Research Facilities

  • Eye-tracking
    The eye tracking facility includes a Tobii TX 300 Eye Tracker and comes with the Tobii Studio™ Eye Tracking Software. This is a state of the art- eye tracking facility that can be used flexibly for a variety of purposes including consumer behavior research, vision research and can collect data pertaining to saccades, correction saccades, fixation duration, pupil size and blinks.
    The facility also includes Tobii Toolbox, which supports data collection using MATLAB, thus minimizing the use of Tobii Studio for experimental design. Support is also available for E-Prime through extensions from Tobii.
  • Wireless Physiology-based Data Acquisition System
    Developed and manufactured by Biopac Systems Inc., Wireless Physiology-based Data Acquisition System facilitates the real time data acquisition of physiological signals. The system covers a wide range of physiology signals such as ECG, EMG, EDA and provides excellent signal quality with digital transmission with high resolution of 16 bit and at high speed up to 400kHz aggregate. The wireless, wearable physiological monitoring device, noninvasively records high quality data and is the perfect tool for applications that demand greater degrees of subject freedom and advanced experimental design. The system is compatible with the Virtual Reality-based programming platform from WorldViz.com.
  • Virtual Reality-based Devices and Programming Platform
    This is the software-programming platform, namely, Vizard from WorldViz Inc. Vizard is a high level graphics toolkit for the development of high-performance graphics applications, including Virtual Reality (VR), scientific visualization, games, and flight simulation. The VR platform provides controlled and replicable experimental setups and allows manipulation of the environment (and avatars) that would be impossible or prohibitively expensive in the real world. Use of the VR Toolkit along with Biopac data acquisition and analysis system to synchronize events from the virtual world with the physiological data, allows accurate and automated data analysis and adds a new dimension to the research. The Centre has also acquired a 3D virtual reality display (Oculus Rift).
  • Virtual Reality Motion Capture System
    This custom-developed system uses electromagnetic sensors (Ascension trakStar, Northern Digital) to record arm movements made in the horizontal plane. It is interfaced with the Motion Monitor (Innsport, Chicago, IL) as well as autonomously developed software to provide a virtual reality environment, which enables recording of arm motion data under a variety of different task conditions. This system can be integrated with a range of external devices including EMG, EEG and TMS equipment, which allows quantification as well as disruption of neural activity during arm motor tasks.
  • 128 Channel EEG
    The high density EEG facility is a complete system with 128 channel EEG sensors, amplifier, and software. The Geodesic Sensor Net (GSN) provides a simple method to apply dense arrays of sensors quickly and easily in just a few minutes. The GSN gently holds each silver/silver chloride electrode sensor in place without the need for excessive head measurements or glues. And no scalp abrasion is necessary to get high-quality EEG data. Use with a simple saline solution for shorter recordings, or an inexpensive paste or gel for long-term recording. The result is a comfortable and low stress experience for your participants — even infants, children, or populations with behavioral challenges easily accept the GSN. The Net Amps 400 ampifiers can provide the low noise and high sensitivity required for acquiring high-quality EEG data. The Net Station software provides full acquisition, review, and analysis functions. GeoSource is a set of tools to model the neural sources of the brain’s electrical fields measured with the electroencephalogram (EEG) at the head surface.
  • Emotiv EPOC 16 Channel wireless EEG system – Research Edition
    Emotiv EPOC / EPOC+ features 14 EEG channels plus 2 references offering optimal positioning for accurate spatial resolution. Channel names based on the international 10-20 electrode location system are: AF3, F7, F3, FC5, T7, P7, O1, O2, P8, T8, FC6, F4, F8, AF4, with CMS/DRL references in the P3/P4 locations. Emotiv EPOC / EPOC+ uses sequential sampling method, single ADC, at a rate of 128 SPS or 256 SPS* (2048 Hz internal). Emotiv EPOC / EPOC+ operates at a resolution of 14 bits or 16* bit per channel with frequency response between 0.16 – 43 Hz.
  • Motion Capture System
    Ascension trakStar consists of 6 electromagnetic sensors and an electromagnetic transmitter. It records the three dimensional position of each sensors. It also records the elevation, roll and azimuth. These sensors can be attached on the fingers, elbow or shoulder etc. These sensors are very useful to record the motion of muscle joints up to 240 Hz.
  • Digitising tablet
    GTCO CalComp digitising tablet record the end point movement of hand. It has functional area of 36X24 cm. It records the movement of stylus on the surface of the tablet. It can record the movement of stylus at the rate of 60 Hz.
  • Behavioral cubicles
    Currently, there are three behavioural cubicles housing computers that support behavioural data collection. The cubicles are sound attenuated dark rooms with adjustable lighting. The PCs run MatLab with psychophysics toolbox and is currently used by postgraduate students and faculty members for research on decision-making, attention, agency etc. They also support E-Prime and other softwares such as Blitz3D. These labs are also used as private spaces for paper pencil tests and questionnaires that require an environment free of external interference.
