Support Reactions in Three Dimensions01:27

Support Reactions in Three Dimensions

Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system from translating and rotating, ensuring the design can withstand external forces and perform its intended function efficiently and safely. Some of the supports providing support reactions in three dimensions are discussed below:
Ball and Socket Joint is one of the supports allowing free rotation about any axis. This freedom of rotation is...
Virtual Work for a System of Connected Rigid Bodies01:06

Virtual Work for a System of Connected Rigid Bodies

Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.

Modeling and Similitude01:12

Modeling and Similitude

Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...

Area of Science:

  • Virtual Reality (VR) and Affective Computing
  • Neuroscience and Psychology
  • Human-Computer Interaction (HCI)

Background:

  • Virtual Reality (VR) is increasingly used for psychological research, but cost-effective methods for validating affective stimuli are needed.
  • Affect induction in VR requires carefully designed and validated virtual environments (VEs) and events.
  • Remote validation of VR stimuli using online surveys is an underexplored but potentially efficient approach.

Purpose of the Study:

  • To develop and validate a 3D Affective Virtual environments and Event Library (AVEL) for affect induction in VR.
  • To assess the effectiveness of an online survey method for validating VR-based affective stimuli.
  • To evaluate the perceived valence, arousal, presence, and memory recall associated with different VEs and events.

Main Methods:

  • Development of three 3D virtual office-replica environments designed to elicit negative, neutral, and positive valence.
  • Inclusion of specific affect-inducing events and objects within each VE.
  • Validation using an online survey with 67 participants rating video/picture stimuli for valence, arousal, presence, and memory.
  • Administration of an alexithymia questionnaire.

Main Results:

  • User ratings successfully validated the intended valence and arousal levels for each VE and event/object.
  • High perceived presence levels were reported for the VEs.
  • The online survey method effectively validated the VR stimuli for affective and cognitive research.
  • Participant memory recall for events/objects was also assessed.

Conclusions:

  • The developed 3D Affective Virtual environments and Event Library (AVEL) is a validated tool for VR-based affect induction.
  • Online survey validation is a cost-effective and scientifically sound practice for VR stimuli in affective and cognitive neuroscience.
  • This methodology supports future VR research in psychology and related fields.
