-and head-tracking provided by Microsoft's Kinect. We present a simple non-collision-based method for grabbing and manipulating objects within a 3D virtual environment. By tracking the head, the user is able to move within the environment and interact depending on his current position. The use of stereoscopic vision allows a natural and instinctive hand interaction with the augmented object.Finally, the experimental results and studies show how the use of stereoscopic vision improves the mental mapping and thus the user acceptance and stimulus-response correspondence in consideration of using the here presented interaction approach.

The shortage of highly-skilled ICT (information and communications technology) workers remains a serious and global concern. This paper reports on how to attract more computer science majors to job fields within ICT that are especially critical to economic growth, rather than how to solve the overall shortage. A qualitative preliminary study found that certain software-related aspects might play an important role when picking a job field. In order to generalize and validate these findings an online survey based on the Social Cognitive Career Theory was conducted. The data were analyzed and show that the software used in a prospective job does in fact have a positive influence on computer science majors' career choice when a technical usage of the software is pursued. A direct correlation exists between usage frequency of a software product and the willingness to take on a job in which the software is used. A modern user interface is an advantage when attracting computer science majors to specific job fields but other characteristics such as good functionalities and ease of learning seem to affect career choice much more. Further research will be required to determine which characteristics of a software are decisive.
