Sabancı University Background
The technology is an electrooculogram based human-computer interaction/human-machine interface (HCI/HMI) system comprising wearable graphene textiles (headband, wristband), a signal acquisition system for obtaining biopotentials from the human body, and a processor for the processing of said biopotentials acquired through said signal acquisition system for enabling and facilitating human-machine interactions in various settings. Coil-based eye-tracking systems are invasive and are not meeting the non-clinical application needs. On the other hand, camera-based eye tracking setups fulfill the invasivity issue and display long-term functionality but they are hardly affordable due to their hardware (e.g. camera) and image processing requirements.
This invention is a smart gel-free wearable headband for detection, measuring, recording and evaluation for diagnostic purposes i.e. biopotential detection means such as electrooculography, electromyography and electrocardiography, and physical arrangements ().
This technology comprising gel-free wearable headband (such as dry electrode-enabled materials) provides eye movement-enabled machine interaction with wearable peripherals.
Thanks to this technology, human eye movement can be measured with pairs of electrodes. The electrodes are placed around human eyes so as to detect movement based on measuring cornea-retinal standing potential.
Human-computer interaction (HCI) or human-machine interface (HMI) system that enables control through signals produced by eye movement in different applications.
Electrooculogram-based human-computer interaction system with a wearable signal acquisition system based on graphene textile dry electrodes wearable on a human head.
An electrooculogram based interaction system provides a classification of detected ocular biopotentials due to different eye movements to generate different command signals. These signals can be used to remotely execute commands on objects, communicate with objects, control objects, and/or operate objects.
Improved performance in EOG signal utility
Suitable for recording ocular biopotentials are realized with a wearable graphene textile
Capability of the graphene textile integrated headband in EOG monitoring and automatic recognition of multiple eye movements.
More comfortable compared to “wet” electrodes
Easy to use
Applicable to use in electronic textiles (e-textiles) or smart garments.
Remotely execute commands on objects
Economical and non-invasive
The human eye and its movement have a tremendous source of potential for the rise of new applications in human-computer/machine interfaces (HCI/HMI) such as:
Headband/wristband for EOG, ECG, and EMG Monitoring
Headband/wristband for automatic recognition of multiple eye movement
Headband/wristband to remotely execute commands on objects
This technology can be used in Electrooculography (EOG) and eye tracking applications. The global eye tracking market size is expected to reach USD 1.75 billion by 2025, registering a 26.3% CAGR during the forecast period. This technology can be used in EOG, ECG and EMG Monitoring. The medical electrodes market was valued at USD 560.8 Million in 2016 and is projected to reach USD 732.4 Million by 2022, at a CAGR of 4.7%.
