Core Viewpoint - Meizu has launched its flagship smartphone, Meizu 22, featuring the upgraded Flyme AIOS and a new physical "AI key" on the side of the device, aligning with trends seen in other flagship models from brands like Apple and OPPO [1][4][8]. Group 1: AI Key Development - The introduction of the "AI key" is part of a broader trend among smartphone manufacturers to incorporate dedicated buttons for AI functionalities, moving beyond simple voice assistant activation to more complex tasks [8][9]. - Previous attempts at integrating AI keys were largely unsuccessful due to limited AI capabilities, leading to their eventual removal from devices [11][20]. - The current iteration of the "AI key" aims to provide a multi-functional shortcut that allows users to directly engage AI for context understanding and task execution, enhancing usability and efficiency [14][16]. Group 2: Competitive Landscape - Other brands, including vivo and Nothing, are also adopting similar AI key designs, indicating a shift in the industry towards integrating AI more deeply into user interactions [8][19]. - The effectiveness of the AI key will depend on the maturity of the AI capabilities and the depth of system integration by the manufacturers [22][24]. - The AI key serves a dual purpose, functioning as a traditional shortcut for common tasks while also providing access to advanced AI features, thus appealing to a broader user base [19][22]. Group 3: User Experience and Future Implications - The current AI functionalities are not yet a core habit for most users, raising questions about the necessity of a dedicated physical key for AI tasks [17][20]. - The physical AI key could enhance the accessibility of low-frequency AI functions, potentially increasing user engagement with these features [20][22]. - The strategic placement of the AI key may position it as a central hub for AI interactions in the future, depending on the development of AI capabilities by the manufacturers [22][23].
