Results

Below we present a gallery of all artifacts produced by the artists in our study.

• Task 1 - Draw a portrait
• Task 2 - Draw an imaginary machine
• Task 3 - Draw a sofa in a similar style

Viewing Notes

We present artist drawings (left) alongside a layout/snapshot showing how they organized their reference imagery and reference regions in the context of their desktop (right). The faint rectangles in the drawings represent where the artist placed their reference regions – areas which, when entered with their stylys, automatically present reference imagery. Orange rectangles represent global regions; these are regions that, when entered, present all of the reference images associated with the canvas.

If an image has no regions/reference, it is likely that the artist deleted them before they completed their task, as these snapshots only capture the final state of the artist's layout when completing their task.

Task 1: Draw a portrait

Artists were tasked to draw a portrait using our technology probe. Artists were provided a set of reference images of the subject and were asked to match the likeness of the subject as closely as possible in their drawing. The suggested task time was ~15mins. This task would sit on the detail recreation end of the Spectrum of Reference (see our paper for more information).

Task 2: Draw an imaginary machine

Artists were tasked to draw a (fictional) imaginary machine using our technology probe. This task sits somewhere on the middle of the Spectrum of Reference, where detail recreation and subject interpretation are common.

Task 3: Draw a sofa in a similar style

Artists were tasked to draw a sofa in the same style as the provided reference imaginary. This task sits on the interpretive end of the Spectrum of Reference.
