“…In this case, they were able to choose and keep a top viewing angle on the tissue while moving their head to manipulate the needle correctly. Indeed, its design, based on Guiard (1987) principles for bimanual interaction, proved to have a beneficial impact on dominant-hand's precision, which is inline with previous results (Bertrand et al, 2015). After the needle penetrated inside the tissue, and during the needle insertion towards the target, an inclined viewing angle was necessary.…”

“…Interaction fidelity is more important to guarantee the knowledge transfer from the simulator to the real world (Drews and Bakdash, 2013). Moreover, multidisciplinary iterative design methods suggest that building efficient interactive systems requires focusing on the design of effective interactions for them (Johnson et al, 2011;Chellali et al, 2012;Yang et al, 2012;Barkana-Erol and Erol, 2013). Therefore, focusing on the interaction component of the fidelity of the simulator appears as a key issue to address to build efficient virtual simulators.…”

Recently, virtual reality (VR) technologies started gaining momentum in surgical simulation-based training by allowing clinicians to practice their skills before performing real procedures. The design of such simulators is usually focused on the primary operative tasks to be taught, but little attention is paid to secondary tasks that the user needs to perform, such as changing his/her point of view when manipulating the surgical instruments. More particularly, it is not clear how to design appropriate interaction techniques for those tasks, and how the fidelity of these interactions can impact the user's performance on such systems. In this paper, we compare two viewpoint changing techniques having two different levels of interaction fidelity during needle insertion in a semi-immersive VR (SIVR) biopsy trainer. These techniques were designed based on observing clinicians performing actual biopsy procedures. The first technique is based on tracking the user's head position (high interaction fidelity), while the second technique is touch-based with the user utilizing his/her non-dominant hand fingers to manipulate the point of view on a touch screen (moderate interaction fidelity). A user study was carried out to investigate the impact of the interaction fidelity of the viewpoint changing task (secondary task) on the user's performance during the needle insertion task (main task).

“…Moreover, studies have shown that retention, concentration, and enthusiasm have been positively linked to active learning models particularly for VR training simulations. [3][4][5] To address the need for skilled technicians in advanced packaging and assembly techniques, a desktop VR simulation was developed to train students in operating a high speed, high accuracy pick and place die bonder, which was deployed during the 2022 and 2023 integrated photonics bootcamp. The VR simulation allows the learner to pick and place die onto substrates multiple times in a safe virtual environment at minimal cost while allowing them to gain familiarity with tools and equipment used in the process.…”

MassTech Collaborative has helped to make the Commonwealth of Massachusetts a beacon for advanced manufacturing. In partnership with the AIM Photonics manufacturing institute, MassTech has launched five Laboratories for Education and Application Prototypes (LEAPs) within academic institutions and/or companies spread across Massachusetts, to develop a skilled workforce in integrated photonics. Hands-on and in-person workshops, bootcamps and laboratory courses are offered at these LEAPs to learners from academia, industry, and the government. The MA LEAP network stands as an excellent self-sustaining model for hands-on STEM education and workforce training for the rest of the country.
