Augmented reality thought experiment.
Please suppose that the QR code is on a wall.
Can the buttons be pressed using a human hand?
Please click to get an enlarged picture, then again for full size.
I used these websites.

The format for each of the button placing commands is as follows.
x, y, z, button, colour;
where x is horizontal from left to right, centred on the QR code,
y is into the wall, centred on the QR code,
z is vertical, centred on the QR code,
Thus the three buttons in an augmented reality view are in a horizontal row one metre in front of the QR code.
Can the buttons be pressed using a human hand?
William
Reading about QR codes, it seems that if I do not use lowercase letters and only use capital letters in the text of the QR code that that will reduce the size of the QR code.
So I can try that.
I cannot get the png file to become added. Alfred, help please!

I saw the image before, William, and I can still see it now. Please help me to help you by describing what happened when you tried to add the PNG file; in particular, please quote any error messages you got.
If you’re still struggling to add it as a forum attachment you can upload it to your web space and use its URL as your image link.
Thank you.
Here is an attempt to add the same file as in the first post in this thread.
A preview shows it working now.
No message about it having been reported.

So here is the picture for that, buttons2.png
If I cut the wording down from
UNIT, METRE;
-1, -1, -0.1, BUTTON, RED;
0, -1, -0.1, BUTTON, BLUE;
1, -1, -0.1, BUTTON, GREEN;
to become
U, M;
-1, -1, -0.1, B, R;
0, -1, -0.1, B, B;
1, -1, -0.1, B, G;
that does reduce the size of the QR code.
So add another object into the augmented reality space.

U, M;
-1, -1, 0, M;
1, -1, 0, D;
0, -1, 1, F, Y;
-1, -2, -0.1, B, R;
0, -2, -0.1, B, B;
1, -2, -0.1, B, G;
So four procedures have been added to the design, of which three are being used in the latest example.
x, y, z, MOVEPEN;
x, y, z, DRAW;
x, y, z, CLOSE;
Closes the shape directly back to the most recent MOVEPEN location.
x, y, z, FILL, COLOUR;
Closes the shape directly back to the most recent MOVEPEN location and fills with the specified colour. Only defined for a shape where all of the points are in the same plane.
Y in the FILL example is for YELLOW.
Suppose, temporarily, in case I decide to change it later, that clicking on a red button rotates any object yaw-wise by ten degrees clockwise when viewed from above, rotated about the vertical axis that passes through the centre of the starting bounding box of the object.
Suppose, temporarily, in case I decide to change it later, that clicking on a green button rotates any object yaw-wise by ten degrees counterclockwise when viewed from above, rotated about the vertical axis that passes through the centre of the starting bounding box of the object.
Suppose, temporarily, in case I decide to change it later, that clicking on a blue button is necessary if one wishes to click on either the red button or the green button a second time before clicking on another button.
With a suitable viewing device, with suitable software, one could have a dynamic augmented reality artwork, where a person could manipulate the artwork without needing to touch any physical buttons or other controls or the screen of the device.
I am remembering a system that I designed in the 1990s and about which I wrote both some text and a song.

Oh, and this from 2007.
http://www.users.globalnet.co.uk/~ngo/euto2007.htm
I could not find the original midi file, but here is a link to a video of the same song as an instrumental played on saxophones.
So add another object into the augmented reality space.

Can you imagine the view of the augmented reality scene if the red button is clicked eight times, with a click of the blue button after each click of the red button?
William
A good number of views of the thread yet nobody has posted about the 3d model that I have designed.
Is it that nobody is interested or does it seem too trivial to discuss or too complicated or too unclear to discuss please? Or something else, such as people being too busy to spend time discussing it?
I am hoping for a lively discussion please.

Thank you for replying.
I will try to draw a picture and try to write some text to support the picture.
Thank you again.
Best regards,
William
Please imagine a person going into an art gallery and now standing facing a white wall, standing about 3 metres (about 10 feet) from the wall..
On the wall there is a picture. The picture is square, each edge about 2 feet, about 60 centimetres, along each edge. The picture consists solely of a large QR code.
William
Continuing ...
Suppose that the person has a hand held tablet device.
The person is holding the device in a landscape orientation with its camera pointing towards the QR code that is in the picture that is on the wall.
William
Continuing ...
Please imagine that the tablet device has running on it a software application that can read the QR code and if the QR code contains commands that have been devised for this thought experiment then it can obey them.
These commands have the effect of superimposing on the view of the area that comes from the camera, images such as a large coloured button, like a large version of a keyboard key, or a filled yellow triangle, or a filled blue square, or an unfilled triangle where just the edges of a triangle are displayed.
A coloured button is of a preset size.
A triangle or a square is specified by a sequence of commands.
William
Continuing ...
Here is the example code thus far for this thought experiment.
The code in the QR code is as follows.
U, M;
-1, -1, 0, M;
1, -1, 0, D;
0, -1, 1, F, Y;
-1, -2, -0.1, B, R;
0, -2, -0.1, B, B;
1, -2, -0.1, B, G;
This being a compacted form of the following.
Unit, Metre;
-1, -1, 0, MovePen;
1, -1, 0, DrawLine;
0, -1, 1, CloseLoopAndFillWithColour, Yellow;
-1, -2, -0.1, Button, Red;
0, -2, -0.1, Button, Blue;
1, -2, -0.1, Button, Green;
In those commands that start with three numbers, these are, respectively, x from left to right, y going into the QR code, z going from down to up.
William
Continuing ...
So the screen should display on the tablet sshould look something like the following, showing the gallery wall, the picture with the QR code and the buttons and the triangle.
William
Continuing ...
Here is a graphic to try to indicate the effect of click the red button, namely rotating the yellow triangle about its vertical axis by ten degrees, clockwise as viewed from above. The diagram is not exact, but hopefully will give a helpful indication of my meaning.

Can you imagine the view of the augmented reality scene if the red button is clicked eight times, with a click of the blue button after each click of the red button?
William
Here is a graphic that is intended to give an indication of the the effect of clicking the red button eight times, with a click of the blue button between each such click of the red button. The yellow triangle has rotated about its vertical axis by 80 degrees. So the lower vertex of the triangle at the right of the picture has moved nearer the person and the lower vertex of the triangle at the left of the picture has moved further away from the person.
The image is not exact, but hopefully gives a helpful indication.
I am thinking of a button being clicked by the person moving a hand down onto the button, such that the software in the tablet device detects that. That is, a real physical hand of the person is deteted as being in the same place as the "let's pretend" augmented reality button.
William
Too complicated.
Have my later posts and the pictures been helpful?
William
Incidentally, each of the illustrations was produced as A3 size artwork, so that if I decide to get some prints that the artwork is at the right size for big enough yet budget price laser prints.
The artwork is produced using Serif Affinity Designer. The QR code is bit map and imported, everything else is vector and generated in Affinity Designer.
The buttons are each a trapezium, the red button and the green button have both had shear applied to try to produce a perspective-like picture.
The yellow triangle was drawn using the Pen Tool and the positions of the points set using the Node Tool.
