Summary
This study introduces a method to detect speaking intentions in virtual reality (VR) group discussions using sensor data. This technique enhances non-verbal communication for more engaging remote interactions.
Area of Science:
- Human-Computer Interaction
- Virtual Reality
- Communication Technologies
Background:
- Virtual reality (VR) facilitates remote communication via 3D avatars but struggles with non-verbal cues in group discussions.
- Limitations in non-verbal communication hinder engaging group interactions in distributed virtual environments.
Purpose of the Study:
- To develop and evaluate a technique for detecting speaking intentions in VR group discussions.
- To improve the quality of non-verbal communication and engagement in virtual collaborative settings.
Main Methods:
- Developed a prototype VR group discussion application with sensor data logging from headsets and hand-controllers.
- Conducted experiments with 24 participants to collect quantitative and qualitative data on speaking intentions.
- Analyzed temporal patterns of speaking intentions and participant experiences.
Main Results:
- Identified distinct temporal patterns associated with different speaking intentions.
- Proposed a sensor-based mechanism for detecting speaking intentions tailored to these temporal patterns.
- Verified the feasibility of the proposed detection mechanism in VR group discussion scenarios.
Conclusions:
- Sensor data from VR hardware can effectively detect speaking intentions.
- A sampling strategy considering temporal patterns enhances the accuracy of intention detection.
- This approach has the potential to significantly improve virtual group discussion engagement.

01:01Group Polarization
34.3K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

01:10Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

01:34Groupthink
44.3K
When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...
