There are two types of magic pointing techniques, which are:
- LIBERAL APPROACH
The liberal MAGIC pointing technique cursor is placed in the vicinity of a target that the user fixates on.
This technique allows user to take control of the cursor by hand near the target or ignore it and search for the next target. In addition, this magic pointing techniques is different from traditional eye gaze control, where the user uses his eye to point at targets either without a cursor or with a cursor.
- CONSERVATISM APPROACH
The conservative MAGIC pointing technique with "intelligent offset"
The conservative Magic pointing techniques with ‘intelligent offset’ ‘Intelligent offset’ meaning that the cursor position is offset to the intersection of the manual actuation vector and the boundary the gaze area. This means that, the cursor is likely to appear in motion towards the target, regardless of how the user actually actuated the manual input device.
