Introduction
Recently I came back to user modeling and user-adapted interaction. This is a renewed interest driven by ongoing work on the neurophysiological properties of vibrotactile displays. Interest is design theory and methodology lingers. And also lingers exploratory work on sound as an interaction modality.

Trust as a precursor for users' acceptance of artificial intelligence (AI) technologies that operate as a conceptual extension of humans (e.g., autonomous vehicles (AVs)) is highly influenced by users' risk perception amongst other factors. Prior studies that investigated the interplay between risk and trust perception recommended the development o...

Artificial intelligence (AI) systems are becoming pervasive in modern day society. Nonetheless, AI is not infallible. Therefore as more task and controls get delegated to AI systems, the implications become dire and riskier (e.g. Google assistant falling to make an emergency call hands-free), which impacts users experience and make users unforgivin...

New technologies, data, and algorithms impact nearly every aspect of daily life. Unfortunately, many of these algorithms operate like black boxes and cannot explain their results even to their programmers, let alone to end-users. As more and more tasks get delegated to such intelligent systems and the nature of user interactions with them becomes i...

Importance of touch cannot be underestimated. Touch is the first sense that a human develops already in a womb and the last sense that one loses with age. Touch can serve as a powerful modality for developing novel human-computer interfaces. We present VibroSquare - our first vibro-tactile display we designed to enable first set of experiments to t...
Chapter
Tactile feedback is a powerful modality for designing human-computer interfaces. Here we explore new ways of communication through tactile senses that can be perceived implicitly. This paper outlines the preliminary phase of research the goal of which is to investigate to what extent a vibro-tactile stimulus can be meaningfully communicated on an u...
