“…Design tools enable a high-level digital design process that abstracts from low-level fabrication parameters. Tools have been contributed for various application areas: designing ob jects with desired haptic properties [50], designing mecha nisms [13], designing electronics circuits [39], or designing interactive 3D objects [25,32,34,44,43,45]. While several approaches support designing custom touch sensors [25,32,34,45], the design of tactile output has so far been limited to low resolution, e.g.…”

edge slider buttons Tactlet library real-time control a b c d Figure 1. Tactlets is a novel approach enabling digital design and rapid printing of custom, high-resolution controls for tactile output with integrated touch sensing on interactive objects. (a) A design tool allows a designer to add Tactlet controls from a library and customize them for 3D object geometries. The designer can then fabricate a functional prototype using conductive inkjet printing (b) or 3D printing (c), and explore the interactive behavior of the Tactlet control. (d) This approach allows for rapid design iterations to prototype tactile input and output on a variety of objects. ABSTRACTRapid prototyping of haptic output on 3D objects promises to enable a more widespread use of the tactile channel for ubiqui tous, tangible, and wearable computing. Existing prototyping approaches, however, have limited tactile output capabilities, require advanced skills for design and fabrication, or are in compatible with curved object geometries. In this paper, we present a novel digital fabrication approach for printing cus tom, high-resolution controls for electro-tactile output with integrated touch sensing on interactive objects. It supports curved geometries of everyday objects. We contribute a de sign tool for modeling, testing, and refining tactile input and output at a high level of abstraction, based on parameterized electro-tactile controls. We further contribute an inventory of 10 parametric Tactlet controls that integrate sensing of user input with real-time electro-tactile feedback. We present two approaches for printing Tactlets on 3D objects, using conduc tive inkjet printing or FDM 3D printing. Empirical results from a psychophysical study and findings from two practi cal application cases confirm the functionality and practical feasibility of the Tactlets approach.•Human-centered computing → Human computer inter action (HCI); Haptic devices; Interactive systems and tools; Interface design prototyping;Digital fabrication has been proposed as a new method for rapid prototyping of interactive devices [10,25,34,32,44]. By printing the custom device, rather than manually assembling it from conventional electronic components, the fabrication process can be considerably simplified and sped up. At the same time, as printable electronics commonly are very thin and deformable, more demanding geometries and advanced I/O capabilities can be realized. Prior work has demonstrated ap proaches based on printed electronics to equip custom-shaped 3D objects with various types of printed sensors for capturing user input [11,34,44,45,54] and printable output compo nents, including light-emitting displays [35,54] and actuators for shape-change [7,57].However, tactile output was so far left unaddressed. Fab ricating custom interactive objects that include computercontrolled tactile output still relies on manually assembling conventional components [15,36]. Moreover, the rather large

“…For example, the crust of a planet is distinguished from its core; or the cell membrane from its nucleus. Digital fabrication techniques allow representation of structural information, through distinct internal and external material properties (Torres et al, 2015). However, 3D printed probes allow only surface exploration or deformation.…”

We explored the potential of haptics for improving science communication, and recognized that mid-air haptic interaction supports public engagement with science in three relevant themes. While science instruction often focuses on the cognitive domain of acquiring new knowledge, in science communication the primary goal is to produce personal responses, such as awareness, enjoyment, or interest in science. Science communicators seek novel ways of communicating with the public, often using new technologies to produce personal responses. Thus, we explored how mid-air haptics technology could play a role in communicating scientific concepts. We prototyped six mid-air haptic probes for three thematic areas: particle physics, quantum mechanics, cell biology; and conducted three qualitative focus group sessions with domain expert science communicators. Participants highlighted values of the dynamic features of mid-air haptics, its ability to produce shared experiences, and its flexibility in communicating scientific concepts through metaphors and stories. We discuss how mid-air haptics can complement existing approaches of science communication, for example multimedia experiences or live exhibits by helping to create enjoyment or interest, generalized to any fields of science.

“…Adding different passive haptic textures on different sides, such as patterns of bumps or ridges, would also increase available landmarks. Other related ideas include controlling the centre of mass to create a heavy end or side, and making some edges more pliable than others [23]. Diverse tactile patterns and asymmetries may also enable more reliable eyes-free usage and reduce error rate.…”

We examine two key human performance characteristics of a pen-like tangible input device that executes a different command depending on which corner, edge, or side contacts a surface. The manipulation time when transitioning between contacts is examined using physical mock-ups of three representative device sizes and a baseline pen mock-up. Results show the largest device is fastest overall and minimal differences with a pen for equivalent transitions. Using a hardware prototype able to sense all 26 different contacts, a second experiment evaluates learning and recall. Results show almost all 26 contacts can be learned in a two-hour session with an average of 94% recall after 24 hours. The results provide empirical evidence for the practicality, design, and utility for this type of tangible pen-like input.
