# Spatial Accuracy Guidelines for iPad-Only Use Cases

> To achieve stable and accurate spatial alignment when using the app on an iPad, follow the guidance below.

### **Before You Start**

**Ensure the environment supports tracking**

* Use even indoor lighting where room details are clearly visible.
* Avoid very dark spaces or direct sunlight that creates strong shadows.

**Check your device setup**

* Make sure the camera is not blocked by your hands, fingers, or case.
* Hold the device at a comfortable distance from surfaces (about arm’s length), not pressed directly against walls or floors.
* If available, use a device with LiDAR for faster and more reliable tracking, especially in low-detail or dim spaces.

### **Starting or Rescanning a Session**

**Initialize tracking carefully**

* When opening the AR experience, slowly move the device and look around the space for 3–5 seconds.
* This initial scan helps the app establish a stable understanding of the environment before content is placed.

**Include visual detail in view**

* Aim the camera toward areas with recognizable features such as furniture, machinery, walls, or signage.
* Avoid pointing the camera only at blank floors or plain walls, which can cause tracking to drift.

### **During Use**

**Move smoothly**

* Walk at a normal pace and avoid sudden turns, fast movements, or swinging the device.
* Smooth motion helps maintain consistent tracking.

**Maintain stable reference points**

* Keep non-moving objects like walls, furniture, or fixed equipment in view whenever possible.
* Avoid spending long periods pointed only at moving objects.

**Be mindful of reflective surfaces**

* Glass, mirrors, and glossy floors can interfere with tracking.
* When near these surfaces, include non-reflective objects in the camera view.

### **If Alignment Drifts**

**Re-anchor using the QR code**

* The QR code serves as a reference point for alignment.
* If virtual objects appear to shift, move back until the QR code is clearly visible on screen.
* Use the **Rescan QR** option if available.

**Restart if necessary**

* If returning to the QR code does not correct alignment, close the AR view and reopen it to start a new session.
