Abstract

Within Human-Computer Interaction, there has recently been an important turn to embodied and voice-based interaction. In this chapter, we discuss our ongoing research on building online Embodied Conversational Agents (ECAs), specifically, their interactive 3D web graphics aspects. We present ECAs based on our technological pipeline, which integrates a number of free online editors, such as Adobe Fuse CC or MakeHuman, and standards, mainly BML (Behaviour Markup Language). We claim that making embodiment available for online ECAs is attainable, and advantageous over current alternatives, mostly desktop-based. In this chapter we also report on initial results of activities aimed to explore the physical appearance of ECAs for older people. A group of them (N = 14) designed female ECAs. Designing them was easy and great fun. The perspective on older-adult HCI introduced in this chapter is mostly technological, allowing for rapid online experimentations to address key issues, such as anthropomorphic aspects, in the design of ECAs with, and for, older people.
