What surfaces work best?
Knocki activates a wide variety of solid surfaces as control interfaces. See what types of surfaces work with Knocki.
For best performance, we recommend always using Knocki with the mounting bracket. There are several ways to secure the mounting bracket.
Using 3M strips is recommended for surfaces that you'd like to keep in pristine condition. These strips are specifically designed by 3M to easily remove from surfaces without damaging them or leaving a residue. Two sets of 3M strips are included with each Knocki and can be found on Amazon. To remove a mounting bracket that is secured by 3M strips, see removal instruction.
Using Screws is recommended when attaching Knocki to rough or irregular surfaces where 3M command strips are unlikely to stay attached.
What factors affect how well a surface works with Knocki?
Several factors affect which surfaces work best for Knocki:
- Stability: Knocki works best on surfaces that are sturdy and stable. Tables with wobbly legs, or windows with loose glass panes, or that aren't secured well may cause gestures to be unrecognized by Knocki.
- Activity: Surfaces that are extremely active (such as a dining table during dinner) can drown out gesture signals and make gestures less reliable. We are continuously tweaking and optimizing gesture performance on active surfaces, and will be using real-world data to optimize performance over time.
- Rigidity and Solidity: Surfaces with significant flexibility or that are very soft (or thin) are not recommended. Examples include very thin and light plastic tables or upholstered furniture. Experiment to see what works for you!
What are the best areas of a surface to mount Knocki?
We encourage you to experiment with mounting locations to find the spots that work best for you!
However, we also have a few suggestions to help steer you in the right direction.
In general, we recommend mounting Knocki near the area of the surface where you will typically apply gestures. While you can mount Knocki further away from where you plan to apply gestures, you'll need to tap or knock harder if Knocki isn't as close.
For certain surfaces, we have additional recommendations:
- Granite Countertops - For granite countertops, we recommend mounting Knocki above or under an area where the countertop overhangs. This provides some flexibility in the granite that helps to transfer the signal.
- Tables - On tables, we recommend mounting Knocki near an edge or corner to increase the stability and rigidity of the surface. This suggestion usually helps, but there are exceptions!
- Walls - Walls that are thinner than 2 inches (5 centimeters) are recommended for best range. Drywall and wooden walls are ideal. If you can, avoid bricks, concrete, and cinderblock.
