Raspberry Pi 4 with Leap Motion

I'm trying to build a smart mirror with gesture controls, so I was doing research on components and materials. As I did my research, I came across a motion sensor called leap motion, which I am intrigued to use. However, I also find out that you can't just plug leap motion into a Raspberry Pi, since there are too much to process in leap motion. This was 4-5 years ago. Now that Raspberry Pi 4 is out with a more powerful processor (https://www.raspberrypi.org/products/raspberry-pi-4-model-b/specifications/), can Raspberry Pi 4 run leap motion's tracking software?

Unfortunately the Raspberry Pi 4 still doesn't hit the required specifications.

I searched for the same and found that Windows does not plan to support Raspberry Pi4 as they did with v3 so no luck with them. As for linux.. the guys at Raspberry would say that it is powerful enough.

The problem here is not the OS but the processor. If you try to install Leap Motion on a non x86/64 architecture, it won't let you do it.

So the only solution is through wireless control with Cylon.js and visual scripting with Vuo that you mentioned in this forum (http://blog.leapmotion.com/integrate-leap-motion-arduino-raspberry-pi/)?

Correct, at least at this point.

Since you can't install the leap motion SDK on the raspberry pi 4, what does the set-up look like? The leap motion is connected to your laptop (in my case Macbook) which has the SDK installed. Then you have the cylon library installed using npm/yarn on the laptop. I can connect wirelessly to the raspberry pi via SSH, does this mean I can send leap motion data wirelessly to my Pi? cylon-raspi library needs to be installed on the Pi and not my laptop right?

Correct, the processed hand data can be sent to the Pi. I believe the cylon library does need to be installed on the Pi, but that would be in their documentation.

So I want to attempt this setup:

Laptop (Macbook):
- Leap Motion SDK installed
- Leap Motion device connected

Pi:
- all cylon packages installed
- cylon code to connect to the leap

Can the websocket server running on my laptop be accessed from other devices on my network? From my laptop, a cylon app can connect to my leap device no problem because it's localhost:6437. But I get connection refused using the ipv4 address of my laptop, which is something like 10.0.1.x.

I figured it out, I was just missing a runtime configuration: "websockets_allow_remote": true. For anyone else interested, you need to make sure the leapd daemon is stopped before editing the config.json.
