智能显示器增强了带有触摸屏的智能家庭扬声器的概念。虽然在该设备变体中添加了视觉模态,但虚拟代理仍然仅通过听觉输出表示,并且在大多数当前产品中仍然不可见。我们提出了一个实证研究的互动与智能显示器上的代理体现与人形表示的用户。三种不同的条件进行比较组间实验:没有代理的实施例,数字渲染的字符,和由人类女演员执行的照片级逼真的表示。我们的定量数据并不表明智能显示器上的代理可视化会显著影响用户体验。另一方面,我们的定性研究结果揭示了用户的不同观点。我们讨论的潜力和挑战,体现智能显示器上的代理,反映他们的持续在屏幕上的存在,目前用户的考虑,他们的外观,以及如何可视化影响用户的礼貌。
Smart displays augment the concept of a smart home speaker with a touchscreen. Although the visual modality is added in this device variant, the virtual agent is still only represented through auditory output and remains invisible in most current products. We present an empirical study on the interaction of users with a smart display on which the agent is embodied with a humanoid representation. Three different conditions are compared in a between-group experiment: no agent embodiment, a digitally rendered character, and a photorealistic representation performed by a human actress. Our quantitative data do not indicate that agent visualization on a smart display affects the user experience significantly. On the other hand, our qualitative findings revealed differentiated perspectives by the users. We discuss potentials and challenges of embodying agents on smart displays, reflect on their continuous on-screen presence, present user considerations on their appearance, and how the visualization influenced the politeness of the users.
