i2Media i2Media

i2media, is an independent company that specialises in evaluating user experience, organised and carried out two experiments to assess user preference of Eyeteq.

Eyeteq was tested on a pool of 90 volunteers, of which 60 colourblind and 30 colour-normal.

Two main aspects were evaluated, preference and acceptability.

Does a user prefer Eyeteq-treated video content over untreated content?

Regardless of preference, is the picture acceptable? I.e., is it acceptable to look at, or does it become too strange and unnatural?

Both parameters were assessed with side-by-side viewing of treated and untreated content.

The study was divided in various steps:

  • An assessment of the type and severity of colour blindness for each participant.
  • A calibration step in which a participant would use a slider to set their preferred Eyeteq strength over a video clip featuring different types of content.
  • A critical trial in which a participant would watch six different video clips with a fixed Eyeteq setting and would then answer some quantitative and qualitative questions.
  • 8 out of 10 deuteranomalous observers (the most common type of colourblind) preferred the Eyeteq treated content when they could choose the preferred setting in the calibration step.
  • In the critical trial, Eyeteq was preferred by colourblind viewers with a ratio of over 3:1 for colour-sensitive content.
  • Almost all observers (93%), both colourblind and colour-normal found the Eyeteq treatment to be acceptable.
  • When asked to consider pricing options, colourblind participants considered that an additional £44 on top of the price of a set top box would be good value for integrated Eyeteq functionality.
  • The second experiment that i2media carried out was a naturalistic study.
  • Only few colourblind observers (10) in a setting that simulated a realistic environment in which people would watch TV, with a sofa and a remote control. Questions here would be of more qualitative nature.
  • The remote control had some basic functions: they could use to change channel, adjust the volume, skip back and forward in the video and, most importantly, adjust Eyeteq settings.

In this experiment 8 out of 10 participants considered Eyeteq a worthwhile investment that would enhance their TV viewing experience. 9 out of 10 participants were likely to extremely likely to recommend Eyeteq to a friend or family member with colour blindness.

Eyeteq was perceived as being significantly beneficial for enjoyment when following particular sports such as football and rugby due to the increased ability to differentiate between team colours.

It should be noted that participants in this experiment had already taken part in the previous. Participants who previously had a positive experience were more likely to have a positive attitude towards Eyeteq and therefore more likely to volunteer for this follow-up study.
