Eye-tracking study - offline vs. online

Imagine that you have to conduct a quantitative (N=80) eye-tracking experiment containing 20 stimuli with additional questionnaires presented after the test. There are two ways to achieve it:

The offline way

You're probably familiar with a Tobii, GP3, or any other hardware eye-tracker, so you know what to do: go to your laboratory (assuming there's no lockdown at the moment), set up the study, and invite the participants. Here's the tricky part: before getting to the actual data, you have to spend hours collecting the data, asking the participants to visit you offline, and repeating the same routine for all of them. After some time (let's suppose you can handle 8-10 participants/day, so after two weeks) - you have the beautiful sets of data to work with, and the exciting part, the analysis, can finally begin.

The online/remote way

You set up the study in a web-browser. Use RealEye or one of many online panels to invite participants by sharing the study link. The very next day, you have the beautiful sets of data to work with, and the exciting part, the analysis, can begin.

One thing is sure:

Eye-Tracking research, just like many other industries is moving online, and it's happening right now.

What's different? What's the same?

You can expect lots of similarities using an online approach: the metrics from an online study are very much the same for the hardware option. In RealEye, you get:

  • heatmaps (gaze- and fixation-based), per participant and, aggregated,
  • clicks and mouse movements,
  • AOI tool with all the standard eye-tracking metrics (Dwell, Fixations, TTFF, Total Time, Ratio, and more)
  • participants' gaze recordings,
  • CSV files with raw data or calculated metrics,
  • answers from additional questions,
  • results' quality statistic and data quality grades,

There are also several differences:

Participants environment
  • Laboratory
  • Their home
  • offline laboratory
  • hardware devices
  • software license for data analysis
  • ability to invite participants to the lab
  • software license
  • online panel, can be a RealEye panel (read more)
Experiment duration factors
  • inviting and interviewing participants offline
  • collect results from dozens participants at the same time
  • collaboration using an on-line dashboard
Technical differences
  • "letter-size" accuracy
  • 60-240Hz
depends on chosen devices and the number of them, usually a couple of thousands USD Starting from $249 (learn more)

Interview with Andrew Duchowski

We're pleased to present our next episode of the short interview series: this time, we chatted with Andrew Duchowski from Clemson US, who told us about the current challenges and opportunities in the eye-tracking field.

Usado por universidades de todo el mundo

"We used RealEye for a lab assignment about selection attention to visual media, experimenting with several different short videos that exemplified different structural features of video that direct attention (e.g., cuts, motion, appearance of faces). Everyone in the class was able to provide eye tracking data for the videos, and analyze and discuss the data obtained from the entire class — all within a 90 minute lab.
The interface and analytics were excellent. We’d love to make the software a part of the class moving forward."

Preguntas frecuentes

Se ha demostrado que los estudios RealEye tienen una precisión de alrededor de 110 px. Esto permite analizar la interacción de los usuarios en un sitio web con una precisión que alcanza el tamaño de un botón único.
Predecimos el punto de mirada con una frecuencia de hasta 60 Hz.

Para un análisis en profundidad de la precisión del seguimiento ocular de la cámara web, consulte los siguientes artículos:

Puede contar con sus propios participantes o probadores de RealEye. Puede invitar a sus usuarios o panel y compartir el estudio con ellos mediante un enlace de participación. Todo lo que necesitan tener es una computadora/laptop con una cámara web y conexión a Internet.

También tenemos una red de panelistas de todo el mundo, principalmente del Reino Unido y los Estados Unidos. Los usuarios elegidos al azar se asignan a su tarea. Se llaman probadores RealEye. No les mostraremos los estímulos del estudio antes de que comience la prueba, por lo que su interacción será natural.

Solo hay pagos mensuales, por lo que no hay posibilidad de pagar por un solo estudio. Pero tenga en cuenta que puede cancelar su suscripción en cualquier momento (incluso en el mismo mes): mantendrá el acceso a la cuenta hasta el final del período de facturación.
Puede integrar fácilmente la herramienta RealEye con herramientas externas (por ejemplo, encuestas), pero también comparar los resultados obtenidos de otras herramientas utilizando nuestro archivo CSV (es decir, por la marca temporal - timestamp).
