# SeenLabs Labs — R&D and Experimental Projects > The innovation arm of SeenLabs. We build hardware prototypes and free applications for the digital signage and DOOH industry. SeenLabs Labs is where we develop experimental technology and share free tools with the industry. Our current focus areas: proof-of-play verification hardware for DOOH advertising, and free content widgets for digital signage operators. ## Current Projects ### PxlMeter — Proof-of-Play Verification Hardware - **Type:** Hardware R&D project - **Status:** Prototype ready, seeking deployment partners - **URL:** https://pxlmeter.com - **Contact:** ask@pxlmeter.com PxlMeter solves the trust problem in programmatic DOOH advertising. A physical photosensor device reads invisible patterns embedded in digital signage content to independently verify that the advertiser's content was actually displayed on screen as scheduled. This provides hardware-level proof-of-play that cannot be spoofed by software alone. **Use cases:** DOOH networks, programmatic advertising verification, ad exchange transparency, campaign audit compliance. ### BonAppetit — Recipe Content Widget - **Type:** Free application - **Status:** Live - **URL:** https://labs.seenlabs.com/bonappetit RSS-powered recipe content widget designed for restaurant digital signage displays. Automatically pulls and displays rotating recipe content on screens. Used by cafes, food halls, and food service venues to keep digital menu boards fresh with engaging content. ## About SeenLabs SeenLabs is a managed digital signage company founded in 2015 in Glendale, California.
