🤖 Step 5: Advanced Automation (Camera Driver & Preset)

WristSnap has completely upgraded its Camera Driver and Preset systems. The new system bids farewell to the rigid "record click coordinates" method and adopts an advanced approach integrating node trees, state machines, visual features, and OCR text extraction.

Through the standardized workflow of "Create Driver ➔ Record Nodes ➔ Configure Preset ➔ Auto-Train", you can empower the app to truly "understand" camera parameters, enabling precise and automatic execution of any complex camera configuration.

The overall workflow is divided into the following five core phases:

1. Create Driver

The Driver is the "instruction manual" connecting WristSnap to your phone's camera. In this step, you will define the basic operation hierarchy of your camera app.

• Select Target: Choose the camera app you want to control and confirm the current environment language (e.g., English, Chinese).
• Build Node Tree: Why design a node tree? Because mobile camera control interfaces usually have strict sequential and hierarchical relationships. For example, on most phones, you must first switch to "Pro/Manual Mode" before you can see and adjust the ISO, shutter speed, or white balance. This dependency of "entering the main interface first, then expanding sub-menus" branches out like a tree, hence it is called a "node tree".
• Default Root Node: To simplify operations, the system has built-in the core starting point of the entire framework—"Pro/Manual Mode (MODE)" as the default root node, so you do not need to create it manually. When you want to add any other specific parameters to be configured (such as "ISO", "Shutter", "Filter", etc.), you must bind them as branches under this default "Pro/Manual Mode (MODE)" parent node.
• Constraint Group (Optional): If certain parameters cannot be active simultaneously (for example, in some cameras, adjusting ISO is disabled when auto-shutter is on), you can declare these limitations by setting a "Constraint Group".
• Support Screen Rotation: Configure whether this driver allows automatic coordinate mapping when switching between portrait and landscape orientations.
• Properties & Configuration Review: After the driver is created, you can use Rename and Edit Description at any time. In the description editing interface, the system will intuitively display the full configuration status of all current parameter nodes, making it easy to review the overall structure at a glance.

2. Record Driver Nodes

This is the most crucial step. Upon entering the recording engine, you will see the Recording Task List interface, which lists all the nodes you created in the previous step. You need to "teach" the operation steps for these nodes one by one. (Note: You must record the parent node before you can record its corresponding child nodes.)

The complete recording of each node consists of the following four stages:

Stage A: Pre-state Preparation

After tapping "Record", the engine will automatically execute all operations in its preceding path to guide the camera interface to the correct state before adjusting the parameter (e.g., before recording "ISO", the system will automatically tap to enter the completed state of the built-in root node "Pro/Manual Mode").

Stage B: Record Entry Operations (Navigation)

Use the Operation Recording (Navigation) function on the floating console to record how to expand the parameter's panel:

• 👆 Click: Record a standard screen tap action.
• 🔍 Search: Box select specific icons or text on the screen; during execution, the engine will automatically find and click this position via visual image matching or OCR (ignoring screen size and layout changes).
• ⏱️ Delay: Adjusting this parameter allows you to modify the default wait time added by the system after the previous action (to allow time for camera UI animations to unfold); alternatively, you can choose to insert a completely independent pure delay step directly into the action flow.
• ↩️ Back Key: Simulate the system's physical back button.

Stage C: Record Core Parameter Logic

When the camera's parameter adjustment panel is expanded, select the corresponding recording method in the Parameter Recording area of the console based on the physical form of the parameter:

• 1️⃣ Value: Suitable for sliders with explicit scale readings (e.g., ISO 100-3200, Shutter 1/50-30s). You need to define the physical start and end points of the sliding track and box select the Value Readout Area (ROI), and the engine will automatically explore the limit values.
• ％ Percentage: Suitable for sliders with no specific scale values (e.g., beauty level, smooth zoom). You only need to mark the 0% start point and 100% end point of the track.
• 🔲 Option: Suitable for parallel button/text options (e.g., white balance modes, various filters). Supports manually box selecting target features, or using "🤖 Auto Extract" to let AI automatically scan and extract all option features within the area.
• 🎯 Click(Param): Suitable for blind-spot parameter switches at fixed positions, recording parameterized touch control at specific coordinates.

Stage D: Exit Phase & Reset Operations

CRITICAL! After parameter adjustment is complete, the camera often remains in that parameter's secondary menu.

1. Click the 🚪 Record Exit button on the console.
2. Continue using basic operations (Click, Search, Back Key, etc.) to record how to close the current parameter panel.
3. Goal: Restore the camera interface to the default state from "Stage A" so that subsequent parameter adjustments can seamlessly connect.
4. Once recording is finished, click ✅ Save Operation.

(💡 Tip: During recording, you can always click the "📑 Steps" button on the console to view the recorded action flow, and you can click any step to revert and prune / re-record. After saving, you can click "🎯 Test" in the task hall to verify the stability of the closed-loop sequence.)

3. Edit Preset

Once the driver is created, you can use it to freely combine various "one-tap master configs".

• Enter Preset Management and click Add Preset.
• Select Camera Driver: Choose the camera driver you just created (or downloaded from the Cloud Hall).
• Configure Target Parameters: Check the parameter nodes you want to adjust in this preset (e.g., "ISO", "Shutter", "White Balance") and set specific target values for them (e.g., set ISO to 100, White Balance to "Daylight").
• Preset Management & Review: Name and Save Preset. After saving, you can similarly use Rename and Edit Description for the preset at any time. In the preset's description editing interface, you can clearly view the specific configuration values of all parameters under the current preset at a glance.

