Currently, the ESAT knowledge base has been completed and the system will be launched for a testing phase at the project’s initiator ([http://www.vo-fab.at/]). The knowledge base has been implemented by mainly one knowledge engineer using KnowWE. For knowledge representation production rules are used. In total the ESAT knowledge base currently contains 654 rules distributed on 74 wiki articles. Also in this single-user context the possibility of free structuring allows for reasonable and clear distribution of the knowledge. The terminology is defined on different wiki articles dealing with vision, hearing, motoric and haptic abilities and general skills (e.g., braille) respectively. The about 50 different types of input and output devices (e.g., various kinds of keyboards, sensors, displays) are each described in distinct wiki articles also containing the rules relevant for the derivation of the particular device. Five heuristics have been established within a theoretical study, describing solutions for major categories of handicaps. These are implemented on distinct wiki articles forming the core of the derivation knowledge.
Currently, the ESAT knowledge base has been completed and the system will be launched for a testing phase at the project’s initiator ([http://www.vo-fab.at/]). The knowledge base has been implemented by mainly one knowledge engineer using KnowWE. For knowledge representation production rules are used. In total the ESAT knowledge base currently contains 702 rules and 80 wiki articles. There are 64 input parameters to gather the knowledge for each case. Also in this single-user context the possibility of free structuring allows for reasonable and clear distribution of the knowledge. The terminology is defined on different wiki articles dealing with vision, hearing, motoric and haptic abilities and general skills (e.g., braille) respectively. The about 95 different input and output devices, technologies and support software (e.g., various kinds of keyboards, sensors, displays) are grouped together and described in distinct wiki articles also containing the rules relevant for the derivation of the particular device.
The derivation of the results is based on heuristics and requirements, which are defined for assisting device. Therefore, the rules for the specific requirements in most cases are defined directly on the page that defines the assisting device.
Additionally, five comprehensive heuristics are defined on distinct wiki pages, as their derivations rules establish groups of multiple assisting devices that are employed together as combined solution.
Hence, attaching this knowledge to the device definition pages would be render inconvenient.

The testing framework for continuous integration discussed in Section 3.3 is extensively used to guarantee the save development process by uncovering undesired side-effects of modifications including at least one sequential test case for each device and heuristic. More details about the project are given by Kreutzer.
