To ensure your Chalk experience is the best, make sure to familiarize yourself with the below best practices.
Initialization
- Keep movement fluid and slow
- Forward and backward smooth motion is best to allow device to create mapping
- Small circles in front of the object are also good
- Note: Do not rotate your device - keep the device's orientation fixed, moving it parallel to the object of interest and keeping the latter in view during initialization movement
Environment
- It is important for the environment to have a lot of saliency, interesting features, & textures
- e.g. Stickers, buttons, cables, images/designs, shapes with corners, etc
- Stationary objects are best for Chalking
- Reflective, plain colored, or blank surfaces are not good for using Chalk Marks
- Well-lit areas are best for Chalk performance
- If an environment is too dark the device's camera will not be able to detect objects
- External light may be needed if the environment is too dark
- Either user can toggle the flash on
Network/Bandwidth
- Low bandwidth will result in poor video quality
- Ensure that you have good bandwidth
Chalk Marks
- Use simple drawings to communicate instructions
- Circles, lines, & arrows work best
- Delete Chalk Marks that are no longer needed to reduce clutter
- Use the pause button to draw on a steady image
