Introduction ¶

EventIDE is a visual programming platform for designing and running psychological experiments. The platform is the most feature-rich and combines a friendly visual designer with professional programming tools. You can check the complete feature list of EventIDE here and also watch live demos of some features on our youtube channel

Main features ¶

EventIDE belongs to the so-called stimulus presentation software tools. When compared to its competitors, EventIDE excels greatly in complete visualization of design process, experiment scenario and flow logic. Creating an experiment in EventIDE is somewhat similar to creating a slide presentation, except that a user has much more control on flow logic, interaction with hardware and, importantly, runtime adjustments of the designed content.

The core feature of EventIDE is a revolutionary easy programming paradigm. The paradigm allows virtually any programming language can be used for scripting in experiments. There are no dedicated routines and libraries related to the experiment design and, correspondingly, no necessity to learn them. Writing code is required only for the customization of the experiment logic, which usually takes just a few lines. For example, implementation of the classic Stroop task requires only 14 lines of code in EventIDE. Yet, when it is needed, the power of professional programming languages is fully available in EventIDE.

The modular architecture of EventIDE allows easy integration of user extensions directly to the program core.

Background ¶

EventIDE is built over the Microsoft .NET. The platform is fastest and most feature-rich in its class and incorporates a friendly GUI designer with a family of professional languages (C#, C++, Basic, Python) for user coding. EventIDE automatically handles low-level logic, such as hardware and precise timing, and provides detailed visualization of design process. User coding is required only to customize the experiment scenario flow. Coding in EventIDE is extremely simple and light-weighted. Unlike other programs, there are no dedicated library calls that need to be learnt. Only standard programming statements are used, such as variable assignments, conditions and loops. A typical experiment can be coded just in dozen of lines.

Architecture ¶

Core ¶

The application core handles experimental logic whereas the switchable extensions (AddIns) give access to selected functionality, such as support for experimental hardware, time audit, data collection, research methods, etc.

Extensions ¶

• Psycho-physical methods extension. This extension provide the most common psycho-physical mathematical and statistical methods used in design and analysis of behavioural experiments.
• Eye-tracking extensions. These extensions are intended for communication between EventIDE software and various models of eye-trackers (Tobii, EyeLink, SMI, Arington).
• Body-tracking extension. This extension provides 3D real time body- and head-tracking with Kinect.
• Signal processing extension. This extension provides communication between EventIDE software and various EEG hardware. This extension brings a number of real-time signal processing algorithms adapted to an arbitrary signal analysis at the background of experiments.
• Neurofeedback extension. This extension provides communication between EventIDE software and EEG hardware. This extension predicts the phase of certain rhythms of the brain in real-time and present stimuli at the certain phase of the EEG signal, for example, at the moment of maximal activity of certain zone of the cortex.
• Data acquisition extension. This extension provides support for the data acquisition computer cards (National Instruments and Measurement Computing).
• MIDI extension. This extension is capable of reading the input of various MIDI devices connected to a PC. MIDI is a commonly-accepted protocol for communication with digital musical instruments, like MIDI piano keyboards. The MIDI Input element can record a instrumental music played in real-time as a sequence of notes.
  

User Extensions ¶

A modular architecture of the platform allows in-core integration of user extensions for experimental methods and custom hardware.
