Building an effective ontology for assistive technology

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


The aim of this paper was to develop and validate an ontology for one class of assistive technology (AT), namely physically controllable pointing devices, using the Delphi method. Six occupational therapists with AT expertise identified important items and categories to the pointing device prescription through a three-round, structured process consisting of responses to a series of questionnaires. The intraclass correlation coefficient (ICC) was used to assess the interrater reliability of items included in categories related to the pointing devices and to the user profile. During the first round, the ICC ranged from 0.19 to 0.97; this improved to ICCs ranging from 0.72 to 1.0 during the second round. A full consensus was reached by the experts during the final round which included 218 items, divided into five categories, for the pointing device list, and 168 items, divided into six categories, for the user profile list. This ontology is expected to help achieve a more systematic regulation of the AT field, leading to greater standardization and increased knowledge sharing.
