Clients with moderate to severe limitationsafter homonymous visual field defects, neglect,disorders to visual exploration abilities and saccadicvisual movement. These occur, among other things,after cerebral infarctions in the supply area of thearteria cerebral media or posterior.

The clients look at a sun/moon (fixation point) on the horizon of a simply structured landscape. At irregular intervals, objects appear to the left or right of the fixation point, accompanied by a beep. Whenever the beep sounds, the client has to find the object with large gaze jumps and indicate by means of the arrow key, whether it is located to the left or right of the fixation point. At low difficulty levels, the horizon line helps with orientation. Optokinetic stimulation can be switched on as an additional help with neglect.

The training is recommended for clients with exploration problems after homonymous visual field impairments or visual neglect and can also be used as visual-spatial attention training. It is suitable for establishing a previously acquired exploration strategy in unstructured training material.

There are four different types of tasks. In the task type „Search for missing numbers“, numbers scattered on the screen should be searched in order and the missing numbers should be identified. Find Items requires finding and clicking certain items embedded in scenes. In the task type „Find and count objects“, the number of given objects must be determined. The „superimposed figures“ task is used to train detailed analysis. Simple figures are superimposed. The clients have to decide what the basic forms of the superimposed figure are.

For neurologically caused visual disorders, e.g. right or left sided quadrant anopsia and the resulting perception and processing disorders. Visual restoration training requires a high training frequency and duration. At best, daily training for at least 50 - 100 sessions is recommended.

The aim of the training is to stimulate the peripheral area between the intact and impaired visual field. To do this, the clients keep their eyes on the fixation point. The light stimulus first moves from the intact visual field to the affected one until the client can no longer perceive it (limit of perception). At this point, the light stimulation lingers until the light stimulus moves one line below or above the stimulation point again from the healthy area to the perceptual border in order to stimulate here. Determining the limits of perception as well as ensuring fixation in the middle of the screen are carried out by the client pressing a button.
