research on visual perception and visual attention fields

>Eye-tracking is a modern research method that allows to determine precisely the areas of the perceptual field (eg website, newspaper ads, or a movie) on which the person who sees them focuses attention. Sampling frequency is 1250 Hz and the measurement error does not exceed 0.01°. The results can be presented in the form of dynamic or static graphs (examples) or in numerical form, to be used for further statistical or mathematical analysis. Visual images can be displayed on LCD monitors (17 ", 20" and 23 ") Plasma Monitor (63") or the screen (3 m x 2.3 m) in front and rear projection in 2D and 3D standard.

research on Event Related Potentials, ERP

Event Related Potentials (ERP) measures brain's electrical activity by means of electroencephalogram. It is used for the diagnosis of brain activity during the display of different visual or auditory stimuli. ERP technique allows the precise registration of brain activity, using 128 channels, even during small changes in stimulation, eg, resulting from movie montage, rhythm, melody, sound/audio effects, etc. EEG apparatus provides samples of brain's electrical activity with frequency of 1000 Hz, and this means that it can identify unconscious brain's reaction to the images presented to the recipient, eg. during audio-visual transmission. The laboratory equipment enables exposure to visual stimuli on LCD monitors (17 ", 20" and 23"), Plasma Monitor (63") or the screen (3 m x 2.3 m) in front and rear projection in 2D and 3D standard. Sound stimuli can be presented in Dolby Surround 5.1.

research on Fixation Related Potentials, FRP

Fixation Related Potentials (FRP) technique combines the Event Related Potentials method (ERP) and the Eye-tracking method responsible for recording eye movements. This technique therefore allows the diagnosis of brain activity when a person briefly fixates the eyes (i.e. stops to look) on some elements of the visual scene. Both the visual fixation time and response time of the brain are incredibly short, so that all operations carried out by a tested subject during the experiment are outside his/her consciousness. This method allows the analysis of data gathered from each type of exposure to visual media, both static images (such as photos, graphics, drawings) and films (eg, feature films, advertising, animated movies). Stimuli may be presented on all kinds of above-mentioned monitors.

monitoring of human physiological activity

Biofeedback is a technique for monitoring human physiological activity in several areas. Compact design of the equipment enables a noninvasive and convenient testing and recording changes of physiological parameters such as peripheral body temperature, blood flow, blood pressure/heart rate (ECG), the parameters of breath, skin conductivity response, changes in muscle tension. Using a simple EEG sensor it is possible to estimate the level of attention of the tested subject. Software allows gathering data with frequency up to 2048 samples per second for each channel (sensor) as well as immediate presentation of the results or the raw statistics. It is also possible to create interactive applications using the readings of physiological reaction (eg, manipulate and control objects with the mind).

high-resolution movie and sound production

By applying the latest digital techniques in conjunction with professional equipment, we are able to produce any multimedia material. This can be a full-length material prepared for television, or a short podcast for the websites, an interactive academic lecture or an outdoor interview. Materials can be enhanced with graphical effects (2D or 3D), spatial sound and music effects. We also prepare visual materials for presentation in the stereoscopic format.
