“…While limited in the dynamic range of intensities, they can be used to generate tactile feed back on objects independent of whether the finger is moving or stationary [18,23]. Furthermore, recent research shows that electro-tactile interfaces can be easily fabricated using print ing [21] and can be realized as thin and flexible interfaces [56]. However, neither a systematic approach to identify the pos sible tactile renderings on physical objects nor a method to easily augment physical objects with electro-tactile interfaces has been studied.…”

“…To fabricate the interactive object, the design tool generates a printable low-level electrode layout of the electro-tactile interface. The generated design is then printed using one of two alternatives: For rapid fabrication within minutes, con ductive inkjet printing [21,22] can be used to print a thin, flexible electro-tactile overlay to be attached to the object. Al ternatively, the interactive object can be 3D printed using a commodity FDM 3D printer and conductive filament, realiz ing the object with the embedded electro-tactile interface in a single pass.…”

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

“…This principle has been investigated and its functioning has been extensively confirmed through psychophysical studies [9,33,21,54]. Electro-tactile interfaces have been demonstrated for various areas of the body, such as the fingertips [34,4,39,30,21,59,36], forearm [21,51,14], abdomen [29,60], back [9] and tongue [4,61].…”

“…It contains a dense array of electro-tactile taxels at a density comparable with the electro-tactile acuity of skin. With less than 35 µm thickness, Tacttoo is the thinnest tactile interface presented in the literature (by a factor of 3 compared to work in materials [51,14] and a factor of 8 compared to recent work in HCI [36]). Tacttoo's thin and flexible form factor allows the interface to be conformal with the skin and for the first time enables feel-through tactile output.…”

Haptic feedback, a natural component of our everyday interactions in the physical world, requires careful design in virtual environments. However, feedback location can vary from the fingertip to the finger, hand, and arm due to heterogeneous input/output technology used for virtual environments, from joysticks to controllers, gloves, armbands, and vests. In this work, we report on the user experience of touch interaction with virtual displays when vibrotactile feedback is delivered on the finger, wrist, and forearm. In a first controlled experiment with fourteen participants and virtual displays rendered through a head-mounted device, we report a user experience characterized by high perceived enjoyment, confidence, efficiency, and integration as well as low perceived distraction, difficulty, and confusion. Moreover, we highlight participants’ preferences for vibrotactile feedback on the finger compared to other locations on the arm or through the VR controller, respectively. In a follow-up experiment with fourteen new participants and physical touchscreens, we report a similar preference for the finger, but also specific nuances of the self-reported experience, not observed in the first experiment with virtual displays. Overall, our results depict an enhanced user experience when distal vibrotactile feedback is available over no vibrations at all during interactions with virtual and physical displays, for which we propose future work opportunities for augmented interactions in virtual worlds.
