[visionlist] [cvnet] Robert Musil and the Color Wheel

Wed Mar 27 11:11:51 -04 2019

Color is not my thing, so I could have missed some older references, but when reviewing the history of perceptual constancies in my “3D shape” book, I cited Alhazen (1083) for a description of what resembles Maxwell’s top. See pp. 144-5 in:

Alhazen (1083/1989) The optics. Books 1-3. (Translated by A.I. Sabra, London: The Warburg Institute).

However, in 1855 Maxwell invented the colour top for mixing colours (https://royalsocietypublishing.org/doi/full/10.1098/rsta.2007.2178). What, then, did Musil invent in 1906?

BTW the inventor of that interesting and useful contraption was the Austrian writer Robert Musil (who studied engineering first, then rejected academia to write important novels):

Sandro, 

Figures 7, 8, 12, and 13 show an episcotister, I believe.  It is a color wheel that allows you to change the proportion of 2 colors (say white and black) while the disk is spinning at high speed. Can’t touch German machines!

Hello, 

Here some indications:

Figures 12-13 : Farbenkreisel zur beliebigen Verstellun der Sektore, während der Rotation (Couloured disc on which the size of the sectors may be varied during rotation) may be E. Zimmermann, I do not see details on the photos but it is an handvariator.

Figure 6 : Graphische chronometer nach Jaquet (Jaquet's graphic chronometer)

Figure 7 : Einfacher Farbvariator (simple colour motor variator)

Figures 4 and 5 : Tourenzähler (Speed indicator)

Figure 9 : Deprez signal type (but I am not sure)

The other instruments are unknown to me. But photos do not indicate details.

I have not in my possesion the Heinrich Diel catalogue. I think you can find informations into this old catalogue.

Best wishes,

Serge

Cher collègue, 

Chercheur en psychophysique à l'INCC (ex-LPP, ex-LPE) et visiteur à votre exposition de vieux instruments de psychologie au siège de l'Université (très intéressante, mais j'aurais apprécié plus d'explications), je viens de recevoir ce message d'un collègue slovaque sur CVNET, une liste de diffusion sur la vision :

Hello everyone!

At the faculty we are doing exhibition of old psychological apparatus for which we need to find out their names and functions. We found many of them, but some of them are still unknown to us. If someone has any information for any of them, I would be very grateful if you shared it with me.
