Summer 2016 interns at HP Labs – Cody Carlton



Cody Carlton had never taken a course in computer science before arriving at college. But he decided to try programming in his freshman year at Stanford University and ended up taking three CS classes. Now a rising sophomore, he’s thinking about majoring in either computer science or management science and engineering. Home for Carlton is Fort Collins, Colorado, where he grew up loving the outdoors and where he’s returned this summer to intern at HP Labs’ Fort Collins outpost. “Both the Rocky Mountains and HP are ten minutes from my house,” he says, “so it’s worked out pretty well.”  



HP: So what are you working on at HP Labs this summer?


I’m working on a couple of projects in the Print and 3D Lab. My primary project is on progressive QR codes. These have a 2D black and white bar code, plus information encoded in color – and then those colors also change over time. You can encode something like a serial number into the bar code to track an object as it moves around. Then you can put color into the white spaces in the code to relay other information, like whether or not the item has been tested, and then change the color as it moves through the manufacturing or delivery process. I’m writing code that will read black and white bar codes and then map where the colors are as they change over time.

Summer 2016 interns at HP Labs – Swetha Revanur



Swetha Revanur only just graduated from high school in San Jose, California, but has already co-authored a paper in Nature Communications, built a health education app, interned at the National Institutes of Health, and placed first in bioinformatics research at the 2015 and 2016 Intel International Science and Engineering Fairs. Now she’s interning for the summer in HP’s Emerging Compute Lab before entering Stanford University in the fall, where she hopes to major in computer science.


HP: How did you get interested in data and computer science?


When I was a freshman in high school I did a project in my history class about a disease called Hidradenitis suppurativa, which is a skin disease almost no one has heard of but affects an estimated 1% of the global population. I started to look at the genetics behind the disease and came across these huge databases of information and realized that the best way to take advantage of that data was with computer science.

Summer 2016 interns at HP Labs – Camille Eddy




Camille Eddy has wanted to be an astronaut since the age of twelve. That led the native of Idaho to focus on engineering and computer science as she was home schooled through high school and then to major in mechanical engineering at Boise State, where she’s a rising senior. “I see robots and artificial intelligence as having some really cool applications for space and for technology in general, and I just want to keep driving towards that,” she says. Already making her mark, Eddy was chosen to introduce President Obama when he visited Boise State to speak about education and innovation last year and is the recent recipient of a McNair Scholarship, a program that prepares students who are traditionally underrepresented in graduate education for doctoral studies through involvement in research and other scholarly activities.


HP: What are you working on at HP Labs this summer?


I’m working in the Emerging Compute Lab and our summer project is teaching a telepresence robot how to find a conference room and open the door by itself. There’s a team that’s working on the navigation part of it and my responsibility is programming the mechanical arm that grabs the door handle and turns it.

Summer 2016 interns at HP Labs – Xi Liu



Michigan State University Ph.D. student Xi Liu is interning this summer in HP’s Print and 3D Lab, where she’s excited to be taking on new challenges in data mining, her main area of research interest. “Some companies just tell their interns what to work on,” she notes. “But at HP Labs, you can find something that both you and your advisors care about, so it's a great opportunity to get interesting work done.” Xi grew up in the heart of the ancient Chinese city of Xi’an and attended the Xi’an Jiaotong University, where she received her BS in electrical engineering. She’s now a rising fifth year Ph.D. candidate in computer science and engineering at Michigan State. Outside of work, she likes to hike and play violin.


HP: What are you working on at HP Labs this summer?


I’m looking at data from sensors like accelerometers and RGB/D cameras (which detect depth as well as record RGB images) that track human activity. We’re trying to see if we can automatically recognize what people are doing from that data, detecting whether they are sitting or standing, for example, or moving around. I’m creating a framework that allows us to extract the features of different activities from the raw data. And then I’m writing algorithms that let us take the features and identify them as specific activities.

Summer 2016 interns at HP Labs – Baris Unver




Baris Unver was born in Istanbul, Turkey, where he began coding and building electronic systems as a young teen. He attended the Kuleli Military High School and Turkish Military Academy, receiving a BSc in systems engineering, before embarking on twelve years of military service in the Turkish Gendarmerie’s Signals Corps. He then studied for an MSc in information technology at Hacettepe University in Ankara, Turkey and is now enrolled as a Ph.D. student in computer science at the University of Minnesota, where he is focusing on human-computer interaction within GroupLens Research.


HP: Can you describe the project you are working on at HP Labs this summer?


I am working on projector camera systems, like the HP Sprout, which is the only pro-cam system on the market. Pro-cam systems have both video conferencing and a shared “live” stage that each party can work in, so each person can draw or play with objects on that stage as they work together. I’m interested in seeing how we can reinforce social relations with these systems and also enhance workspace collaboration and distance learning. This summer, I’m working with my Ph.D. advisor, Professor Lana Yarosh, and Dr. Alex Thayer in HP’s Immersive Experiences Lab build an app that lets pro-cam systems interact with people who only have access to a PC or mobile device.


HP Labs researchers create a metal-based, permanent charge roller for HP Indigo digital presses



Announced at the 2016 DRUPA international print media fair, the HP Indigo 7900 Digital Press features a new, HP Labs-engineered charge roller that many experts in the field had believed to be impossible to create.


The charge roller initiates the printing process by laying down a uniform electrical charge onto a photosensitive drum, which is then selectively discharged to form the latent image. Unlike all other commercial charge rollers, which are made from a conductive rubber exterior, HP Labs’ new charge roller is made from metal, a counterintuitive choice given that the rollers need to be highly electrically stable while in operation.

