|February 23, 2019
Summary
This study introduces a novel smart glasses device for pattern-reversal visual evoked potential (PR-VEP) tests. The portable, low-cost system shows promising results comparable to commercial devices.
Area of Science:
- Ophthalmology
- Neuroscience
- Biomedical Engineering
Background:
- Clinical electrophysiology relies on accurate visual evoked potential (VEP) testing.
- Traditional VEP equipment can be expensive and cumbersome.
- Developing portable and accessible diagnostic tools is crucial for widespread clinical application.
Purpose of the Study:
- To present an integrated smart glasses device for pattern-reversal visual evoked potential (PR-VEP) testing.
- To evaluate the efficacy and reproducibility of this novel approach compared to commercial systems.
Main Methods:
- Smart glasses were utilized to generate dynamic checkerboard patterns and fixation points via an Android application.
- Electroencephalographic (EEG) signals were wirelessly transmitted from scalp amplifiers to a PC.
- A real-time MATLAB algorithm processed EEG data to extract PR-VEP signals.
Main Results:
- The smart glasses system successfully generated PR-VEPs with typical triphasic waveforms.
- Results demonstrated moderate agreement with a commercial PR-VEP recorder.
- The device showed potential for future improvements and refinement.
Conclusions:
- The developed smart glasses device offers a viable portable and low-cost solution for PR-VEP clinical testing.
- This technology has the potential to increase accessibility to VEP diagnostics.
- Further refinement may enhance the performance and clinical utility of the system.

The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical...

01:06Fixed Action Patterns
17.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

5.8K
The thermodynamic processes can be classified into reversible and irreversible processes. The processes that can be restored to their initial state are called reversible processes. It is only possible if the process is in quasi-static equilibrium, i.e., it takes place in infinitesimally small steps, and the system remains at equilibrium However, these are ideal processes and do not occur naturally. An ideal system undergoing a reversible process is always in thermodynamic equilibrium within...

01:14Diode: Reverse bias
1.9K
A diode is reverse-biased when the positive terminal of an external voltage source is connected to the n-type material and the negative terminal to the p-type material. This configuration opposes the natural direction of current flow through the diode, effectively increasing the width of the depletion region and the barrier potential. The reverse bias condition produces a minimal leakage current, primarily due to minority charge carriers. This leakage becomes significant when the reverse...

00:52Potential Energy
42.7K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...
