September 2025 · Berlin — At IFA (Innovation For All) 2025, exhibitors focused on 'hardware that understands you'—no longer relying solely on faster processors to attract attention, but treating products as responsive entities through behavior, form and interaction.
In one corner of the hall, the most crowd‑drawing exhibit was a tennis coach robot that looks like a scaled‑down training machine. It can detect incoming ball trajectories and perform ball‑catching and return drills. In demonstrations the robot adjusted return angles after capturing impact points with low response latency; coaches viewed return statistics and suggestions on a tablet in real time. The on‑site demo resembled a two‑way practice between human and machine: the machine 'learns' shot patterns while people adjust their positioning based on the machine's data.
Near the children's and family tech section, a group of 'cuddly AI companions' stole the spotlight with soft shells and anthropomorphic expressions. They combine voice dialogue, touch responses and simple emotion models: stroke their heads and the robots reply in varying tones; ignore them and they emit gentle reminders. Booth representatives emphasized privacy partitioning and on‑device inference capabilities; demos focused more on 'companionship' and emotional feedback than complex reasoning.
Laptop concepts also took a more dramatic turn. Lenovo showcased a rotating‑screen concept called the ThinkBook VertiFlex, which flips from conventional landscape to portrait display; the company described the design as optimized for 'extreme scrolling and creative scenarios.' Live demonstrations showed portrait mode is handier for browsing long webpages, reading documents or social media, while landscape suits video and collaborative work. The hinge design emphasized solidity and tactile feel, and units at the booth were repeatedly switched to verify durability.
The show also revealed incremental improvements for smart homes: smart lighting now supports finer color‑temperature transitions and zoned control; portable power banks were repeatedly touted for weight reduction and improved charge/discharge efficiency; robot vacuums emphasized obstacle avoidance under complex furniture and integrated wet‑mopping strategies. AI headphones were another highlight, with vendors pitching 'on‑device AI': noise cancellation that auto‑adjusts to the environment and voice assistants that can generate live captions and short translations without uploading audio.
The common theme across the exhibition was clear: it's not just about bigger or faster, but 'better understanding how you use it.' Whether a ball‑catching trainer, a cuddly plush robot that acts affectionate, or a rotating‑screen laptop designed for vertical scrolling, vendors are leveraging interaction details and scenario experiences to capture young users' attention. On‑site visitors often judge not by specs but by a few minutes of interaction to decide whether a product is 'fun enough to buy.'
These 'fun gadgets' at IFA 2025 also exposed issues: practicality and maintainability remain key purchase considerations, and vendors' staged 'scenario magic' needs to be validated over time and by real‑world usage data. Booth staff reported being asked mainly about two topics—privacy and durability—answers to which typically centered on 'local AI inference' and 'hinge lifetime testing.'
For young audiences who enjoy novelty and social sharing, IFA delivered a lineup that trades interaction for attention: hardware is no longer just a tool but is evolving toward being responsive, companionable and reminder‑capable. Whether these products become part of everyday life will depend on mass‑production, pricing and long‑term service performance.
