CASS-Query tool, based on Contextual Activity
Sampling System, is a Java-application for
collecting process- and context-sensitive data.
It allows you to gather data about various
learners and workers experiences, feelings and
thoughts in daily situations and settings where
they are evoked. It can be run in 3G mobile
phones and used freely without charge. If you
are a researcher or knowledge worker planning to
explore how the participants of your study
perceive and feel about their daily activities,
the CASS-Query may be suitable tool for you. It
can be tailored and elaborated for your
particular needs.

• CASS-Query enables you to create queries that the
  participants of your study receive to their
  mobile phones. Queries can contain various
  questions with different types of responses Open
  text, Likert scale, picture, video and audio
  recording. Responses are returned to server
  database once the participant indicates that it
  is completed.

• Data collected with CASS-Query can be transformed
  to SPSS software. You can use the data, e.g., for
  creating graphical illustrations about the
  responses received during the follow-ups.
  CASS-Query thus provides its users with a window
  into their daily experiences and helps them to
  expand their knowledge about how these
  experiences temporally coincide with various
  activities, settings and environments during the
  day.

• CASS-Admin, the management system of CASS
  queries, enables you to flexible adjust desired
  sampling procedures. It is thus up to you to
  decide whether to send the queries in fixed
  intervals or selected by the participants
  themselves on a certain moment. With CASS Admin
  you can download queries to server database,
  monitor the accumulation of data in real time as
  well as search and browse participant info and
  data.
