PC -Android integration for a ressonable low cost CAPI face-to-face Surveys
survey system
A cost-effective yet powerfull Windows CAPI survey software

RotatorSurvey is a complete suite of professional, user-friendly tools that allows you to create and manage surveys of all kinds and methods, including face-to-face CAPI surveys (Computer Aided Telephone Interview). RotatorSurvey is one of few application available on the market today for the Windows environment, since most of the software solutions for surveys are SAS-Internet based services. The main problem with these solutions is that in order to manage, collect and analyze data, you must have fully access to the Internet. Not so with Rotator, where most of the processes including questionnaire design, survey administration and data collection are all done in a offline fashion, with a low-cost stand alone Windows application on your desktop. Rotator provides user-friendly screens which operate efficiently with any version of Windows, from Windows 7 up to Windows 10. CAPI Offline survey modeling on Windows offers multiple advantages when compared to traditional SAS online survey systems. Especially in those areas where telephone and Internet services are poor or not fully available, which is the case of our users operating in Latin America and Africa.

Why a vertical solution for face-to-face CAPI interviews?

Sometimes, Wi-Fi or mobile data may not be available at the location where your CAPI survey need to be conducted. Therefore, cheap online survey services, such as SurveyMonkey or QuestionPro cannot be used for this vertical scenario, we need a specific CAPI tool for that. Rotator Survey’s CAPI software solution allows you to collect data in an offline mode. There is no need for online connection while your interviewers are in the field. Thus, when you reach office, or get a data signal, CAPI surveyors may send their data to the cloud where your survey data is being centralized and consolidated.

RotatorSurvey CAPI App was designed for common users, with a very easy and intuitive interface, interviewers do not need any special training to go out and start applying surveys in the field. Nevertheless our App also offers advanced features that allow agents to complement the interview with images, videos, sounds and many more features required in a complex CAPI survey scenario. Advanced features are also provided in our low-cost CAPI tool App, as getting the exact latitude - longitude coordinate point where the interview was conducted (geolocation) or for instance, the recording of the voice of the interviewee for large opinions which allows to save time and to make the interview even more appealing.

CAPI Survey systems, to go ONLINE or OFFLINE

With the advent of the Android operating system, multiple software developers have created cheap CAPI Apps for the Market Research Industry, some of them require a fully internet connection, to properly operate in the field, for data capture, validation, analysis, etc. In the past, CAPI systems, i.e. those where a face-to-face interview with a subjects were carried out, researchers had to collect the data using paper, or in the most automated scenario through hand held computers or laptops. Nowadays the same researcher can apply a CAPI survey in the field using his smartphone, either using Android, IPhone or Windows Phone operating system. With our cost-effective Windows-Android CAPI solution, the modeling of the survey can be done on a Windows PC, but its application can be done with a Android mobile offline device. Rotator Software offers an inexpensive Windows-Android integration, allowing to synchronize the surveyed data in the field with a centralized cloud repository in a bidirectional fashion. This integration not only allow you to execute your CAPI survey smoothly, but it also allow you to keep your project on-budget, save money, time and effort.

A new affordable OLAP approach for CAPI surveys

Rotator uses a logic brought from tradicional OLAP systems, but unlike them, it does not contain a pre-calculated data such as MOLAP systems, nor does perform transactional querying for data consolidation, as Hybrid OLAP or ROLAP systems. The latter strongly leveraged from relational database engines such as Oracle, SQL 7 or Postgress. Instead of that, each cell in a Rotator's hypercube contains a Boolean formula, which triggers its automatic calculation when shown in a chart or report of the user's GUI, i.e., as if it was an SQL statement; But without using this language and without using a relational database engine either. For example, you could analyze what drinkers of "Bud Light" who support "Donald Trump" think about the abortion, its Boolean formula could be (V8 = 1 AND V20 = 2 AND V40 = 20). This simplicity and computational elegance makes Rotator's query engine a powerful, friendly and economical system to cross-tab any variable from our opinion survey collected in the field.

A proprietary database engine specific for data analysis

The core component of RotatorSurvey is a hyper-dimensional database engine called "Rotator" which is a proprietary technology developed by our engineers, and uses a different approach to query complex survey data. Traditional RDBMS store data in flat tables through registries and fields, but in OLAP models you use dimensions, hierarchies, and cubes to store and query the data. Rotator hypercubes are transparent to the user, but offer a great power and versatility, for those who need to collect and analyze data from a CAPI survey at a reasonable price. After data is being collected from the field, it allows the user to create complex reports and charts just in just minutes. For instance, in a CAPI survey modeled with Rotator it is possible to know what "Bud-Ligh beer drinkers" think about a political issue, crossed by Age and Sex, without having to export the data to SPSS, Excel or to any other statistical package. After a data cube is obtained, you will be able to slice it, dice it or transpose it (rotate it) in order to obtain multiple views of the same information. To accomplish this task at a reduced cost, you need either to export your data to SPSS, or use a vertical moderate-priced software tool, or a free complex-statistical analysis software such as the statistical Computing software "R".
