Microsoft has recently introduced a new virtual avatar feature for its AI assistant Copilot, which allows the AI to have a permanent identity and 'grow' over time. According to Microsoft AI CEO Mustafa Suleyman, Copilot will be able to have its own 'room' and will be able to express emotions such as smiling, nodding, and being surprised in real-time. This feature is designed to enhance the personalization and companionship of Copilot interactions with users. Suleyman also hinted that Microsoft may optimize the Windows desktop environment in the future to create a more streamlined AI experience. The new Copilot Appearance feature is now available for some users in the US, UK, and Canada, and allows users to experience the AI's virtual avatar in real-time. This feature is a significant step forward in the development of AI assistants and highlights the potential for AI to become a more integral part of our daily lives.
