dob plus Visual Perception Training

1. General

dob plus 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 plus 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 of dob pro 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 plus

2.1. Requirements

2.1.1. General

Through the use of different entry options (touchscreen, switching device, mouse or keypad) the programm takes into account the special conditions of multiply retarded people. In most of dob's exercises, the user's options are limited to a number of two: confirm and continue, commanded by the keys/gestures SPACE       and ENTER      . Those two commands can also be defined on a switching device, allowing a most individual approach within each exercise. In general, those learning with dob should be accompanied by a professional who can explain the exercises and give support where needed.
  Keyboard shortcuts and touchscreen gestures

  overview of all exercises sorted by category on www.dob.li

4.4.1 Name of Predefined Exercises

The titel of an exercise generally contains a two-part name, a code and is possibly followed by a specification. The first part of the name describes the type of the exercise (e.g. Gaze Switching), the second additional word (e.g. vertical) further limits the type of exercise. The code gives reference to the design of the visual environment.

  Exercise Catgories and Primary Skill

Example: Gaze Switching vertical L_col_2, animated

Task	Object size		Colors, contrasts		Number	Addition
Text	XXL	maximum size	pos	Dark object on a light background	Nr.	*

	L	large	col	Colored object on a colored or patterned background
	M	medium
	S	small
	XS	very small
	XXS	minimum size
	R	range, sequence

The supplements after the code indicate further special features.

10. Evaluation exercise

While you are working, dob plus 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.

10.1. 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.

10.2. General options

Personal notes Date and time Total Duration:: Time per complete exercise Sum Tasks: Duration minus the time for confirmations and rewards = pure exercise time Task list Average time per task

10.3. Evaluation examples

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

10.3.1. 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

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