Such strategies can be used as controls for simple games or for operating programs for spelling words. Particular eye-blink patterns have the specific keyboard or mouse commands assigned, e.g., a single long blink is associated with the TAB action, while a double short blink is a mouse click. Specific mouth moves can also be included as an additional modality. The eye-blink-controlled systems distinguish between voluntary and involuntary blinks and interpret single voluntary blinks or their sequences. Such systems use two kinds of input signals: scanpath (line of gaze determined by fixations of the eyes) or eye-blinks. Most of the existing methods for gaze communication are intrusive or use specialized hardware, such as infrared (IR) illumination devices or electrooculographs (EOG). Gaze controlled and eye-blink-controlled user interfaces belong to the second group of systems suitable for the people who cannot speak or use their hands to communicate. BrainвЂ“computer interfaces hold great promise for people with severe physical impairments however, their main drawbacks are intrusiveness and need for special EEG recording hardware. Such interfaces enable to operate virtual keyboards, manage environmental control systems, use text editors, web browsers or make physical movements. 6.ДЇor severely paralyzed persons who retain control of the extraocular muscles, two main groups of humanвЂ“computer interfaces are most suitable: brainвЂ“computer interfaces (BCI) and systems controlled by gaze or eye-blinks.ДЄ brainвЂ“computer interface is a system that allows controlling computer applications by measuring and interpreting electrical brain activity. Section 4 presents the eye-blink controlled humanвЂ“computer interface based on the proposed algorithm. The proposed eye-blink detection algorithm is described in Sect. Section 2 of the paper includes an overview of earlier studies on the interfaces for motor impaired persons. Separate short eye-blinks are assumed to be spontaneous and are not included in the designed eye-blink code. The detected eye-blinks are classified as short blinks (shorter than 200В ms) or long blinks (longer than 200В ms). The proposed algorithm allows for eye-blink detection, estimation of the eye-blink duration and interpretation of a sequence of blinks in real time to control a non-intrusive humanвЂ“computer interface.

The system, capable of processing a sequence of face images of small resolution (320В Г—В 240 pixels) with the speed of approximately 30 fps, is built from off-the-shelf components: a consumer-grade PC or a laptop and a medium quality webcam. In this paper, a vision-based system for detection of voluntary eye-blinks is presented, together with its implementation as a HumanвЂ“Computer Interface for people with disabilities.

Alternative means of interacting for persons who cannot speak or use their limbs (cases of hemiparesis, ALS, quadriplegia) are their only way of communication with the world and to obtain access to education or entertainment.ДЄ user friendly humanвЂ“computer interface for severely movement impaired persons should fulfill several conditions: first of all, it should be non-contact and avoid specialized equipment, it should feature real-time performance, and it should run on a consumer-grade computer. In recent years, the development of alternative humanвЂ“computer interfaces is attracting attention of researchers all over the world. Therefore, there is a need for developing alternative methods of communication between human and computer that would be suitable for the persons with motor impairments and would give them the opportunity to become a part of the Information Society.

All these devices require manual control and cannot be used by persons impaired in movement capacity. Commonly used input devices include the following: keyboard, computer mouse, trackball, touchpad and a touch-screen.

HumanвЂ“Computer Interface (HCI) can be described as the point of communication between the human user and a computer.
