Figure 11: Superimposition of the 6 eye-drawings of my left hand

Figure 11 is a drawing made up of a superimposition of the six eye-drawings in my previous post. When I am eye-drawing from life, I cannot refer to the visual of the ‘physical drawing’ being created as this is only generated during post-processing. Many drawers highlight the importance of this reference in their practice, as does Richard Talbot who specifically talks about perspective drawing and its thinking about the orientation; “to the relationship with the surface of the paper – the picture plane” (Talbot, 2008, p. 45).
The methodology I have been using so far is to import the recorded eye-tracking coordinates (as a set of points) into a 3D software like Rhino, from where I can process them into drawings using a polyline curve (which follows the temporal value of each point). At this stage, the eye-drawing sits in a virtual 3-dimensional space, and I navigate this with the same understanding of when physically drawing on a picture plane. I had not noticed that this was my reasoning while developing these eye-drawings until I recently read an interview of Michael Kidner where he talks about how he governed 3D Studio Max through knowledge coming from his; “previous practical pursuits in the material world” (Eames, 2008, p. 139).
Perhaps it was also this way of thinking/doing that drove my intuition to superimpose the hand eye-drawings. When merged into one image, I see the eye-drawings become an extended representation of moments in time, highlighting the fact that even though while eye-drawing I was attempting to follow a ‘contour’ through an invisible trace, outlines are a synthetic construct and do not exist in nature. There are, therefore, infinite possibilities to its representation as the history of drawing illustrates for us.
In this sense, the image of Figure 11 becomes a continuous eye-drawing (a kind of seismography of the drawing eye) other than 6 superimposed eye-drawings of 15 seconds each.
Is the practice I am dealing with a process of relearning, learning or unlearning (with regards to drawing/seeing/looking/gesturing)? The practice is resulting in new visions and visuals, and the technologies of the eye-tracker together with the 3D software are making them possible. I cannot however mistake the technology for the idea. The machine is not aiding my way of drawing or looking at the world, but is making an image/views possible, which was/were previously unnoticeable. In this context, I elaborated Figure 12, which includes a generative development between the 6 eye-drawings in Figure 11. These algorithmic/generative/computer-aided drawings will be tackled in future posts.

3: Eye drawing the hand

This experiment came right after my previous posts, using the same set-up, eye-tracker and calibration. Just as in my previous recordings, my left hand was placed on the table in front of me, and the intention was now to eye-draw it (repeatedly). The scanpaths in my previous posts dealt with eye-tracking other than actual eye-drawing, as both scanpaths are the traces of my eye while drawing with my right hand. This post illustrates six eye-drawings resulting from the set-up mention above, and they lasted approximately 15 seconds each to record.
This is 9 seconds less than the previous blind-contouring exercise, which does not seem to be a great difference until one calculates that they are 37.5% of the (earlier) time spent blind-contouring. I am flagging this up not because I am interested in the mathematical calculation of the act of drawing (or eye-drawing), but because this can lead me to several new questions about my own practice. It can be argued that the blind-contouring exercise took longer due to the hand co-ordination involved while drawing (eye-drawing is more ‘direct’), but I think there can be other variables to consider.
What happens if I try to consciously go slower? Can I actually go slower? The eye movements are quite difficult to control and saccades are always in motion. How can this ‘trace’ relate to the line/mark/contour in drawing, and how does it compare to the notion of ‘reducing’ the mark before it quickly transforms into a defined image? I am not (spatially) aware of the mark while eye-drawing, or rather, the mark is in my head (not on a support). I can only tangibly relate to it during post-processing (virtually).
Does the distance I was eye-drawing my hand from naturally influence the speed (and other factors)? Distance has always been a crucial issue to take into account when drawing; both physically and mentally.
I am also intrigued by the fact that it seems to have automatically taken about 14-16 seconds for every eye-drawing to manifest (six times in a row). Is this an indication of habituality? All six eye-drawings unconsciously started from the back of my hand, moving clockwise through my fingers and ended below the wrist. When hand-drawing I am aware that I make a lot of conscious (and sometimes habitual) decisions; where to start on my page, where to start on the object I am gazing at, etc. What happens if I train myself to be more aware of where to start and how to ‘move’ while eye-drawing (or should I not)?
Another important mention are the fixations. Arguably the fixations in the eye-drawings represent some kind of hesitation in figuring out where I am in the ‘drawing’ (relating directly to somewhere in my mental imagery). It is also interesting to note that the 6th eye-drawing manifests an unconscious ‘inattention’ towards the completion of the drawing, resulting in a ‘misdirection’ of the saccades. These unpredictable registrations can be of most interest when treating the practice of eye drawing in context of its unique perceptive moments in time and space.

1: Drawing the hand

This experiment consisted in eye-tracking my eye-movements while drawing my left hand. A monocular Pupil Labs Core eye-tracker was used, tracking the gaze of my left eye. Figure 1 shows my hand-drawing of my left hand and Figure 2 shows my eye scanpath while drawing it. The drawing took 50 seconds to complete (and consequentially Figure 2 is the result of 50 seconds of data).
My practice-based research question consists in the attempt to explore ways of drawing with my eyes, but this exercise visualises my eye movements during my usual hand-drawing practice (which would be useful for future comparisons).
I feel that wearing the eye-tracker does not influence me much due to its unobtrusive nature, and even though at first I am aware and cautious about the fact that I am recording my acts, this immediately wears away as I concentrate on the practice of drawing. My main questions when drawing from life concern the what and where to look at. Many definitions of drawing have been attempted, and the ones I acknowledge most are those which seem to allude to the inconclusive and deliberately attempt a ‘non-definition’ of drawing — perhaps due to the ‘ghostly’ and ‘unfinished’ nature of drawing (and the practice) itself. It is worth noting that I am looking at drawing with my eyes for the sake of the act of drawing per se, and not to regard it as a sketch, as a way to problem-solve or any other possible drawing adaptation.
Figure 2 reminds me of several important points. There is more gazing activity happening around the hand area, which intensifies along its ‘contours’. This evidences the looking and seeing quest of identifying an outline/contour while drawing. Perhaps it is also evident of the induced/habitual ‘rule’ when drawing from life; to draw what you see and not what you know. Drawing from life is both a hesitant and yet, precise activity.
