This is something I built while learning RL, and I decided to open-source. I noticed that every major RL algorithm (Actor Critic, A2C, PPO, TD3 etc.) would be written from scratch, even though they shared a lot of the same features. And eve

The motion tracking system used by ARKit/ARCore is called SLAM, combination of sensors + camera data if available.

Great question. Partly on device compatibility, but mostly that we can achieve an amazing, reliable experience right now without those anchors. If we weren't getting the accuracy we needed from our current methods, we would have to loo

We've had the solution live in stores for years without any issue. Our algorithms can clean up and filter out unreliable data, based on all of the other data we have, from other APs, from previous data etc.. If they re-fit the WiFi, wh

Thank you! I tried to keep it interesting but not get lost in rabbit holes. We have around 300 hours of ground-truth data now, in 1-second intervals, which we use for algorithm training and refinement. The same as performing a survey, our t

Thanks for the feedback. I wanted to keep it balanced to be accessible but also insightful. To answer your point: we have the digital map, can use that to understand obstacles etc in the space. In some of those larger stores you see in the

All of the videos shown on the speed-run of our technology is on 4 year-old Android devices, such as Samsung S21, Pixel 6 etc.. We always test and gather statistics on older devices to fairly represent what's available, rather than lat

Thanks. Very interested in robotics so that'd be an ideal home, given the SLAM + sensors tech stack.

Yes - one of the limitations with mobile is engaging the camera/quality of the SLAM. With a robot, they're already using SLAM with strong tracking, and controlling the hardware stack means no device limitations (uncalibrated senso

Aside from saving time, I'm bad at writing. Especially emails. I often open ChatGPT, paste in the whole email chain, write out the bullets of the points I want to make and ask it to draft a response which frames it well.

You could say the same about software and app stores. If safety were the top priority, then the safest option is to say no apps, but that isn't competitive or lucrative. Apple's approach is to create safe frameworks and a review p

Looks promising. One feature I'd need is ability to change the resolution to vertical - the same as the video I'm inputting.

I run an AR startup called Dent Reality - Apple lists us in their Indoor Maps program docs. We've built on IMDF to solve this for grocery stores, and provide shopping list navigation with maps and AR. 60 second demo video here: https:
