It is used primarily by architects, but has tools for surveyors and mechanical, civil and construction engineers. It was initially designed as an electronic drawing board, using concepts and tools clearly related to a physical board. Caddie requires a USB dongle. or software activation. Without the dongle or activation, the program can be used as a viewer and plot station for any DWG drawings, but it can't save drawings after the 14-day evaluation has expired.

Computer-assisted personal interviewing may be because wearing headphones increases the insulation of the respondent for external stimuli, and also may be explained by the fact that the recorded human voice in the audio component evokes a more personalized interaction between the respondent and the instrument. Computer-assisted interviewing methods such as CAPI, CATI, or CASI, have been the focus of systematic reviews on the effects of computer-assisted interviewing on data quality. Those reviews indicate that computer-assisted methods are accepted by both interviewers and respondents, and these methods tend to improve data quality. In a study that compared Audio-CASI with paper SAQs and Video-CASI, researchers
