1. Survey results
The survey was given to get familiar with people who wear glasses and their experience using 3D-glasses. We can learn from these experiences
and improve our new 3D-glasses by avoiding existing problems. The results of this survey will be an input for the concepts later on in the
designing stage.
The survey has been holding on several locations such as: cinema in Amsterdam, cinema in Rotterdam and the Industrial Design faculty in Delft.
In total 24 random people were pleased to answer the questions. Along the group most given answers were similar to the others. Our survey
provides the following results.
Question 1: Which type of glasses did you used in the past?
Image 1 Image 2 Image 3
As result of the first question you can see that largest part of
the respondents did make use of the glasses from image 1. These are
the famous glasses used in most Pathé cinema’s. A bit more then a quarter of the group
let us know they used the glasses from image 2. These are also used in a few Pathé
cinema’s. The glasses of image 3 were not used by anyone whom filled in the survey.
The remaining quarter let us know they used a different type of 3D-glasses then the
one of our images.
Question 2: What is your eye- strength / intensity?
Most respondents have their unique eye-strength and that is why there is a big range of answers. Almost all respondents were short-sighted and
have an average of – 1,5. In order to find out if there is a relation between eye-strength and wearing both glasses, we came up with question 3.

2. Question 3: Do you wear both glasses (own and 3D-glasses) during the
movie?
The circle does do most of the speaking here. 20 out of the 24 respondent
let us know they use both glasses. And 3 out of the 4 remaining let us know
they wear lenses instead. This is because without any help from glasses or
lenses they will not have a sharp image from the movie screen.
Question 4: Where are the points of contact between glasses?
Points of contact with frame

4. Conclusion and input for our concepts:
The most common 3D-glasses at this moment is the one from image 1 (XpanD). During our visit to the Pathé, they let us know in the future all
glasses from image 2 will be replaced by the ones from image 1. This means the amount of 3D-glasses from image 1 will even increase. That is
the reason why we will focus on the XpanD with all its electronics. Almost all users wear both glasses during the 3D movie. Therefore our
improved 3D-glasses will be attached to regular glasses or fit over regular glasses. The new design does not only need to improve the looks but
also avoid contact with the glasses, nose and frame as much as possible. Positive points such as sight-angle and vandal-proof should remain. We
have to keep in mind that it is not possible to remove all negative points because each individual has its different experience. But it would be
nice if we could reduce it to as less as possible.
