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:

Offline
Participants environment
  • Laboratory
  • Their home
Requirements
  • 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
Costs
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 o 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."

Perguntas Frequentes

Os estudos do RealEye comprovadamente têm precisão de aproximadamente 110 px. Isso permite analisar a interação dos usuários em um site com precisão, atingindo o tamanho de um botão único .
Prevemos o ponto de observação com frequência de até 60 Hz.

Para uma análise aprofundada da precisão do rastreamento ocular por webcam, verifique os seguintes artigos:

Seus participantes próprios ou do RealEye. Você pode convidar seus usuários ou painel e compartilhar o estudo com eles usando um link de participação. Tudo o que eles precisam é de um laptop / PC com uma webcam.

Também temos uma rede de respondentes do mundo todo - principalmente do Reino Unido e dos EUA. Usuários escolhidos aleatoriamente podem ser atribuídos à sua tarefa. Eles são chamados de testadores/respondentes RealEye. Não mostraremos seus estímulos antes do início do teste, portanto a interação deles será natural.

Há apenas pagamentos mensais, portanto não há possibilidade de pagamento por estudo. Mas lembre-se de que você pode cancelar sua assinatura a qualquer momento (mesmo no mesmo mês). Você manterá o acesso à conta até o final do período de cobrança.
Você pode integrar facilmente a ferramenta RealEye a ferramentas externas (por exemplo, pesquisas), mas também comparar os resultados obtidos de outras ferramentas usando nosso arquivo CSV (ou seja, pelo carimbo de data / hora).
