Level 1: Blank Screen Engagement
Blank Screen Engagement activities allow learners to explore cause and effect – when they look something happens, when they look away it stops – this concept is fundamental to learning eyegaze and needs to be explored in some detail.
Level 2: Object Displacement
Object displacement activities introduce some of the methods of eyegaze such as dwell functions and basic targeting – here learners may begin to gain greater awareness as to how their gaze proximity activates a response from content in a certain area of the screen.
Level 3: Zoned Focusing
Zoned focusing – an ability to target specific areas of the screen is an important step in learning to control the mouse cursor, now we want learners to be able to begin to fix their gaze in order to achieve a greater level of control and accuracy. At this point we are developing skills necessary to achieve a successful calibration.
Level 4: Active Exploration
It is of primary importance that learners are motivated to engage with the screen, active exploration activities encourage learners to engage with the wider area of the screen and have fun using their eyes.
Level 5: Controlled Targeting
Controlled targeting activities can help learners achieve greater control, a higher degree of accuracy and a more detailed understanding of the dwell function.
