dob pro Visual Perception Training

1. General

dob pro is an educational software suited for the promotion of basic visual and visuomotor skills. It is especially designed for the needs of visually impaired persons. The high extent of individualisation further allows its use in various fields of the curative as well as the special education, in rehabilitation, and as an assisting and observatory instrument in early education.

dob pro offers a broad range of exercises, covering easy stimulations, generally basic tasks as well as the training of cognitive skills

Photosensitive Warning

A very small percentage of individuals may experience epileptic seizures when exposed to certain light patterns or flashing lights. Exposure to certain patterns or backgrounds on a computer screen may induce an epileptic seizure in these individuals. Certain conditions may induce previously undetected epileptic symptoms even in persons who have no history of prior seizures or epilepsy.

i.1. Concept and Structure

dob pro offers more than 2500 exercises for the training of the most important visual skills allocated into six modules. They can be used as required in a wide variety of situations.

The integrated tools enable individual support planning:

• Arrange exercises in a lesson
• Save and organize frequently used exercises to favorites
• Develop your own, individually adapted exercises with the integrated editor
• Exchange exercises with other professionals, using the export/import function

In general, those learning with dob should be accompanied by a professional who can explain the exercises and give support where needed.

2. Using dob pro

12. Evaluation exercise

While you are working, dob pro captures any typing and clicks on your computer screen, whether these are right or wrong and measures the time span between any action on the computer screen.

A simple click on the       button in the main menu will open evaluation settings.

Note
Exercises are not evaluated in module stimula.

12.1. Evaluation settings

Exercise data are stored. Data are not stored. Access to the stored evaluations

Note

dob can only store a limited number of exercices. The number depends on the complexity of the data. Take screenshots of important evaluations to store them permanently.

12.3. Evaluation examples

Depending on module or exercise category, evaluation shows different values and presents the activities on a single or on several screens.

12.3.1. Evaluation 1:
Modul spot – Gaze Switching horizontal

Task / Opacity / Time between beginning task and click / Thumbnail object

Click outside any object  error time
Task 2:
2 Clicks on the left side underneath the object

Task 12:
2 Clicks on the left side above the object

Observations and interpretations
• Needs much more time for objects at the right edge of the screen.
• At the right side many clicks outside the objects.
• Restrictions of the visual field?

The activities on the screen are displayed on one screen for following exercise categories:
– Fixation spot
– Gaze Switching spot
– Visual Field spot, spotPlus

12.3.2. Evaluation 2:
Modul spotPlus – Search and find shape

Task / Time until click on the correct object / Object

Wrong  Time until click on the wrong object / Object
Task 3, 5, 8:
Click on the wrong object

Outside  Time until click outside the object / Object
Task 7:
Klickt 2x clicks beside object

Skipped task (SPACE)
Task 9 and 10:
breaking off

Observations and interpretations
• Confuses shapes (filled square with frame)
• Nos ystematic search
• Overwhelmed with increasing number of objects
• Practice search strategies

Activities are displayed on 6 screens.
Exercises with more than 6 tasks share clicks of several tasks (e.g. task 1 and 2) on one screen.

12.3.3. Evaluation 3:
Modul zoom – Contrast

Task / Opacity: Change from 0 to 100% / Opacity when clicking /
Time until click / Object

e.g. Task 3:

Task 2 and 9:
One click outside object

Observations and interpretations
• Enjoys working with emoticons
• Can interpret facial expressions
• Faster detection of objects on the left side
• Restrictions of the visual field?

Activities are displayed on 6 screens.
Exercises with more than 6 tasks share clicks of several tasks (e.g. task 5 and 6) on one screen.

12.3.4. Evaluation 4:
Modul track – Collecting goals

Task / Time until reaching the target Task 1:
No collision

Time until collision
Task 2:
Collided after 5.8 and 9.4 seconds on vertically mounted track.
Reached target at 15.3 seconds.

Observations and interpretations
• Knows the collected objects
• Increasing muscle spasms

That object will stay visible and remain at a defined location on the screen for the duration of the entire exercise. For the requested objects there is circle or line to chose from. Those special settings will only appear in exercises of category Eccentric Fixation.

Example Circle:

Move the slider to set the distance from the requested objects to the fixed center of the circle.

Circle: The requested objects are arranged in a circle around the foreign object.

Example Line:

Move the slider to set the distance from the requested to the fixed object.

The object will be displayed in the center of the selected field.
If Center (exactly)  is selected for both the requested and the fixed object, the distance is defined and cannot be specified additionally.

Line: A requested object appears alternately from task to task at the defined locations.
