8: What is eye drawing?

Figure 22: 5 superimposed eye-drawings of my right hand

Figure 23: Generative development of 30 tween curves between the 5 eye-drawings in Figure 22

What universe of drawing does the practice of eye drawing really fall under? I feel that the performative element while eye-drawing my chosen subject matter is embedded into my previous knowledge of drawing. I seem to automatically adapt certain methodologies which are comparable to techniques that have a long history in drawing (and which I should both highlight and challenge). A primary example is the intention of attempting to ‘contour’ along the subject being looked at and to present them as such (as in Figure 22).
At the same time, the adaptation of the eye-tracker into a drawing medium is in itself allowing me to question several acts of looking while drawing, and by choosing the hand (and body) as subject matter, the practice is being given a specific context. Therefore, during the act of eye drawing and during my first reactions to the data processing, the general mood is that of drawing ‘as drawing’.
However, examples like Figure 22 contain more information other than the eye-drawn contours. Within the virtual space, they exist as 5 individual curves in a three-dimensional field constituting in several possible viewpoints (Figure 22 is closest to a conventional drawing result). Each curve (eye-drawing) consists in a set of time-based coordinates, along with several other data provided by the eye-tracker.
The mood of drawing ‘as drawing’ starts to fade within this context and Figure 23 is essentially a product of this condition. It becomes a computer-assisted drawing, or a computer-generative drawing. In Figure 23, the curves stop being referred to as eye-drawings and become information for a set of instructions — specifically, 30 tween curves in the space between every 2 curves (eye-drawings). In this scenario, the eye-drawings become data/information which guide the algorithm in order to create the instructed tween curves. The generation of the tween curves is generative and I therefore do not have full control on its appearance. However, I can vary several inputs like; the number of tween curves, viewpoint of the exported image, distance between curves (eye-drawings) and positioning of the latter within the virtual space, among other options (which I will continue to explore through the practice). The linear form of the eye-drawings, are themselves the primary influence for results such as Figure 23.

7: Animated eye-drawings

Figure 19: Frontal view of Figure 15

Figure 20: Stop-motion animation between the 3 eye-drawings in Figure 15

I experimented with a different post-processing development for the 3 eye-drawings previously shown in Figure 15. A frontal viewpoint of the rotating model was chosen, as illustrated in Figure 19. The curves/drawings within the image were individually exported and these were in turn imported into a video editing software (acting as video frames). The export resulted in the moving image illustrated in Figure 20.
Several questions can be raised by this methodology, concerning both the conceptual and its technical/practical aspects. Firstly, where do these animations stand within the practice of eye-drawing as described in my previous posts?
An animation emerging out of a hybrid of subjective eye-drawings of the body (hand) and computational (algorithmic) generation is definitely an interesting call for more experimentation.
Figure 21 is another animation resulting from a different set of hand eye-drawings.

6: Further sculptural developments

Figure 17: Sculptural development of three lofted eye-drawings of a hand

The visual quality exerted by the images posted in this blog so far, flirts somewhere between algorithmic drawing, generative art and representational drawing. This also brings to mind that as in contemporary hand-drawing, I am not interested in eye drawing for a ‘realistic’ and ‘academic’ rendition of my subjects. I am instead interested in certain traditional methodologies, such as the drawing of the hand and the life class, because I find it meaningful to revisit such drawing activities from a contemporary lens.

5: Sculptural developments

Figure 15: Rotating animation illustrating the sculptural development from three intersecting eye-drawings of a hand

Eye drawing a subject from different viewpoints has an exploratory feel to it. It can arguably find its roots in ‘Cubist’ ways of dealing with our perception of the world, but in contemporary times I cannot not help thinking about the phenomenon and popularisation of 3D scanning (and photogrammetry). In experiments like Figure 13 and Figure 14, I am essentially attempting a ‘synthetic’ 3D ‘contour-like’ scan of my hand by drawing with my eyes.
Figure 15 illustrates a rotating animation of the intersecting three eye-drawings from Experiment 13. The hand eye-drawings have been lofted around their axis, transforming the eye-drawings into a 3D representation.
Figure 16 illustrates more lofted sculptural developments through the same logic.
These images deserve a pause of reflection in view of possible future experiments and further developments. The discourse surrounding results like Figure 15 and Figure 16 can initiate from the idea of what Manning (2007, p. 77) describes as events of perception, or ‘prehensions’. Manning speaks about Marey’s interest in creating machines and processes which do not strictly represent movement but bring into being new modalities of perception. It is this sense of unfamiliarity which leads to further experimentation, and in Murray’s case led him to actually commission a bronze representation of the bird in flight; emphasising the fact that he was not only concerned with a quantitative analysis of the movement of the wings (Manning, 2009, p. 99).
Even though my world is not Marey’s, and my perception of it varies greatly from his, I believe that the appropriation of the notion of creating ‘new modalities of perception’ as a leading factor for novel experimentation, is an important framework in view of these sculptural developments.
It is important not to view the eye-drawings as no more than data of recorded movements. They have to be acknowledged as perceptive moments in time and space belonging to a meaningful subject matter.
These developments can potentially highlight the historical relationship between drawing and sculpture; between projection and realisation. A certain degree of their execution can also be associated to generative art. The eye-drawings and decision making of how to arrange them in the virtual space is my doing, but the practice of lofting (or any other surface creation) is principally computer-assisted. Even though I am presented with several variable options regarding the latter (curve degree, rebuilding curves and curve direction among others), I can never be in total control (or anticipation) of the resulting representation. There will always be an element of surprise and a degree of trial and error in this practice, which I find stimulating.
More experimentation also raises the question of whether the sculptures should remain in the virtual environment (video, VR, AR, etc.) or be digitally fabricated (when possible).

4: Eye drawing the hand from different viewpoints

Figure 13: Three eye-drawings of the same rotating hand-gesture

After repeatedly eye-drawing my left hand from the same perspective, I tried eye-drawing my right hand from different points of view by rotating the same gesture (Figure 13 and Figure 14). The hand and drawing have a long history, and not just because of the manuality within the hand-eye coordination. The hand is the ‘skill’ and the means by which to ‘imprint’ while drawing, but it has also been regarded as one of the most difficult body parts to draw as a subject matter; not just for its anatomical rendition but also due to the cultural and symbolic values carried by its gestures. It has been therefore studied and drawn extensively (Petherbridge, 2010, pp. 251-259).
The hand carries innate verbal ways of communication, and it has been crucial in the evolutionary steps of our body, making us the humans of today (it allowed us the use of tools). The hand is also a sign of presence. Perhaps these are some of the reasons why it has been widely represented, from primitive art to contemporary times. Yet, in our daily routine we are barely aware of the hand.
It is worth mentioning that the hand has also been the vehicle with which to challenge the conventional ways of drawing (eg. automatism). While I am eye drawing, the hand is free as it is the body part which has been by-passed from the process. It is there and it can be eye-drawn. It is therefore very instinctive to do so.

3: Eye drawing the hand – part 2

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.
