"Tactile Images": feeling the relief of images
Have you ever dreamt of feeling the relief
Now, it's possible!
You can download
the following examples by clicking on the images below.
you prefer to watch a video?
The idea is to give the illusion of
perceiving the relief of an image when the user moves the mouse cursor
over the image.
How does it work?
The speed and movement of the cursor are artificially modified.
If the cursor "goes uphill", it gets slowed down. Conversely, when the cursor goes
down a slope, it is accelerated. If the cursor hits a "wall", its movement is stopped.
The algorithm developed uses the "grayscale levels" of the displayed image.
In short, if the cursor moves from a dark point (or pixel) to a clear point (or pixel),
it gets slowed down.
