SOCR Project - SOCR Interactive Optical Illusions Project
Project Goals
This project aims to design, implement and promote a set of diverse optical illusions using motion, color, shape, appearance, visual and perceptional cues, etc. The applets mush be lightweight, allow user interaction, convey interesting/unexpected visual illusions, and provide appropriate explanations for all of these visual perceptions. One example is the Pacman's illusion (right). Additional examples of such visuals are included below.
Adelson-Checker-Shadow
The Adelson-Checker-Shadow illusion is very interesting. The color/shade of square A is exactly the same gray shade of square B. You can see the evidence by clicking on the Show button to the right. Even after seeing the proof, your eyes may still keep deceiving you.
Reveal Illusion
Tables Illusion
Are these tabletops the same size?
Reveal Illusion
Alternative Illusion Projects
There are a number of alternative mind-illusion projects similar to the optical illusions that can be initiated.
Audio Illusions
One can use audio stimuli to convey an illusion or to capture data about sound/tone perception. Then one can investigate phenotypic effects (e.g., gender and age) on the brain processing/perception of audio signals. See Sound-Cloud.
- Examples of audio illusions are listed here. These include sound samples here are the scale illusion in which you'll hear different melodies in each ear depending on whether you're left or right-handed and the virtual barbershop, which essentially demonstrates how you hear and how the brain processes sound and its relation in space.
- A tone deafness GUI provides an interesting approach to surveying users' audio processing capabilities.
- There are 2 different types of hearing loss, sensorineural (brain) and conductive (ear).
- JavaScript resources for the Audio Illusions Projects
- Generate notes, intervals, chords, and scales
- Audio Player (takes *.ogg *.oga formats)
- JavaScript converter for different media formats.
Optical Illusion Survey
Please complete this anonymous SOCR Optical Illusions Survey and the Summary Results of the survey.
Audio and Sound Illusion Survey
Please complete this anonymous SOCR Audio/Sound Illusions Survey and the Summary Results of the survey.
