Placemeter and Traffic in The Willows

[I started this project back in November 2015.  The project started nicely but never reached full speed and I didn’t find a natural time to write about it… until now]

In Fall 2015 I discovered Placemeter [Washington Post, TechCrunch, WebSite], a startup in NYC that used Computer Vision to track pedestrian and vehicular traffic.  At that point our local neighborhood was seeing a lot of car cross-through traffic, so I started a project: use Placemeter services to track traffic in several key locations in the neighborhood, correlate the traffic to infer flow, and then use this to have a more educated conversation with our city council.


Placemeter has two different operating modes.  In both modes different areas of the field of vision are marked for analysis, either as a turnstile, to track objects going through it, in both directions, or as a polygon, to track objects going in and out of the area delimited by the polygon.   Placemeter applies CV algorithms to count the objects, to do object classification (pedestrians, cars, trucks, bicycles), and to do speed analysis.

A Modern RFID App Using NativeScript


Mehfuz has finished a first pass at an RFID scanning app for the Invengo XC-1003 (see earlier progress reports: part I and part II) leveraging NativeScript.  You can see the code for the app at GitHub.

Linux Inside … ThingMagic Sargas


Our ThingMagic Sargas just arrived.  This is a small (87mm x 80 mm x ) fixed RFID reader that packs a nice punch.  It has 2 high performance UHF RFID antenna ports capable of reading 750 tags a second at distances over 9 meters and an ethernet port, but it also has a BLE, USB, 4 GPIOs, micro-SD, and HDMI.  Inside there is a 1GHz ARM Cortex 8 running Linux (Debian) where you can run your own code.

Come for NativeScript, Angular and CouchBase – Stay for a Pokemon

This Thursday (Jul 28, ’16), we are hosting a MeetUp at 6pm at our location in downtown Palo Alto (Google Maps – MeetUp info).  Mehfuz and Nic will show how to create native cross-platform Apps using NativeScript and CouchBase.

CouchBase is an open-source, distributed (shared-nothing architecture) multi-model NoSQL document-oriented database; NativeScript is an open source platform for building cross-platform Native mobile applications using JavaScript and CSS.  NativeScript leverages a high performance bridge between any native platform API and JavaScript which can be used to create Plugins that extend the platform.  Mehfuz and Nic will show how to use the CouchBase plugin in an app where information created by one user in one smartphone can automatically be shared with another user in another smartphone.

Mehfuz will also show how to use his Estimote plugin; combined with the CouchBase plugin, the iBeacon data read by one phone is automatically synchronized to the other.

We are sprinkling a slight IOT overlay on the MeetUp.  We took some of the RFID configuration we used in a Conference App earlier this year and we now have them connected to a Raspberry Pi 3.  UPS-willing, the plan is to add some RFID tags to the badges for the MeetUp and show you how a modern Data Speed Layer (like AMTech.Solutions) can be used to track an asset (you) on a space.

Following the Pokemon Go mania, I’ve ordered some Pokemon figures as prizes for the attendees. Raichu arrived yesterday, others to follow (update – All Pokemons are here; check the Flickr Album).  See you on Thursday.


Capstone ’16 Project at CSUMB – Quantifying the BIT Building

I mentored a Capstone project at Cal State University Monterey Bay (CSUMB) this last Winter.   The project involved quantifying the BIT building using a combination of video cameras running Computer Vision software (Placemeter), iBeacons (Estimote) and GPS, all connected using the IOT Platform from AMTech, and a solutions stack from Progress: Modulus, NativeScript and Telerik Platform.


My post at Progress Blogs has more details.

CSUMB ’16—Quantifying the BIT Building

(this is a duplicate of a post from the Progress Blog)

For their 2016 Capstone Project, students at CSUMB used key Progress technologies like NativeScript and Modulus to create an app with powerful capabilities. Progress VP of Technology, Eduardo Pelegri-Llopart, mentored the team and dives into the technology stack—learn how he and his team developed their app.

Inside the ProgressNEXT 2016 App

This article appeared originally in Progress Blogs

Progress VP of Technology, Eduardo Pelegri-Llopart, and Progress Solutions Engineer, Mehfuz Hossain, take you inside the app they designed for a recent Progress conference. Learn how Progress mobile technology was used to create a powerful, responsive and interactive app.

Our team wrote the conference mobile app for ProgressNEXT ’16, the conference for Progress partners, in Las Vegas. The app provides the usual functionality: event agenda, list of speakers, schedule builder, venue map and events plus a couple of additions: the app helps attendees connect to each other, and the app interacts in real-time with attendees using RFID tags. The app was built using several Progress products: Telerik Platform, Kendo UI, Rollbase and Modulus, and also used an IOT platform from a partner, AMTech Solutions. In this post we describe the architecture of the system; in future posts, I’ll go into more details about the IOT portion.
