魅力的とカワイイ
Cute & Kawaii
Cuteness triggers an innate socioaffective response in virtually all people. Our research focuses on the Japanese cultural instantiation of cuteness, a cultural export that features in products from video games to virtual companions to social robots to AI toys. One trajectory is the science of kawaii vocalics, created by Dr. Seaborn, where we research the properties and effects of kawaii voice phenomena. Kawaii embodiments can affect first impressions, trust, rapport, and compatibility and potentially charm and disarm users unaware. We explore emotional responses and behaviour with cute and kawaii computer offerings.

Kawaii Computing
Kawaii computing is a field of study that explores the Japanese concept of cute in interactive experiences with computers, within and outside of Japan.

Modelling Kawaii Vocalics
Little is known about kawaii as a sound phenomenon. Do features of visual kawaii transfer? What unique properties do kawaii voices have? We ask foundational questions to develop a a model of kawaii vocalics.
音の現象としてのカワイイについてはほとんど知られていない。視覚的なカワイイにはどのような特徴があるのか?カワイイ音声にはどんなユニークな特性があるのか?我々は問う。

Kawaii Voice & Body
Is kawaii perceived the same way in voice and body? We explore whether and how the two differ and intersect through a variety of voices and characters.

Cute & Deceptive
Charming and disarming: when characters are cute, we may be influenced to unknown ends, unawares. We critically examine the deceptive potentials of cute and kawaii computer agents, social robots, and AI toys.

音声UX
Voice & Embodiment
Voice is a natural mode of communication, used to deliver information (speech) and express characteristics of the speaker (vocalics). Advances in audio signal processing and machine learning have pushed voice user experiences (voice UX) to the forefront of modern human-computer interactions. We explore the paradigm of voice UX and its embodiments through systematic reviews, critical design studies, and controlled experiments.

Voice Against Bias
Can voice influence attitudes towards age? We aim to find out with MAKOTO, our “older adult” voice assistant.

Culturally Sensitive Voice UX
Voice is a powerful mode of communication among people and with computers. Yet, we must consider the sociocultural and linguistic contexts. One person's "eh?" is another person's "ne~"!

Gender Ambiguity in Computer Voices
We explore the notion of gender ambiguity as a way of understanding how different people gender (or not gender) computer voices.

Vocal Sycophancy
Sycophancy in conversational agents, like chatbots, has almost entirely focused on the text medium. Does voice-based sycophancy exist? Is it equally affirmative, flattering, and excessively agreeable?
Selected Publications
アイデンティティと権力
Identity & Power
Identity and power operate through design practice and objects with respect to overlapping factors of social identity, such as gender, age, and race. Designers, knowingly or not, draw on social models of how we look and sound, think and behave, and interact with the world. Users, too, respond in kind. We approach this phenomenon from an intersectional perspective, focusing on whether human diversity is reflected in design and research practice as well as how user reactions are shaped by biases embedded in the design of intelligent agents and interactive experiences.

Gender Neutrality in AI
We critically examine whether and how virtual AI (like chatbots) and embodied AI (like robots) can be designed and perceived as gender-neutral.

Evaluating Gender Perceptions
What is "gender," what does it mean "to gender," and how do we capture this "gendering" in a standard and understandable way? We aim to develop standards, measures, and methods.
Selected Publications

Meta-Level Biases
Bias does not only exist in the minds of participants and within the code of machines—it also acts within professionals and practice. We critically examine biases on the "expert side."

Agender Euphoria in Play
Agender euphoria is the experience of self-fulfillment, freedom, and bliss in gender-free environments, embodiments, and interactions. We define and explore this experiential phenomenon.

批判的なプレー
Critical Play
Play and games are foundational elements of human societies and personal development, from childhood onwards. Simulations, digital play, and video games draw in people of all ages, for all kinds of motivations. Games offer a space where the rules of reality can be suspended. We critically explore and entertain new forms of engagement within and orientations towards interactive play and games.

Maldaimonic Game UX
Maldaimonic player orientations and experiences are all about having fun being bad without harming others.

ネガバースに潜む危険性
Decoding the Negaverse
Are we living in a negaverse? Critical scholarship has drawn attention to a range of ways in which technology exploits, affords, or even celebrates negative experiences. Deceptive patterns and persuasive interfaces, misinformation and fake news, and even gamified offerings can have adverse effects, intentionally or not. We explore how negative user experiences and orientations play out across a range of interactive systems, as well as how they can be disrupted.

Deceptive Patterns in Japan
We carry out culturally-sensitive research on deceptive patterns or ダークパターン in Japan, covering a range of e-commerce contexts.

信頼と依存
Trust & Reliance
Trust is the foundation of fulfilling human-human connections. Interactive and agentic technologies, like chatbots, AI toys, and social robots, portray humanlike personas, embodiments, and interactions that may elicit distrust, cultivate overtrust, or facilitate reliance. We critically examine the matter of trust in modern-day interactive computing.

Trust in AI
What factors affect trust and reliance in AI-based agents, systems, and environments? Exploring layperson and expert perspectives.
AIを活用したエージェント、システム、環境に対する信頼や信用に影響を与える要因とは?一般人や専門家の視点を探ります。

Time & Trust
A lot of research on interactive agents and AI focuses on short-term engagements. However, realistic use with implications for trust and reliance is often longitudinal.

体制を揺るがす抵抗
Subversive Dissent
Design is a powerful means of creating change in the world. Often, the same material and strategies can be deployed for purposes empowering or disempowering, altruistic or self-serving, capitalistic or collectivist. In these projects, we unearth and subvert power structures and unwelcome norms through critique and (re)design.

User-Led (Re)Design
Experts prescribe the user experience and presume usability, with perhaps some user involvement or user testing. Instead, we explore power-shifting participatory action, co-design, and user-led design practice.

Disrupting Generative AI
Generative AI and its purveyors have infiltrated everyday life, including knowledge production, creative processes, personal rights and sensibilities, and common speech. We explore critical interventions against Generative AI dominance and misuse.

日常的なインターフェイスにおける ダーク・パターンの発見と解体
Discovering and Dismantling Dark Patterns in Everyday Interfaces
Online manipulation and interface deception are pressing, global threats to everyday users of the Internet. At the user interface (UI) level are tricky and coercive interactive elements found in everyday digital products, variably known as "dark patterns," deceptive designs, and manipulative UI. As a PRESTO・さきがけ fellow, I aimed to untangle the nature of such forms of interface deception in Japan, discover how are they perceived by professionals and the public, and explore how they can be redressed.

Kawaii Vocalics
This project will focus on the novel concept of kawaii vocalics. The two research trajectories are: (i) what is the nature of kawaii vocalics compared to kawaii visuals, which comprises almost all work on kawaii science so far (theoretical extension); and (ii) what emotions and behaviour do kawaii voices elicit compared to kawaii visuals (methodological extension).

ロボットの芳香
Aromanoidics
We explored people's mental models of robot scent: imagined and real. To this end, we conducted exploratory human participant research on scent-to-robot matching and controlled experiments of different scents for different robots. We aimed to spark research on robot aroma and olfactory interaction. The results may be used in the design of robots that work closely with people, such as in the workplace, in the home, as (aroma)therapeutic robots, and in customer service settings, especially at storefronts.

偏見に対抗する音声
Voice Against Bias
We explored the use of a virtual assistant with the voice of an older adult as a novel method of reducing implicit ageism. Such cognitive biases, as natural functions of the human mind, are influenced by the external world in positive and negative ways. Through co-design methodologies, intergenerational user studies, and long-term "in the wild" evaluations, we examined whether voice assistant "elders" could shift biases in a prosocial direction.
