Advances in haptic technologies can alter how real objects feel to our touch and create the experience of augmented reality (AR). However, definition, use cases, value end users such AR remain unclear. Existing work is concerned with technological implementation lacks a user-centered perspective. To address these limitations, we analyze systems literature understand what constitutes AR, why would want sense touch, interactions take place. demonstrate studying context real-world tasks user...

Abstract When applied to the skin, chemical stimulants can evoke haptic sensations. However, they need be continuously using paper or pads in fixed locations, limiting their usefulness as a general technology. To overcome these limitations, we introduce an ultrasound-based system for precise acoustophoresis of droplets skin. We show that such indeed produce distinct In addition, use ultrasound stimulate area skin where have been applied. this increases perceived intensity. Taken together,...

In this study, stability, density, rheology, and thermal conductivity of the Multi-wall carbon nanotubes (MWCNTs) based PCM nanocomposites were experimentally investigated. The OM08 has been selected for air-conditioning application with a phase change temperature 8–10 °C. (without surfactant) in various concentrations namely 0.05, 0.1, 0.3 0.5 vol. % prepared using typical two-step method high homogenous stability is achieved mechanical mixing technique (ultra-sonication). density was...

Augmented Reality (AR) excels at altering what we see but non-visual sensations are difficult to augment. To augment in AR, draw on the visual language of comic books. Synthesizing studies, create a design space describing how use elements (e.g., onomatopoeia) depict hearing). demonstrate this space, built eight demos, such as speed lines make user think they faster and smell scent seem stronger. We evaluate these qualitative study (N=20) where participants performed everyday tasks with...

Interactions using the face, not only enable multi-tasking but also us to create hands-free applications. Previous works in HCI used sensors attached directly person's face or inside their mouth. However, a mask, which has now become norm our everyday life and is socially acceptable, rarely been explore facial interactions. We designed, "DUMask", an interface that uses parts covered by mask discretely 14 (+1 default) DUMask infrared camera embedded off-the-shelf recognize gestures, we...

Virtual, Mixed, and Augmented Reality (XR) technologies hold immense potential for transforming productivity beyond PC. Therefore there is a critical need improved text input solutions XR. However, achieving efficient in these environments remains significant challenge. This paper examines the current landscape of XR techniques, focusing on importance keyboards (both physical virtual) as essential tools. We discuss unique challenges opportunities presented by XR, synthesizing key trends from...

Different form factors of wearable technology provide unique opportunities for output based on how they are connected to the human body. In this work, we investigate idea delivering notifications through devices worn underside a user’s clothing. A in such manner is direct contact with skin. We leverage proximity test performance 10 on-skin sensations (Press, Poke, Pinch, Heat, Cool, Blow, Suck, Vibrate, Moisture and Brush) as methods notification delivery. developed prototypes each stimulus...

From sports to party games, almost every kind of game has been adapted into a digital video format. While previous research studied player motivations and experiences for certain categories there yet be such study on board especially in the modern context smartphone apps. To address this, we conduct case popular game, Ludo, understand players' opinions its adaptation. For functionality user reviews nine Ludo apps, assess how traditional gameplay re-imagined. Based upon our analysis, conclude...

Robots increasingly interact with humans through touch, where people are touching or being touched by robots. Yet, little is known about how such interactions shape a user’s experience. To inform future work in this area, we conduct systematic review of 44 studies on physical human–robot interaction (pHRI). Our examines the parameters touch (e.g., role location), experimental variations used researchers, and methods to assess user We identify five facets experience metrics from questionnaire...

Ultrasound haptics allows us to experience the sense of touch without contact with any physical surface. This novel "touchless" feedback can be used for various use cases but is not widely adopted nor incorporated in everyday products. The 2022 TOUCHLESS Hackathon aimed enable practitioners learn about touchless technology, generate new ideas, and implement prototypes. We invited participants a 3-day hackathon Copenhagen, Denmark, where we introduced technology provided devices prototyping...

We present AICA, a speculative design project that imagines the use of AI to suggest person what say next during verbal conversation. It consists ring and pair spectacles which provide discreet input output capabilities mid-conversation along with an app for overall control over system. To such human-technology symbiosis, we employed three-pronged approach strike balance between all entities in conversation: user, being talked to.

In this paper, we explore input with wearables that can be attached and detached at will from any of our regular clothes. These do not cause permanent effect on clothing are suitable to worn anywhere, thus making them very similar badges wear. To idea non-permanent badge input, studied various methods fasten objects organise in the form a design space. We leverage synthesis, along literature existing products present possible interaction gestures these badge-based enable.

Abstract This research paper deals with the pollution impact of biomedical waste (BMW) generation due to COVID-19 pandemic, at both global and national levels. discussion is important in light clear scientific evidence that apart from airborne transmission disease, virus also survives on different surfaces carrying it risk infection. Moreover, an investigation conducted tons/day India during COVID period future projections are made. In addition, a pioneering study has been carried out...

The design principle of a basic pulse stretcher circuit is discussed and novel linear reported. salient feature the that simple inexpensive for linearity achieved.
