“…Embedding haptic or tactile feedback in objects has been widely used to increase the user experience and interaction ca pabilities of mobile and physical computing devices [27]. For example, haptic feedback is utilized to offer physical feedback for visual controls [12,30,38,58,59,61] and icons [2,26], for rendering virtual textures and geometric features [1,24,40] and to implement shape-changing displays [7,57].…”

“…For instance, shape-changing displays make use of embedded mechanical [7,15], pneumatic [51] or mag netic [28] actuators, or the object itself is built from shapechanging materials [57]. Similarly, tactile interfaces have been realized by embedding actuators in the device [12,30,38,59,61]. This approach often suffers from low-resolution output.…”

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

“…We conduct an experiment to evaluate the effect of physical challenging activities on user perception of tactile textures. We consider five challenging activities that represent common situations where users often use their smartphones: (1) seated in an office [4], (2) standing in an office [11], (3) seated in the tramway [5], (4) standing in the tramway [10] and (5) walking in the street [24,27].…”

Pielot et al [27] used vibrotactile feedback on a touchscreen device for an optimized eyes-free menu, and showed that, while walking, the improved menu with tactile feedback surpassed a replica of the iPhone's VoiceOver.

Meanwhile, touch devices are widely used in physical challenging activities (e.g., standing [11], being in the tramway either standing [10] or seated [5] or walking in the street [7,18,24,27]), which makes environmental demands, visual loads and mental resources another parameters to take into account when designing touch devices.

Previous research demonstrated the ability for users to accurately recognize tactile textures on mobile surface. However, the experiments were only run in a lab setting and the ability for users to recognize tactile texture in a real-world environment remains unclear. In this paper, we investigate the effects of physical challenging activities on tactile textures recognition. We consider five conditions: (1) seated on an office, (2) standing in an office, (3) seated in the tramway, (4) standing in the tramway and (5) walking in the street. Our findings indicate that when walking, performances deteriorated compared to the remainder conditions. However, despite this deterioration, the recognition rate stay higher than 82% suggesting that tactile texture could be effectively recognized and used by users in different physical challenges activities including walking.

The popular outdoor pursuit of backpacking is profoundly changing as the community embraces contemporary information technologies. However, there is little empirical evidence on the adoption and use of consumer electronics by backpackers, nor the implications this has for their habits, practices, and interactions. We investigate long‐distance backpackers' articulations with mobile information technology during the TGO Challenge, a coast‐to‐coast crossing of the Scottish Highlands. By employing mixed methods, we explore how and why backpackers use such technology when planning and undertaking their journeys via a survey (n = 116), pre‐ and post‐challenge interviews with selected TGO participants, and daily in‐field video‐logs. Our results suggest many advantages to using technology in this context, including fluidity of communications and access, while noting that reliance on technology is leading to issues such as increased need for battery power management, and deskilling. The findings highlight implications for the juxtaposition between outdoor recreation, information behavior, and human computer interaction (HCI) and suggest future work in this area.