4. Preset Auto-Training

This is a fully automated "magic" phase. When you set specific numerical targets for a new preset for the first time, the app requires an actual physical calibration:

• Click Train.
• The app will automatically launch the camera and navigate into the various parameter panels based on the driver's guidance.
• The system will utilize underlying visual recognition (OCR/visual template matching) to pull sliders in real-time and observe the screen readings until it finds the exact physical coordinates that perfectly match your set target values.
• Once training is successful, these results are persistently saved as a dedicated configuration file. Every time this preset is applied thereafter, the app can accurately reproduce it at maximum speed without needing to search again.

5. Trigger & Apply Preset

Once everything is ready, you can use the following three highly convenient methods to wake up and execute complex camera parameter configurations with a single tap at any time:

1. In-App Execution: In the preset list, tap the Apply button directly.
2. Desktop Shortcut: Use Send to Desktop to place frequently used presets on your phone's home screen; tap the desktop icon when needed to instantly launch the camera and auto-adjust parameters.
3. Smartwatch Integration: Within the WristSnap mini-program on your Amazfit/smartwatch, select the corresponding preset to trigger remote execution with one tap.

📥 Privacy & Security Notice

WristSnap takes your personal privacy and data security extremely seriously, implementing the following optimizations and restrictions:

• Full Local Recognition: All built-in image recognition, OCR text extraction, and feature matching technologies run entirely offline on your phone (Edge AI), and will never upload any images or screenshot data to cloud servers. To guarantee high-precision recognition without network reliance, we have integrated robust local offline algorithm models—this is also the main reason for the increased installation package size of this application.
• Lens Cover Strict Interception: To completely eliminate potential privacy exposure risks during automated execution, the system incorporates a strict interception mechanism. During driver recording or preset auto-training, whenever the system needs to capture a screen image for feature recognition, the underlying engine will first detect whether the phone's camera lens is fully covered. Since phones generally lack physical lens caps, you can place your phone face down flat on a desk or use your hand to tightly cover the front and rear cameras during recording and training. If it detects the lens is not fully covered, the system will instantly interrupt the current recording/training process and pop up a red warning prompt ("Privacy Protection: Lens not fully covered!"), and will only allow continuation once the lens is completely obscured, 100% protecting your real-life privacy from being recorded.

☁️ Step 6: Cloud Hall & Resource Sharing

WristSnap introduces a decentralized Cloud Hall ecosystem. Our vision is to build a collaborative community where everyone contributes and shares high-quality automation commands. In the future, you will be able to download top-tier camera drivers and presets shared by geeks worldwide with a single click, enjoying a true zero-config, out-of-the-box experience.

To ensure the highest level of security and privacy, the system utilizes account-less authentication (Ed25519 key pair), allowing you to explore the cloud without linking a phone number or email. Since all cloud interactions require an identity credential, we will start with "My Cloud".

1. Establish Cloud Identity (My Cloud)

This is your cloud digital identity and private asset console, and the prerequisite for all cloud operations:

• Generate New Identity: On your first use, generate a digital identity based on local encryption algorithms with one click and set an exclusive "Geek Code (Nickname)" for yourself.
• Paste Key to Restore Identity: When you change phones or reinstall the app, paste your backed-up key string here to instantly recover all cloud assets and your historical nickname.
• Copy Key to Clipboard: CRITICAL! Your private key is the only credential to retrieve your cloud assets. After passing the standard system authentication (fingerprint/face recognition/device PIN), you can copy and securely store it in your notes or password manager.
• Edit Nickname: Change your public display codename at any time (to prevent abuse, there is a 30-day cooldown period after modification).
• View and Manage My Cloud Assets: Clearly lists all the drivers and presets you have backed up to your private space or shared to the public market. Here, you can toggle the sharing status (public/private), or directly Delete the resources you have uploaded to the cloud.
• Deactivate and Erase Profile: Provides ultimate control over your data. Executing this will irreversibly erase your cloud profile, destroy all public and private backups in the cloud, and simultaneously clear all presets and drivers in your local sandbox.

2. Explore the Cloud (Discover)

The central hub for obtaining community open-source configurations:

• Select Target Camera: You must first select a target camera based on your locally saved camera records (or by adding a new one). The hall will use this as a smart environment filter, automatically filtering out profiles that are incompatible with that app or your device's screen configuration.
• Dual-Track Resource View: Provides two independent channels, Drivers and Presets, allowing you to search for underlying drivers or advanced automation playstyles as needed.
• Read-only Protection Mechanism: To protect the rights of original authors, all drivers and presets downloaded from the Cloud Hall are locked in a "Read-only" state and cannot be secondarily edited or modified.
• Multi-Dimensional Sorting: Sort resources by "Newest", "Downloads", and "Likes" (Favorites) to help you quickly find the most popular and stable high-quality configurations.
• Block & Report: Help maintain the community environment. You can block users via Block Author (isolating all their historical and future resources) or use Report Violation for resources containing malicious parameters or misleading descriptions.

3. Manage Favorites

Manage all your desired configurations bookmarked in the cloud:

• View My Favorites: Centrally displays all the drivers and preset resources from others that you have "hearted".
• Manual Data Sync: Configurations shared by others may be continuously updated. You can actively tap the Sync button to request a comparison from the cloud. If the original author optimized the config or description, your favorite card will fetch the latest metadata. (Note: If the original author deletes the resource or makes it private, the card will display a tombstone state indicating it is invalid.)

4. Cloud Operations for Local Resources

In your local "Camera Driver" or "Preset Management" lists, you can execute cloud publishing operations for your original assets:

• 🔒 Backup to My Cloud: Upload your hard-earned camera drivers or complex preset commands to your private cloud space to prevent data loss and facilitate cross-device restoration.
• 🌐 Backup & Share Publicly: Publish your configurations to the public market to share your hard work with global geeks using the same device specs.
