(New) - The complete clarification of all functional perception processes when moving a pointer toward an icon on a computer screen
0. Einstein, the Stationary Icon, and the Digital Clock: The Visual Perception Observes Stationary Icons Moving in Time
1. COMPUTER TASKS - Prior to moving a pointer toward an icon we always first construct a perceptual image of a latent action trajectory shape out of the perspective of the pointer – The scientific evidence
2. The functional perception processes related to the movement of a pointer at a computer screen - The execution of any imaginable motoric action requires the compelling cooperation of an internal and an external focus
3. When clicking on an icon, the essence of the task is solely executed by the movements of the pointer within the primary focus; The pointer becomes constrained within an action trajectory shape which produces the tau-value
4. The tau-coupling process when clicking an icon shows that we absolutely do not need a motor plan; Executing an external action trajectory shape within the external (primary) focus dictates all internal sensorimotor perception processes within the internal (secondary) focus
5. Transitioning from random motor activity to the execution of intentional actions demands shifting the internal and external focus; The origin of two autonomous foci and how their roles have evolutionarily reversed in relation to moving a pointer to an icon
6. The explanation of the emergence of the cortical streams - We can only guide a pointer to an icon with a zigzag movement, yet the ingenious mediation by the cortical streams creates the delusion of a straight action trajectory shape
7. Within a computer task the cortical streams will have to mediate the egocentric zigzag movement of the pointer toward an icon
