Our aviation related projects are developing eye gaze controlled Multi-Function Display (MFD) and Head Mounted Display system (HMDS) and can simultaneously estimate pilotsí cognitive workload from ocular parameters. As part of the research we collected ocular parameters during air to ground attack dives and -1G to +5G constant G-load manoeuvres in combat aircrafts. We also developed and demonstrated eye gaze controlled virtual and real flight simulators in Aero India 2019 and Defence Expo 2020.

Recording Ocular Parameters at +5G

Main Results

o   We reported that pilots can undertake representative pointing and selection tasks at less than 2 secs on average and the accuracy of COTS eye gaze tracking glass is less than 5ļ of visual angle up to +3G, although it is less accurate at -1G and +5G. We used these results in developing a multimodal head and eye gaze movement based HMDS and in a user study involving standard ISO 9241 pointing task. The average pointing and selection times was significantly lower in the proposed system compared to traditional TDS.

o   Ocular parameters like rate of fixation is significantly different in different flying conditions and significantly correlated with rate of descent during air to ground dive training task, normal load factor (G) of the aircraft during constant G level turn manoeuvres and pilotís control inceptor and tracking error in simulation tasks.

We have developed a finger movement and eye gaze controlled interactive Head Up Display (HUD) for car that can also simultaneously estimate driversí cognitive load using a new machine learning algorithm involving ocular parameters. We validated the interactive HUD through simulation and in-car studies. The work is extended to autonomous vehicles too by integrating the cognitive load estimation module with object detection Convolutional Neural Network (CNN) models. As part of the study, we compared existing CNNs like RetinaNet, YOLO and maskR-CNN for Indian road dataset with respect to accuracy and latency of detecting different traffic participants.

Main Results

o   User studies show the interactive HUD improves driving performance in terms of mean deviation from lane in an ISO 26022 lane changing task compared to touchscreen system and participants can undertake ISO 9241 pointing tasks in less than 2 secs on average inside a Toyota Etios car.

o   Average velocities of saccadic intrusion increases with increase in cognitive load and recording saccadic intrusion and eye blinks for 6 s duration can predict driversí instantaneous perception of developing road hazards.

o   Accuracy of Mask R-CNN is significantly higher than YOLOv3 and RetinaNet while evaluating these models on novel classes of objects such as animals, autorickshaws, caravan in Indian road dataset. We have also tested latency of the CNN models and found that latency of YOLOv3 is significantly lower than other two models and RetinaNet is significantly faster than Mask R-CNN.

Our projects on Assistive Technology and Inclusive design are covering a wide range of abilities including users with severe speech and motor impairment, students with learning disabilities and elderly users with hearing impairment. We deployed eye trackers and a set of eye gaze controlled assistive software and robotic manipulator at the Spastic Society of India, Chennai, India. We compared ocular parameters of students with learning disabilities with their able bodied counterpart, deployed online multilingual cognitive and auditory test battery and investigated website and smartphone usage patterns by elderly users. We work with International Telecommunication Union to promote accessibility of audio visual media by chairing an Inter-Rapporteur Group on Audio Visual Media Accessibility (RG AVA).

Users with severe speech and motor impairment operating a robotic manipulator through webcam based eye gaze tracker

Main Results

o   Users with SSMI can statistically significantly select correct elements on screen in an eye gaze controlled interface faster when elements were organized at their preferred screen positions than random organization.

o   Using our bespoke eye gaze controlled interface, able bodied users can select one of nine regions of screen at a median of less than 2 secs and users with SSMI can do so at a median of 4 secs. Using the eye gaze controlled human-robot AR display, users with SSMI could undertake representative pick and drop task at an average duration less than 15 secs and reach a randomly designated target within 60 secs using a COTS eye tracker and at an average time of 2 mins using the webcam based eye gaze tracker.

o   Total number of eye gaze fixations and regressions (backward gaze movement) were statistically significantly correlated to the reading ability of students.

We are developing an interactive sensor dashboard and multimodal CoBot for supporting Industry 4.0 initiative. We are investigating different visualization techniques of sensor reading in 2D and 3D environment. The multimodal CoBot allows to control a robotic manipulator through multiple modalities like eye gaze, gesture and speech. Earlier we also developed image processing algorithms for automated inspection of rubber sheet for a shoe making MSME and Printed Circuit Boards (PCB) for detecting correct orientation and type of IC chips using webcam and shape detection algorithms. We have developed

a prototype system using a Kinect that can detect bad leaning posture by measuring the difference between the neck-spine and hip-spine joints in the skeleton figure of Kinect. Following RULA guidelines, it raises an alert when the neck or torso is inclined more than 60 ͦ.


Main Results

o   We have evaluated shape detection algorithms in different lighting conditions (indoor, outdoor, and controlled light source) and best shape detection result is obtained in YCbCr color space using bounding box shape descriptors for 2500 Lux using LED.
