Central Instrumentation Facilities
Indian Institute of Technology Gandhinagar research initiative was started in 2012 and has the state of the art instrumentation facility as compared to any of the international universities or institutes in the world. The instrumentation facility has currently housed six major sophisticated instrumentations in the areas of Engineering, Science and Archaeology.
Cognitive Science Laboratory
The Cognitive Science laboratory consists of facilities that enable basic and advanced level research in cognitive psychology, affective computing, cognitive neuroscience, behavioural economics, and experimental philosophy. The facility consists of a collection of laboratories equipped with behavioural data collection cubicles, an eye tracker, a wireless physiology-based data acquisition system, virtual reality-based programming platform and will be supplemented in the future with a 256-channel EEG system.
There are currently three behavioural cubicles housing personal computers that can support behavioural data collection. The cubicles are partially sound-proof dark rooms with adjustable lighting. The computers have Matlab installed on them along with the Psychophysics Toolbox. These facilities are used by postgraduate students and faculty members for research on decision making, attention, agency etc. They also support E-Prime and other software 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.
Intelligent Affective Computing and Biometric Lab
Intelligent Affective Computing and Biometric Laboratory opens up a platform for wide range of interdisciplinary research in fields of Electrical Engineering, Cognitive Science and Biomedical Engineering. The laboratory facilities include Virtual Reality-based Programming Platform, namely, Vizard from WorldViz Inc. Vizard is a high level graphics toolkit for the development of high-performance graphics applications, scientific visualization, and games. The VR platform provides controlled and replicable experimental setups and allows manipulation of the environment that would be difficult or prohibitively expensive in the real world. Additionally, we have Wireless Physiology-based Data Acquisition System from Biopac Systems Inc. which is compatible with the Virtual Reality-based programming platform mentioned above. The Wireless Physiology-based Data Acquisition System facilitates the real time data acquisition of physiological signals, such as, heart beat, muscle twitching, sweating, skin temperature, etc. 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. Presently, we are using this device for biomedical applications, e.g., physiology-sensitive adaptive intelligent stroke rehabilitation and cognitive science applications, e.g., affective Human Computer Interaction for children with autism. We also have the facility of interacting with the computing world with the Eye Tracker from Arrington Inc. This allows to track real-time data of gaze, blinking, pupil dilation, etc. of the user. The analysis of parameters e.g., blinking, pupil dilation, fixations, etc. is significant for a variety of researches in areas of Biomedical engineering and Human Computer Interaction. While working with the virtual world human experience can be augmented by using Haptic Device. At our research lab we have the Haptic Device from SensAble Technologies which makes it possible for users to touch, feel and manipulate virtual objects. The tactile feedback provided by this device can be useful in biomedical applications.
Fuel Cell Systems Research Laboratory
This facility is equipped with a two-tier safety system to protect against accidental leakage of potentially hazardous gases such as hydrogen, carbon monoxide, and other hydrocarbons. Since fuel cell systems research involves the use (or production) of these gases, proper safety procedures as per accepted international standards of safety have been followed. The first tier of safety involves continuous ventilation at a controlled flow rate of fresh air intake and room air exhaust. In addition, computational fluid dynamics (CFD) studies were carried out to study the behavior of these gases in the event of a leakage under ventilated and non-ventilated conditions. Based on the results of these studies the intake and exhaust vents were sized and located. The intake and exhaust flow rates have been designed to be varied between 2000-5000 CFM (55-140 m3/minute) according to the usage. A second tier of safety consists of gas detectors deployed at strategic locations (aided by the CFD models) to detect accidental leakage of particular gases. These detectors are linked to an embedded controller-based data acquisition system that continuously monitors output from multiple detectors. If the concentration of any gas crosses a preset threshold, the controller either activates an audio-visual alarm or increases the fresh air and/or exhaust air flow rates in the ventilation system or shuts off supply of specific gases. It is expected that with this safety system in place, faculty members in other disciplines will be able to utilize this facility to carry out various activities pertaining to catalyst testing, reactor development, catalytic heat exchanger development, sensor development and thermal systems studies.
