emoTouch 

emoTouch is a scientific research tool that was designed primarily for reasearch on musical emotions but can also be used for a lot of other topics.

In an emoTouch session the participant can continuously mark his reactions to music or video played by the device or a live performance in one or two dimensions. As an example emoTouch can be applied for recording emotional self-report using the two-dimensional emotion space with its dimensions valence (negative – positive) and arousal (active – passive). For the first time, emoTouch provides a tool where the participant may intuitively touch the emotion space itself.

A lot of implemented features and options enable emoTouch to work as a suitable tool for numerous research topics:

• user feedback options: a smiley or custom image to mark the position and a „worm“, visualizing the just performed movement
• mark special events (e.g. musical chills) with a special gesture
• music and video selection from the device's media library
• silent mode for rating live performances
• configurable coordinate system with user-defined labels
• limit the dimension to x- or y-axis only. In this mode emoTouch may work as a one-dimensional slider.
• free choice of background images to adjust the design and scaling to your question, also as a (partial) overlay on the video
• sampling frequencies up to 30 samples per second
• replay mode for displaying recorded data in realtime, also several sessions/participants at the same time and optional visualization of mean and standard deviation
• data export to a configurable text file that can be used with all standard statistic programs

emoTouch is only available in English, but provides options to change all the text that participants in a study will see, so any language can be used. emoTouch is a developement of the chair of systematic musicology of the University of Osnabrück (Prof. Dr. Christoph Louven, Carolin Scholle).

What's New in Version 3.0

video mode: A video from the iPad’s media library can be played behind the coordinate system.

•The video can be overlaid with an image to show a custom rating scale.

•beta-function: replay mode with video

•show a webpage at the end of each session, e. g. for an additional questionnaire or a “thank you” window

•offset for one-dimensional data recording so the axis can be at user-defined height

•username is saved with an additional time stamp

emoTouch is running on iOS 7 or higher on Apple iPad and iPad mini, iOS 7, available for free on the AppStore.
