    Transhuman Expression - Human-Machine Interaction as a Neutral Base for a New Artistic and Creative Practice
    (The Eurographics Association, 2019) Grayver, Liat; Volpe, Gualtiero; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    Transhuman Expression is an interactive room installation created by Liat Grayver in collaboration with the EU-H2020-ICT project weDRAW in the context of a Vertigo STARTS residency at the Casa Paganini - InfoMus reseach center of DIBRIS - University of Genova, Italy. Data captured via motion detection of visitors is analyzed, processed, and projected on large screens positioned in the exhibition area. The collaboration benefited, was built on, and furthered experiences that both the artist and the research team have had in ongoing work exploring convergence of artistic and scientific practices. Grayver's work in robotics-assisted painting gained new tools that can be integrated into the system she works with at the University of Konstanz, whilst Casa Paganini - InfoMus has acquired new perspectives on the range, scope, and scale of real-time, automated movement analysis. This paper reports about goals, methodology, and results of such a joint multidisciplinary activity.

    Mutator VR: Vortex Artwork and Science Pedagogy Adaptations
    (The Eurographics Association, 2019) Putnam, Lance; Todd, Stephen; Latham, William; Williams, Duncan; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    We present our virtual reality artwork Mutator VR: Vortex that immerses the viewer in procedurally-generated alien environments inhabited by interactive ''mutoid'' agents. The artwork was adapted into two science pedagogy experiences. Techniques and considerations regarding the dynamical, spatial, and graphical composition of the experiences are provided.

    SURFACE: Xbox Controlled Hot-wire Foam Cutter
    (The Eurographics Association, 2019) Hong, Freddie Taewoo; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    This artwork is a 3-axis sculpting instrument controlled by an Xbox controller, which allows anyone to intuitively apply one's creativity in a real-time flow without the aid of pre-drawn digital geometry. Surface runs purely on user instinct rather than on any digital geometry. The artwork explores the ambiguous boundary between the analogue and digital; it also challenges conventional methods of digital fabrication, which rely vitally on CAD software.

    The CyberAnthill: A Computational Sculpture
    (The Eurographics Association, 2019) Raskob, Evan; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    The CyberAnthill is both a generative sculpture and a Live Computational Sculpting (LCS) system that uses a 3D printer and custom software to build plastic sculptures out of layered cellular automata. As the title alludes to, the cellular automata are inspired by Langston's Ant and the light cycle racers in the cult 1980's science-fiction movie Tron. Instead of the normal process of printing exacting, predetermined 3D models, the 3D printer generates its plastic forms by running unpredictable computer code.

    Visual Communication with Successive Reading of Public and Secret Information by Generating Dual-Layer Images
    (The Eurographics Association, 2019) Hammoudi, Karim; Benhabiles, Halim; Melkemi, Mahmoud; Kadapanatham, Shashank Rao; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    In visual communication, visual cryptography is a technique that permits to share secret information through a two-step process. In a common processing scheme, two key images (ciphered images) are generated from a binary secret image. Then, the generated key images are sent to a recipient via two different communication channels. Once key images collected, the secret information is decoded via the human vision system by observing the superposition of the two key images. In this context, each key image generally has its appearance as a mix of black and white pixels. In this paper, we present a technique that permits to personalize the appearance of generated key images by making them exploitable for displaying visible information (e.g.; textual information) while simultaneously embedding secret information. A family of dual-layer images is thus highlighted towards fostering the development of visual creations. Experimental results show visual applications with successive reading of public and secret information from generated Dual-Layer key images.

    Artistic Sketching for Expressive Coding
    (The Eurographics Association, 2019) Fourquet, Elodie; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    This experiential paper describes using computer graphics and animation to motivate students taking their first programming course. An artistic context encourages students to create expressive images and animations. Their creative work consists in first abstracting a piece of art as a paper sketch, which they then abstract into code. Assessing the artistic merit of this activity will help our research community quest to better understand aesthetic, perception and meaning of visual representations [DS10].

    Emergence in the Expressive Machine
    (The Eurographics Association, 2019) Dekker, Laura; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    The ''Expressive Machine'' is a series of interactive artworks which explore a machine's-eye view of the world. The machine- an assemblage of hardware and software-provokes sensual interaction with viewer-participants, playing with transduction across multiple modes: from touch to sound, to word, to vision, to taste, to uniquely machinic states with no particular human analogue. These stimuli are processed in various interpretations, elaborations, in a relatively unstructured ''data soup''. Asynchronous processes consume data from the soup. When trigger conditions for a particular expressive process are satisfied, the machine produces externalised outputs in various forms: sound, shift of attention, fragments of narrative, and so on. What can be considered as creativity arises as an emergent property-a serendipitous by-product of the machine working through its experiences, rather than an explicit creative process. To make this conceptual exploration possible, an adaptable, extensible, decentralised system is presented: its requirements, architecture and some implementations as interactive artworks. Each new site and context gives rise to a unique instantiation of the machine, as it explores and expresses its experiences.

    Sketch-Based Modeling of Parametric Shapes
    (The Eurographics Association, 2019) Wailly, Bastien; Bousseau, Adrien; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    We demonstrate a sketch-based modeling system running on a multi-touch pen tablet. Our system takes inspiration from the work of Nishida et al. [NGDGA*16], who proposed to use deep convolutional networks to interpret sketches of parametric shapes. While Nishida et al. applied this approach to the creation of procedural buildings, we focus on the creation of simple shapes (cuboids, cylinders, cones, spheres, pyramids) that users can assemble to create more complex objects. In this poster we describe the main components of our system - the deep convolutional networks used for sketch interpretation, the training data, the user interface, and the overall software architecture that combines these components. We will allow conference attendees to test our system on a pen tablet.

    Wandering Without Wondering
    (The Eurographics Association, 2019) Williams, Peter J.; Wong, Sala; Berio, Daniel and Cruz, Pedro and Echevarria, Jose
    Wandering Without Wondering is a hybrid-media installation distilling and chronicling artists Sala Wong and Peter Williams' collaborative walking practice. The project uses various digital technologies to augment human senses, metaphorically linking and complicating the concepts of immersion and interaction through disruptive and hypermediated approaches to technologies such as 360-degree imaging, projection mapping, virtual reality and spatial audio produce an expressive, visually-saturated, physical/virtual hybrid space through which visitors journey between states of technologically-facilitated expression.
