“…User interfaces based on object levitation are one realisation of Ishii's radical atoms vision [10], a vision of physical materials that can change form and appearance dynamically, to allow new and richer ways of interacting with information. Small levitating objects can be the 'atoms' from which physical objects are composed; these composite objects exist in mid-air and can change form dynamically, by rearranging the 'atoms'.…”

Acoustic levitation enables a radical new type of humancomputer interface composed of small levitating objects. For the first time, we investigate the selection of such objects, an important part of interaction with a levitating object display. We present Point-and-Shake, a mid-air pointing interaction for selecting levitating objects, with feedback given through object movement. We describe the implementation of this technique and present two user studies that evaluate it. The first study found that users could accurately (96%) and quickly (4.1s) select objects by pointing at them. The second study found that users were able to accurately (95%) and quickly (3s) select occluded objects. These results show that Pointand-Shake is an effective way of initiating interaction with levitating object displays.

“…Hiroshi Ishii's vision of Radical Atoms [25] is popular within tangible user interface research, and describes hypothetical reconfigurable materials described by real-time digital models such that changes in digital information can be reflected by a corresponding change in physical state and vice-versa. We consider Bioty as a substantial step towards making these visions a reality in the life sciences.…”

Life-science research is increasingly accelerated through instrumentation advancements -even supporting the real-time interaction with living matter in the cloud. This enables entirely new applications for research, education, and art. The creation of such applications is currently challenging and time consuming, even for experts, as it requires knowledge of biotechnology, hardware design, and software development in addition to continuous access to reliable and responsive biological materials. We therefore developed Bioty, a JavaScript-based web toolkit enabling rapid prototyping of versatile Human-Biology Interaction (HBI) applications utilizing swarms of motile, phototactic cells hosted on a remote cloud lab. We evaluated and demonstrated the utility of Bioty through user studies with both HBI novices and experts, who used Bioty to create applications such as interactive scientific experiments, biotic video games, and biological art. Our findings inform the design of development toolkits for programming the behavior of biological matter.

“…The concept of "programmable matter" is a long-term aspiration for many researchers in the robotic and display domains [37,8,15]. This vision comprises the possibility of programmatically controlling physical objects, allowing them to change their visual appearance, physical shape and provide on-demand functionality, both replicating and surpassing the functionality of current digital displays.…”

Figure 1. Programmable liquid matter making nonlinear shape of alphabet "S". 7x7 electrodes array dynamic switching to control EGaIn to make an 'S' shape. ABSTRACTIn this paper, we demonstrate a method for the dynamic 2D transformation of liquid matter and present unique organic animations based on spatio-temporally controlled electric fields.In particular, we deploy a droplet of liquid metal (Gallium indium eutectic alloy) in a 7x7 electrode array prototype system, featuring an integrated image tracking system and a simple GUI. Exploiting the strong dependance of EGaIn's surface tension on external electric voltages, we control multiple electrodes dynamically to manipulate the liquid metal into a fine-grained desired shape. Taking advantage of the high conductivity of liquid metals, we introduce a shape changing, reconfigurable smart circuit as an example of unique applications. We discuss system constraints and the overarching challenge of controlling liquid metals in the presence of phenomena such as splitting, self-electrode interference and finger instabilities. Finally, we reflect on the broader vision of this project and discuss our work in the context of the wider scope of programmable materials.
