Question

What is the purpose of the tiny tubes in another technique of digital paper?

a.

To emit light and create pixels

b.

To absorb light and create pixels

c.

To hold reflective spheres for pixel manipulation

d.

To generate electrical signals for pixel control

Posted under Human Computer Interaction

Answer: (c).To hold reflective spheres for pixel manipulation Explanation:In this technique, tiny tubes in digital paper hold light-absorbing liquid and small reflective spheres. The movement of the spheres, either to the top surface or away from it, determines whether the pixel appears white or black. The spheres retain their position once the electronic signal is removed.
