AI & Human-Computer Interface (HCI)

This section explores the fascinating intersection of advanced AI tools and the physical interfaces we use to control them. Drawing from insights on my WearOS blog, these FAQs use modern smartwatches as a practical case study to discuss how we access and interact with AI beyond a keyboard and terminal.

Q: How does AI integrate with physical user interfaces like smartwatches? A: AI integrates into wearables primarily through advanced voice assistants, like Gemini on Wear OS, which act as a natural language interface for the device's functions. Instead of navigating menus, you can speak commands to manage tasks, get information, or interact with apps. This turns the watch into a more hands-free, conversational tool, where the AI orchestrates actions across different services like your calendar and messages based on your voice requests. Currently Anthropic's Claude does not have a presence on WearOS, however I will be experimenting with different methods of interfacing with Claude on WearOS.

Q: What are the current challenges in accessing AI on wearable devices? A: A primary challenge is that hardware design often lags behind AI's growing importance. On many smartwatches, including the Galaxy Watch series, the most accessible physical buttons are restricted to core, non-AI functions, while AI assistants are assigned to less intuitive actions like a long press. This creates a disconnect where the most powerful tool on the device isn't the easiest to access, highlighting a need for hardware and HCI philosophies to evolve with AI capabilities. Unfortunately Google's Circle to Search like HCI is also not available so there is no context-aware AI experience. Understandably the screen space is limited so a lot of innovation is necessary to make AI experiences work within the constraints of a smartwatch environment.

Q: How do different HCI methods (e.g., Touch Bezel, buttons) affect AI interaction? A: Each HCI method serves a different purpose that can either complement or conflict with AI. Touch/Rotating Bezels: These are excellent for direct, tactile manipulation, like scrolling through a list that an AI has generated. The haptic feedback can make digital navigation feel more precise and physical. It is uncommon to use touch/rotating bezel to activate AI, however it can be worth exploring generated lists of options which are automatically displayed on interaction. If activation and navigation are done in a single motion the HCI can provide a seamless AI experience. The alternative requires a user to navigate between two different HCIs to achieve a task (touch screen, touch/rotating bezel). Touch Screens: Best for direct visual interaction with app interfaces, however due to the small screen it requires a user to either perform multiple actions to scroll through the options generated the AI or for the AI to provide concise answers which deliver finite value. There is also the alternative of using audio but this is not necessarily the ideal modality for when a user is in a publicssetting. Buttons: Ideal for instant, muscle memory access to critical functions. The friction occurs when these systems don't work in harmony. For instance, having a highly responsive AI assistant is less effective if its activation is buried in a secondary button function , forcing a less efficient interaction pattern.

Q: How could we monitor complex AI tasks, like those using sub-agents, from a watch? A: Monitoring advanced AI on a small screen requires a shift from detailed logs to intuitive visual indicators. Drawing inspiration from how Claude Code shows a flashing bubble for its Task tool a watch could use a dynamic complication on the watch face. For example, if you ask the AI to plan a weekend trip, a complication could appear showing an icon with 3 agents active. Tapping it could reveal that the Flights, Hotels, and Activities sub-agents are working in parallel, with simple progress bars for each. This provides at-a-glance status without overwhelming the user. Alternatively the subagent processes could have dedicated WearOS tiles which displays the on-going status of agents.

Q: What is the role of haptic feedback in AI-powered interfaces? A: Haptic feedback is crucial for making digital interactions feel tangible. On my Galaxy Watch Ultra, the Touch Bezel uses haptics to simulate the click of a physical bezel, providing confident, precise control. In an AI context, haptics can confirm that a sub-agent task is being completed, it could be used for indicating the kind of issue an agent is experiencing or it could be used to indicate the progress within an on-going task. The additional sensory experience compliments the existing audio feedback which is provided via the terminal when interfacing with Claude Code subagents. In the future, distinct haptic patterns could even signify the status of background AI tasks (e.g., one buzz for success, two for an error).

Q: How does the concept of "context awareness" in AI apply to wearables? A: Context awareness is the ability of a system to understand your situation and act accordingly. I've seen a simple version of this in the Touch Bezel on my WearOS watch, which automatically knows to control volume during a call or scroll through tiles from the watch face. A truly context-aware AI on a wearable would take this much further, using sensor data (location, heart rate, calendar) to anticipate needs. For example, it might proactively suggest a less stressful route to your next meeting if it detects an elevated heart rate and sees traffic delays. This is similar to how Claude Code uses the context of an entire codebase to inform its actions. Other sensory data could also be interpreted by AI to determine what kind of functionality or suggestions to provide a user when interfacing with an aspect of a watch e.g., buttons or the physical bezel.

Q: How will wearable interfaces need to evolve for an AI-first future? A: The current app-centric and tile-based model will likely become secondary. The future interface will be a dynamic, goal-oriented canvas orchestrated by an AI agent. Instead of you opening four different apps, you'll state a goal like, Help me prepare for my presentation, and the AI will assemble a temporary UI with your notes, calendar event, teleprompter controls, and stress-monitoring from the heart rate sensor. The interface will fluidly adapt to your task, moving beyond rigid grids of icons to a truly intelligent and responsive user experience. The generated interface would be navigable via standard methods e.g., touch scrolling or touch/physical bezel. I believe the future of WearOS is to build lightweight dynamic experiences which adapt based on the contextual and sensory data provided by the user.

Q: How could an AI like Claude influence future wearable interfaces? A: While current assistants like Gemini are great for executing commands, a more advanced AI could bring deeper reasoning and workflow automation to wearables. Imagine a Claude for WearOS that doesn't just respond to requests but helps you plan and execute multi-step tasks. You could ask it to review my last workout, compare my heart rate zones to previous runs, and suggest an interval plan for tomorrow, and it would analyze the data, generate a plan, and schedule it in your calendar—a level of complex reasoning that goes beyond simple task execution.

Q: How could AI make battery warnings smarter and more useful? A: Traditional battery warnings are reactive; they tell you when power is low but lack the context of what you need to accomplish. An AI could transform this by acting as an intelligent advisor. By understanding your calendar, location, and usage patterns, it could provide proactive, actionable advice. For example, instead of a simple 15% battery remaining alert, it might say: You have 15% battery left. This is enough to get you home via your normal transport routes or You have 15% battery left and are on route to arrive at your destination with 5% battery remaining. WearOS's Gemini integration AI integration is rudimentary and I am personally exploring what kinds of HCI experiences can be created with Claude on WearOS.

Q: What are the most powerful devices that can handle AI on WearOS? A: Any of Samsung's modern Galaxy Watch 7 series watches or newer have the Exynos W1000 chip, which is powerful enough to enable us to build complex fluid experiences. I personally have the Galaxy Watch 7 Ultra and Galaxy Watch 8 Classic and am exploring what the SOTA AI X HCI experience could be like on a wrist.
