Eye tracking
Scientists track eye movements in glaucoma patients to check vision impairment while driving. Yarbus eye tracker from the 1960s. History[edit] In the 1800s, studies of eye movement were made using direct observations. In 1879 in Paris, Louis Émile Javal observed that reading does not involve a smooth sweeping of the eyes along the text, as previously assumed, but a series of short stops (called fixations) and quick saccades.[1] This observation raised important questions about reading, questions which were explored during the 1900s: On which words do the eyes stop? For how long? An example of fixations and saccades over text. Edmund Huey[2] built an early eye tracker, using a sort of contact lens with a hole for the pupil. The first non-intrusive eye-trackers were built by Guy Thomas Buswell in Chicago, using beams of light that were reflected on the eye and then recording them on film. In the 1950s, Alfred L.

Tasa de rebote La tasa o porcentaje de rebote (en inglés, bounce rate) es un término utilizado en los análisis del tráfico de visitantes de las web de Internet. Un rebote (en inglés bounce) se produce cuando un navegante abandona el sitio después de haber visto una sola página web, en unos pocos segundos.[1] Muchos sistemas de estadística fijan el tiempo para que una visita se considere rebote en 30 segundos: un visitante se define como "desinteresado" si abandona la página antes de 30 segundos. El límite de 30 segundos es un valor de referencia que en algunas aplicaciones de software comercial, se está bajando a 5 segundos para evitar "counter terrorism" (gente que recarga las páginas varias veces para falsificar las estadísticas de una web). Un bajo porcentaje de abandono indica una buena organización de los contenidos y un aspecto gráfico correcto, que invita al visitante a continuar la exploración del sitio web.

Eye Tracking Software and Solutions - iMotions Eye tracking study reveals 12 website tactics Eye tracking studies have revealed valuable information about how people read and interact with websites. One study, Eyetrack III, published a summary of their eye tracking results for news sites. While this is just one eye tracking study focused on a particular type of site, I think there are instructive nuggets here for any informational website. In no particular order, here are 12 results I found particularly interesting. 1.Headlines draw eyes before pictures. But the participants in this study looked at headlines, especially in the upper left of the page, before they looked at photos when they landed on a page. 2. This means you should front-load your headlines with the most interesting and provocative words. 3. The implication is the same as before. 4. No nonsense. 5. Be careful with this one. 6. The point may be that anything at the top of a page will be seen immediately. 7. In online writing as in most ad writing, you have to forget normal paragraph development. 8. 9. 10. 11. 12.

Oculométrie Un article de Wikipédia, l'encyclopédie libre. Oculomètre chez un astronaute L’oculométrie (en anglais Eye-tracking ou Gaze-tracking) regroupe un ensemble de techniques permettant d'enregistrer les mouvements oculaires. Les oculomètres les plus courants analysent des images de l'œil humain enregistrées par une caméra, souvent en lumière infrarouge, pour calculer la direction du regard du sujet. En fonction de la précision souhaitée, différentes caractéristiques de l'œil sont analysées. Usages de l'oculométrie[modifier | modifier le code] L'oculométrie est utilisée comme technique de mesure pour la recherche en psychologie, en psycholinguistique, en ergonomie et pour les pré-tests de publicité. Exemples d'utilisation : Techniques d'enregistrement des mouvements des yeux[modifier | modifier le code] Typologie des mouvements de l’œil humain[modifier | modifier le code] On distingue trois grands types de mouvement de l’œil : Les mouvements sacadiques : en particulier les saccades exploratoires.

Apptimize Eye-Tracking Software Goes Mobile Go ahead, wake up your smartphone. No, don’t touch it! Just look at it. Wait for a second…and…yes! The day when eye tracking becomes a common feature in mobile gadgets may not be far off. But while the South Korean giants may be trailblazers in bringing gaze-based interfacing to the mobile market, analysts and researchers say their products only scratch the surface of what’s possible. Other innovators are working to build systems that not only detect face orientation but also follow the subtle motions of the head and eyes, allowing for more sophisticated applications. Eye-tracking systems for desktop computers have been around for decades—for instance, to conduct laboratory experiments and to help disabled people control their machines. The first hurdle is overcoming instability. Then there’s the problem of computing resources. In traditional image tracking, a system searches a large portion of each frame to identify relevant features, such as irises or eyelids.

15 Must-Know Facts on How People View Websites Do you know what is the first thing that your eye is drawn to on a website? And in what pattern do people scan your website? There have been many eyetracking tests on this subject and I’ll give you 15 most useful facts you should know. The picture below shows 3 different websites and where people look on them. As you can see, the more people scroll down, the more they lose focus and start mainly scanning your website. Here are the 15 facts you should know on how people view websites. Text attracts more attention than pictures. There you go.
