Computer Assisted Personal Interviewing (CAPI) is the process of using  portable computers and data collection software to interview subjects.  Quality CAPI software, such as Survey System will reduce errors and the time required to collect data.

Computer Assisted Self-Interview (CASI) is the process of having subjects fill out surveys about themselves on a computer.

Survey System has been used on Tablet PCs in clinical environments where patients filled out surveys about themselves. 

Patients who reported not being comfortable with computers also reported that filling out surveys with Survey System was easier than the paper portion of the survey.

Survey System also provides locking mechanisms to stop the subject from accessing other data when the tablet is in their possession.

A quality CAPI solution must provide an efficient way to create questionnaires and collect data in those questionnaires.  It should not be intrusive on the interviewing process (i.e. a lap top being placed between the interviewer and interviewee).  It should also be as intuitive if not more intuitive than collecting information on paper.

Survey System's WYSIWYG design interface is comparable in both time and complexity to creating a survey with a word processor.  The tight integration with a Tablet PC makes the interviewing process similar to two people sitting across from each other where one is holding a clipboard and recording information.

Survey System goes beyond the simulating paper surveys paradigm in several ways.

While other CAPI solutions "RUN ON" a Tablet PC as all windows applications do, Survey System was built from the start with the Tablet PC in mind.  To understand this difference, download and compare using Survey System on a Tablet and another CAPI product.
