About Me

My name is Wolf Paulus, a photographer, hiker, hacker, technologist based in Ramona, California.

Inspire and innovate, emphasizing wearables, voice user interfaces, speech recognition and synthesis, NLU, and AIML.

I am focusing on embedded, mobile, and open source technologies and help accelerating the discovery and adoption of emerging mobile technologies.

Software

I created the Java-based open source XUL Engine SwixML, which Sun’s CTO called “The strongest straightforward design of declarative UI implementations”.

SwixML represents ideas that today are heavily re-used in Google’s Android SDK. (Graphical User Interfaces are described declaratively in XML documents that are parsed and rendered into UI widgets hierarchies at runtime.)

But I have create so much more that I’m extremely proud of.

Mobile

A lot of my work evolves around early technology prototyping. Still, I’m trying to put some ideas into real world mobile applications.

Take a look at Artist on Android, the Horsemen of Speech Recognition, or other apps that I have published under the Techcasita Productions brand in Google’s play store.

Cloud Services

Most mobile applications consume some sort of cloud service. Speed is extreme important for Voice User Interfaces to work well, which means you want to do as much as possible on-device. However, speech recognition accuracy and speech synthesis quality often requires to implement these services in the cloud. Cloud services that I have recently implemented include speech synthesisaggregation, AIML based natural language understanding, and text summarization, including simple sentiment analysis.

PRESENTATIONS

I’m appointed to the advisory committee for the Mobile App Development Certificate at the University of California, Irvine, and occasionally speaks at conferences and user groups on topics ranging from Embedded Technology to Declarative Programming, emphasizing UI Generation at Runtime, and everything Voice User Interface related of course.

Have a look at some slide from my most recent talks.


INSPIRING VIDEOS

Many new concepts that I implement in mobile applications, are communicated best through video clips or short films.

Take a look at some high quality short HD films that I have created over the last few months and years.


STUNNING PHOTOGRAPHS

“Amateur Professionalism”, a concept used since 2004, describes an emerging sociological and economic trend of people pursuing amateur activities to professional standards. That pretty much describes how I look at my photography work today.

Too Close for Comfort?

The DJI Phantom Quadcopter is a real screamer. It’s loud, uncomfortably loud, sometimes even confused for a massive bee swarm. Don’t blame the motors, since with the propellers removed, the phantom sounds just like any other quadcopter with inexpensive motors.
So for a long time now, I have been looking for the ultimate propeller for the DJI Phantom.

Blade pitch or simply pitch refers to turning the angle of attack of the blades of a propeller or helicopter rotor into or out of the wind to control the production or absorption of power.

HTC One M7 gets Lollypop – and here is how

About one year ago, I got an HTC One (M7) Android phone. Arguably, at that time and maybe still today, the prettiest Android phone yet. It’s heavier than its peers, the camera is inferior to some Android phone, but much worse than what’s available on the iPhone, and still its beautifully built, with much attention to detail, an almost perfect blend of metal and plastics.

I got the phone with an AT&T contract, meaning it had the HTC skin, aka HTC Sense, and lots of AT&T bloat-wear pre-installed, un-removable of course. My threshold for this kind of annoyance is admittedly rather low and I had the phone rooted, replaced the recovery image with TWRP and installed the pure Android experience of the Google-Play-Edition version of this phone, after about one week of usage.

This is all good, until the next Android update becomes available, which won’t easily install with a custom recovery (TWRP) installed. Having done this many times, it’s still a little nerve-wrecking, considering the many stories about boot-loops and bricked devices.

Icarus 3.0 – I think we finally got a winner

Third time’s a charm. After building two quad copters, which handling and behavior could not remotely compare with off the shelf copters like the the DJI Phantom, I think we finally got it right.

Icarus 1.0

The 1st attempt was a simple quad copter design (Wood Booms 1/2″ X 10″) utilizing HobbyKings’ HKPilot Mega V2.5 Flight Controller and GPS, a cheap ArduPilot knockoff. The resulting lightweight copter with a 600mm (24″) wheelbase looked promising, but the unreliable controller and GPS caused erratic behavior once airborne, eventually resulting in some painful cuts.
