user feedback

Today, research has been carried out into hat users think of the design and what they would recommend. Two questions were asked to the users. The first question was the same question as was asked during the earlier research at the beginning of the design process. This question was: The truck is in front of a red traffic light and wants to turn right. You arrive with your bike where would you stand? A, B, C, D, E, F or G. (see below)

We have made a prototype and show it to the user. This prototype was 1:20, presumably the scale did influence the results of the research because the images were smaller than in reality.

For the second question we showed the user different shape variations of the truck and asked which they found the most clear.

The tips of the user about our design:

Contrast

Use the colors black and white because they are the biggest contrast of each other.

The dead corners do not stand out.

The red color of the dead corners does not stand out because the trucks are also red, perhaps you can indicate the safe zones with green instead of working with green.

Put a frame around the sticker so that the sticker stands out better. Because now it seems like

Lights

The green lights are confusing because I now have the idea that it is safe to continue driving.

The lights on the side of the truck are only visible when you are on the side yourself. You only see this at the last moment.

At the lights at the back, I find the green lights unclear, red lights would ensure that I know much more clearly where it is dangerous.

The lights do not help on the side.

Use reflective pieces.

I thought the lights were decoration.

Sticker side truck

The lights and the color gradually change from red to green, so it is not clear to me from where it is dangerous. It would help if it directly changes color.

I would not follow the arrows on the side because I do not turn around when I am standing in the blind spot.

By group pressure I would not follow the arrows but just drive forward.

Sticker on the back of the truck

It is not noticeable that a truck is shown.

Observations

When asking the first question, nobody looks at the back of the truck.
