Scientists develop a real-life 'cyclops lens' that emits an infrared laser pointer to track the wearer's eye movements

Infrared laser is fitted to a regular-size contact lens and can be worn normally 

Emits a laser beam which is detected by IR camera mounted on glasses frame 

Prototype shows the technology works in real time for gaze recognition 

Was named 'cyclops lens' after the character in the X-MEn movies and comics

착용자 눈 움직임 추적 적외선 레이저 방출 '사이클로프 렌즈' 개발

    과학자들은 엑스맨의 사이클롭스에서 영감을 얻어 착용자가 보고 있는 어떤 것이든 빨간색 레이저를 가리키는 콘택트 렌즈를 만들었다.

일반 크기의 콘택트렌즈에는 사용자가 보고 있는 방향을 가리키는 수직 캐비티 표면 방출 레이저(VCSEL)가 장착된다.

프랑스 엔지니어들은 시력 인식에 사용할 수 있는 작업 시제품을 만들기 위해 기성 부품을 사용했다.

시선 인식은 새로운 연구 분야로 컴퓨터 시스템의 다음 개척지가 될 수 있다.

터치스크린이나 마우스를 사용하여 장치를 제어하는 대신, 시선 인식은 사용자가 보기만 해도 디스플레이의 옵션을 선택할 수 있게 한다.

디자인은 각 눈에 콘택트 렌즈를 착용하고 안경 프레임에 장착된 외부 카메라 시스템이 사람이 보고 있는 곳을 추적한다.

엑스맨의 유명한 영웅을 지칭하여 '사이클로프 렌즈'라는 이름이 붙여졌다.

난테스의 IMT 아틀란티크에 전문가들 실험에서 콘택트 렌즈는 회전하는 인공 눈에 장착되었다.

빔 스플리터를 눈과 안경 앞에 배치하고 두 빔을 각각 눈에서 하나씩 배치했다.

'이 빔 스플리터는 두 레이저 스팟에서 생성된 IR 빔을 반사하도록 코팅된 반면 눈에 대해서는 투명하다.' 라고 연구진은 말한다.

Scientists have taken inspiration from X-Men's Cyclops and created a contact lens that points a red laser at whatever the wearer is looking at. 

The regular-size contact lens is fitted with a vertical cavity surface emitting laser (VCSEL) which points in the direction the user is looking. 

French engineers used off-the-shelf components to create a working prototype which can be used for gaze recognition. 

Gaze recognition is a budding field of research and could be the next frontier for computer systems. 

Instead of using a touchscreen or a mouse to control a device, gaze recognition would allow users to select options on a display just by looking at them.  


Pictured, the electronics inside the contact lens prototype (left) and as worn on a human eye (right).  The system is described as 'a new eye tracking system using an infrared (iR) laser pointer embedded into a wireless smart contact lens'

The design relies on a contact lens being worn on each eye and an external camera system, fitted to a spectacle frame, tracks where the person is looking. 

It has been given the name 'cyclops lens' in reference to the famous hero of the X-Men comics 

In an experiment set up by the experts at IMT Atlantique in Nantes, the contact lenses were fitted to an artificial eye which rotates. 

A beam splitter was positioned in front of the eye and glasses and to locate the two beams - one from each eye. 

'This beam splitter is coated to reflect the IR beams generated by the two laser spots while being transparent for the eyes and coated to avoid unwanted reflections,' the researchers write in their study. 

This diagram describes the basic layers and components, as well as dimensions, of the `new-era contact lens prototype.  French engineers used off-the-shelf components and say it could be made lighter and more efficient with custom materials 

An infrared camera then records where the laser has been reflected and software plots where the two beams from both eyes would meet, indicating where the person is looking. 

'In our system, detecting the laser beam direction will directly provide the gaze direction,' the researchers say. 

Video published alongside the study shows the system working in real time.
