Welcome to the Home of BioEra!

What is BioEra?

BioEra is a visual designer useful for analyzing signals in real time. It can be used with any device that has an ability to stream data to computer.

What is it for?

BioEra provides environment and tools to create various types of processing tasks. It can be used for research, games, self exploration, entrainment, sound processing and many others. Each task is contained in a design. To create a design no programming skill is required, only understanding of the process and its requirements.

How it works?

BioEra is used to create a design visually. A design represents data flow from input (e.g. biofeedback device) to output (e.g. visual or sound feedback). The flow can be customized with hundreds built-in objects (elements). For example an amplitude of alpha brainwaves can be filtered from input EEG signal, it can then trigger a MIDI, video or a computer task at a certain threshold level.

Is BioEra for biofeedback only?

Biofeedback is primary purpose of BioEra, but it can be used also for other types of digital signal processing (DSP).

On which OS BioEra can run?

Windows XP, Linux, Mac OS X , PocketPC PDA and linux PDA.

--> Currently supported are: Windows XP, Vista and Windows 7. Development versions were confirmed to work on Linux, Mac OS X, PocketPC PDA, linux PDA which may be supported in the future.

What can be done with BioEra?

BioEra offers high performance, flexibility and unique features not found in any other software. It can process dozens of channels simultaneously in real time (QEEG), many types of biofeedback devices can be connected together all in the same time. A single design with 1000 elements and 3D rendering can use as little as 2% of a processor (tested on Pentium 4, 2.4GHz).

Some features (full list is available in manual):

  • Streams (like bio-signals or sounds),
  • Logical states (ON,OFF)
  • Vectors (arrays of data)
  • Matrices
  • Images
  • Text
• Graphic visualisation
  • Oscilloscope, Polygraph
  • Vector display (FFT), 2D or 3D in real time
  • Topograph - can display 22 channels in real time!
  • Video and audio
  • Text messages
  • Images
  • Numeric values
  • Box display, bar display, progress bar
• Perform wide range of mathematic transforms
  • FFT (on real or complex values)
  • Digital filtering (with Butterworth, Bessel and Chebyshev filters).
  • Arithmetic operations (e.g. add, subtract, multiply, modulo etc).
  • Mixing, concatenations, windowing, multiplexing, range mapping, thresholding
  • Cross correlation (on scalar or vector streams)
