Early concept validation through provocative experience prototyping

This essay reports on a research project aiming at validation of a concept for an Al-driven speech interface for smart services in public spaces. The research team created a simple experience prototype that simulated the envisioned functionality and was used to experiment with subjects in dialogues. The interaction with the prototype invoked a provocative experience that allowed test subjects to better imagine the impact that such a concept for smart services would have in their neighbourhood.

Using Lo-Fi prototyping to envision conversational agents in public settings

Speech interactions are often associated with virtual assistants and smart home devices, designed primarily for private contexts. A less developed domain is speech interfaces in public contexts. In a smart city development project, we explored the potential of distributed conversational speech interfaces in lampposts. Deploying a research-through-design method, we created a lo-fi prototype of the speech interface that test subjects could interact with during experiments in a lab setting. Our first exploratory prototype consisted of a loudspeaker that acted as the interface and preconceived dialogues designed to investigate the boundaries of desirable and acceptable experiences regarding issues such as privacy. Experiencing the interaction with this rudimentary prototype helped people envision potential use cases and reflect on privacy issues: the dialogues revealed subjective limits of what kind of (personal) information people were willing to share with the lamppost. They also elicited thoughts on possible consequences in the social context of citizens. LinkedIn: https://www.linkedin.com/in/atjylha/ https://www.linkedin.com/in/josvanleeuwen/

Envisioning conversational agents in public spaces

Beyond the potential of new layers of urban infrastructure - sensor-laden networks, big data, artificial intelligence - to optimize cities functionally, lay promising opportunities to also use these technologies for new forms of social interactions. In an ongoing smart city development project, we explore the potential of distributed conversational speech interfaces in the social context of local urban communities.

Using Lo-Fi experience prototypes for co-designing conversational speech interactions for public settings

In an on-going smart city development project, we are exploring the potential of distributed conversational speech interfaces in the public context of a city. By using the well-known Wizard of Oz method in combination with a lo-fi prototype, we involve participants in co-design with the focus on potential use cases, social acceptability, and privacy aspects of interacting with a speech interface publicly. The work taps into the gap of design-oriented work in the domain of speech-based HCI. LinkedIn: https://www.linkedin.com/in/atjylha/ https://www.linkedin.com/in/josvanleeuwen/
