Animation and Choreography in the classroom

Posted on June 18th, 2013

The relationship between choreography and animation is symbiotic. Each time Norah and I collaborate across our disciplines, we reaffirm the desire to construct a course that explores both choreographic and animation approaches to movement, by integrating both dancers and animators. (I don’t know of any example of such a course existing in college curricula, but if you have knowledge about it – please send us a note.)

 

This Motion Bank project has inspired us to try an exercise in getting animators and dancers working together. Using our two co-scheduled Spring 2013 courses (Expressive Animation and Interdisciplinary Creative Research Seminar), we designed an experience for our animation and dance students that engaged them with Thomas Hauert’s Careful Scientist exercise.

 

We began by introducing the students to Thomas’s exercise by looking at a video of his performance.  In the Careful Scientist exercise, Hauert defines a limited set of instructions or rules for moving the body. He defines the rules of the system in such a way that they challenge mind/body habits.  In order for the students to better understand the work, concentration and coordination necessary for this exercise we had them practice some of the basic concepts by trying these movements in groups with others assisting.  Next we presented the students with some of the data of the Careful Scientist that we had motion captured during one of Thomas’s residencies at ACCAD. This provided a rich data resource of 3D positions and timings that describe the movement.  We then challenged the students to reuse existing motion captured movement data to re-imagine and design a new system of relationships, driven by existing movement data to become a new movement phenomenon. Three outcomes from that assignment follow,  accompanied by the students’ explanations.

 

Flowers by Maddy Varner and Daniel Diller


Concept: “We are using the data of an unnatural movement process and placing it on a natural environment. We are creating movement in the animation that is driven by external forces (like wind) while the careful scientist is propelled by internal choices. “

Tech Notes: “Upper Arm Pointing data occurs on the X and Z axes of the shoulder joint and is assigned to the direction of the flower stems movement (making them look like they’re being blown by the wind). Shoulder Rotation data occurs on the Y-axis of the shoulder joint and is assigned to the wilting and blossoming of the flower heads. Elbow Flexion data occurs on the Z and X axes of the elbow joint and is assigned to the growth of the flowers. Forearm Rotation data occurs on the Y-axis of the elbow joint and controls the color of the flowers. “

 

Spork! by Jonathan Welch


Concept: “I used a motion capture of the Careful Scientist by Thomas Hauert to create a visual parody on the hybrid theme prevalent in art and technology work. All the motion is a combination of the Careful Scientist, at different speeds and directions, with altered key frames to influence the gestures and correct for problems translating a human’s motion to the altered anatomy of the characters. The combined motion is intended to be dis-articulated, awkward, and hyper extended; alluding to a dysfunctional parental couple whose behavior is compounded through their child. “
Tech notes: “To start, I sped up the motion capture data, duplicated it, translated it forward, and attached both to the spoon. Then I duplicated the motion again, and broke it down into key frames in places where the hand went through the head and moments that I decided to make the existing gestures more like an argument. I wanted the fork to have a slightly different personality, so I took the key frame motion path, duplicated it, reversed it and attached the motion to the fork. The spork’s motion is the same as the spoon, without the argument key frames, and not quite as fast. “

 

Ontology of Thomas Hauert’s ‘Careful Scientist‘: Judith Butler’s reading of Derridean “Citationality” by Carolin Scheler and Kaustavi Sarkar


Concept:  “Dance scholar Susan Leigh Foster describes improvisation in dance as ‘bodyful’ dwelling in the perceptual gap of the conscious and the unconscious. Continuing the quest of the unknown through digital inscription of dance, we argue that digital ontology exists in corporeal materiality of the performing body as performatively, affectively and digitally mediated in the animation of Hauert’s Careful Scientist. Through Butler’s reading of ‘citationality’, in which ‘matter is constructed not as a site but as a process of materialization that stabilizes over time to produce the effect of boundary, fixity, and surface we call matter’, the digital is ontologized in Hauert’s performativity.”

ACCAD animation specialist and motion capture expert Vita Berezina-Blackburn has continuously pushed our Center in thinking about unconventional ways to use captured motion. As an animation artist and collaborator on Bebe Miller’s Landing Place her work demonstrated the aesthetic beauty that can result from expertly combining captured motion and form. Take a look at some of Vita’s work from Landing Place.

Permutations

Posted on June 17th, 2013

The Careful Scientist exercise requires following a small set of joint movement rules which dictate the ways a performer’s arms may move.  As part of the rule set no movement that is happening on the one side of the body can happen at the same time on the other side of the body.  Because the options are so discrete and constrained, the number of possible action sequences can be calculated.   As we have discussed here previously, the movements are limited to: Upper Arm Pointing Shoulder Rotation Elbow Flexion Forearm Rotation With a new action being chosen roughly every 1-3 seconds, there are millions of possible sequences for the first half minute of the exercise. Calculating the number of permutations was useful for giving a…

Careful Scientist Choice and Timing Analysis

Posted on June 16th, 2013

In an effort to make visible the choices that each performer makes in performing the Careful Scientist exercise, we devised a motion capture analysis algorithm to track data captured in different performers execution of the Careful Scientist.   OSU graduate research assistant J. Eisenmann designed the algorithm which is run on the motion capture files and identifies which action is happening on which arm and over what amount of time (in frames).   An example of the data list that the algorithm generates from one of Thomas Hauert’s motion captured performances of the exercise:   Who   Frame, Action,    L/R side ———————————— Thomas,1591,3_ElbowFlex,L, Thomas,1645,1_UpperArmPointing,R, Thomas,1877,4_ForearmRotation,L, Thomas,2086,3_ElbowFlex,R, Thomas,2262,1_UpperArmPointing,L, Thomas,2470,2_ShoulderRotation,R, Thomas,2766,4_ForearmRotation,L, Thomas,2955,3_ElbowFlex,R, Thomas,3154,1_UpperArmPointing,L, Thomas,3478,4_ForearmRotation,L, Thomas,3533,1_UpperArmPointing,R, Thomas,3751,3_ElbowFlex,L, Thomas,4007,3_ElbowFlex,R, Thomas,4190,4_ForearmRotation,L,   After the algorithm generates the data list, we then…
