Source: Alexander S Rattner and Sanjay Adhikari; Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA Objects, vehicles, and organisms immersed in fluid mediums experience forces from the surrounding fluid in the form of buoyancy- a vertical upward force due to fluid weight, drag- a resistive force opposite the direction of motion, and lift- a force perpendicular to the direction of motion. Prediction and characterization of these forces is...

Classical fear conditioning paradigm was adapted for human participants in a fully immersive virtual reality setting. Using a discrimination paradigm, conditioned fear, cue and context memory retention, and extinction was measured with skin conductance response to dynamic virtual snakes and spiders (the conditioned stimuli) in two distinct virtual contexts.

Cryo-electron tomography (cryo-ET) enables 3D visualization of cellular ultrastructure at nanometer resolution, but manual segmentation remains time-consuming and complex. We present a novel workflow that integrates advanced virtual reality software for segmenting cryo-ET tomograms, showcasing its effectiveness through the segmentation of mitochondria in mammalian cells.

FAQs
Immersive experimentation links interactive environments with simulation models, haptic interfaces, and real-time sensor feedback. A user can manipulate a design or operating condition, while the system presents corresponding responses for evaluation. This connection allows engineers to study both technical behavior and human-system interaction in the same trial, making design weaknesses easier to identify before committing to a full-scale prototype.
Repeatable trials let engineers examine the effects of changed variables under comparable conditions. Instead of treating each test as an isolated event, teams can iterate through alternative designs or operating conditions and observe how system responses differ. This supports more informed engineering decisions because findings can be revisited, refined, and compared without immediately rebuilding a physical system.
Immersive experimentation provides a way to evaluate designs and interactions before a full-scale prototype is built or exposed to significant risk. Digital or physical environments can support early trials, while simulation and feedback technologies show how the proposed system responds. Engineers can therefore reveal weaknesses, refine concepts, and potentially reduce development costs before committing to more extensive construction or testing.
A typical workflow begins by placing a design, system, or human interaction in an interactive digital or physical environment. Engineers then allow users to manipulate relevant conditions, monitor system responses through simulation or sensor feedback, and evaluate the results. Repeated trials support design iteration, helping teams refine the concept and decide whether it is ready for more substantial prototyping or implementation.
The approach can combine virtual reality or augmented reality with simulation models, haptic interfaces, and real-time sensor feedback. Virtual or augmented environments present the design context, simulation models represent system behavior, haptic interfaces support physical interaction, and sensors report responses as trials occur. Selecting and combining these technologies helps engineers examine both system performance and the user's interaction with it.
Engineers can apply it to product development, robotics, manufacturing, infrastructure, and safety training. In these settings, trials can reveal design weaknesses and provide evidence about human-system performance before a complete physical system is available. The same approach also supports rapid iteration and safer evaluation, making it useful when teams need to compare alternatives or practice interactions under realistic conditions.
