Compared with the traditional method of investigation, CAPI showing the following advantages:

- "Question" way to play sound files available

- "Question" way to play video files available

- "Question" Available photos, pictures, concept cards display

- "Answer" recordable recorded

- Supports 3D, FLASH, JAVA

- Support for virtual shopping scene

- Support copywriting hot hot pictures, audio and video hot choice

- Automatic error correction logic, intelligent jump control, to avoid human error

- Randomly display, reducing random error

- Record access procedures (such as time, with time, interval and order, etc.), which restricts the interviewer's cheating

- Save photo prints, concept card printing, data entry time and costs, the project's focus on speed, CAPI relatively traditional traditional access has a strong advantage

- Access to a strong positive impact on both interest and improve the acceptance of respondents’ access;

- Can access data statistics in any time period;

- Can perform complex correlation and parameter calculation: [single title frequency statistics [table title, three-dimensional form title statistics [cross statistics [synchronous drawing, popular graphics to choose from [statistics more at the same time, and the corresponding chart [data export can be directly used by SPSS, SAS statistical analysis.