HP Labs and HP’s printing business collaborate on HP’s new Jet Fusion 3D Printing System

Voxel Banner.jpg


HP’s new Jet Fusion 3D Printing System, announced last month at the 2016 RAPID 3D printing and additive manufacturing conference in Orlando and set to reinvent how companies prototype and produce functional parts, started out as an under-the-radar collaboration between a small group of researchers drawn from HP Labs and HP’s printing business group.


Company leaders had observed the 3D print industry from its inception, but had yet to arrive at an approach that they could fully support, explains Lihua Zhao, senior research manager and lead for HP Labs 3D Print research. But four years ago, four engineers in HP’s Barcelona print business research lab began talking with several counterparts in HP Labs.

Mining data within a complex sales, service, and provisioning pipeline can yield powerful insights



An HP Labs research project is applying data science to a central concern of any services business: maximizing the company’s return on the time and money it invests in selling and then provisioning those services to its customers.  


It’s a particular challenge for companies like HP that offer services supplying customers with physical materials, such as printers and ink, on a large scale, and where the contractual engagement cycle for those services can easily extend over a long period of time.


Now, in a collaboration with HP’s Managed Print Services (MPS) business unit, HP Labs researchers are exploring how to shorten that cycle while also gaining key insights into how machine learning can improve the contractual service experience for both HP and its customers.

Such a Weigh with Words

800x200_2 - Copy.jpg


This is another blog in our series on how the HP Way and the combined weight of HP’s research, business practices, and heart – what I call “the HP Weigh” - can contribute to a better future. Feel free to weigh in!


Do you still have a weigh with words? Or has the premise behind the Shallows, which argued that the Internet is negatively influencing “how we think, read and remember,” and is one of the landmark books of this decade, proven true in your increasingly referential brain? In this blog, we briefly discuss the history and the power of text to motivate, liberate, and educate, and consider the magic of text in a world increasingly crushed by the now-mundane pervasiveness of video. We then consider the many different ways in which we can add emphasis, or emphasis, or even emphasis, to text. Hopefully, when you finish looking over this, you’ll have a renewed love of the art of reading.


Is there, in fact, more creativity in text than in video? Maybe so. And in this age of video and other multimedia, what role does millennia-old, humble text play? More than you might think. Keep in mind that text is not just the first word, it is also the last word. And word is, text is not just content, it is form and shape as well.

Exploring hybrid solutions for immersive learning



Despite the easy availability of digital multimedia, students still like to read instructional materials printed on paper, notes Yang Lei, a research scientist in HP’s Print and 3D Lab where the future of education has been a major avenue of inquiry for the past few years.


“When we survey people, many say they prefer to read print books,” Yang explains. “But printed materials don't offer the array of features and the rich learning experience that’s possible with digital materials. So as we’ve been developing a vision of the teaching media of the future, we’ve wanted to imagine a hybrid solution that offered the best of both worlds.”


The lab’s newest educational technology, dubbed the HP Personalized Hybrid Learning App for Sprout, achieves that goal via customized printed instructional materials that seamlessly interact with online resources.

The citation reads: “awarded to the student with an exceptional interactive technology project or startup; both of which are the future.”



High school programmers meet at HP Labs for the third annual ‘CodeWars Silicon Valley’



HP-CodeWars-Logo_web.jpgOver 200 high school students, coaches, and chaperones converged on HP Labs’ Palo Alto headquarters last weekend to compete in the third annual ‘CodeWars Silicon Valley,’ a student coding competition jointly sponsored by HP Labs and Hewlett Packard Labs.


The competition, run entirely by employee volunteers from the two companies and open to all high school students, public or private, drew 50 teams from 16 schools, including two from Southern California. The students were asked to tackle a set of 21 coding challenges over a period of 3 hours using Java, JavaScript, C/C++/C#, or Python, sustained by a steady supply of classic techie foodstuffs such as bagels, donuts, and chips.


Trophies were awarded to the top novice and advanced teams, with raffle prizes of HP technology and giveaways to all participants.


This year’s winners:

Advanced Division: 1st Aragon High School, 2nd Carlmont High School, 3rd Cupertino High School, 4th St Francis High School (Mountain View)


Novice Division: 1st Cupertino High School, 2nd Proof School (San Francisco), 3rd Cupertino High School, 4th Evergreen High School

The HP Weigh: Diversity and the Hardy-Weinberg Principle

800x200_2 - Copy.jpg


This is the second in a series of blogs on how the HP Way and the combined weight of HP’s research, business practices, and heart – what I call “the HP Weigh” - can contribute to a better future. Feel free to weigh in!


Driving diversity is a hot topic in board rooms, leadership conferences, and STEM classrooms. Like many companies, HP has a team that is specifically focused on educating, measuring, and improving diversity across our company.  This interest in diversity has generated research studies on the financial benefits and business case studies to prove or disprove the moral case. These studies provide persuasive evidence on improved financial performance when a more balanced number of women are included on boards and management. Motivated by this research companies such as Volvo, L’oreal and KPMG are using diversity to expand creativity, innovation, and robustness of design by actively filling traditional men only roles, such as car design, scientific research, and senior leadership with women.

Interaction designer Ji Won Jun joins HP’s Immersive Experiences Lab



jwj_thumbnail.jpgJi Won Jun is one of the newest members of HP’s growing Immersive Experiences Lab, joining the team as a research engineer at the start of the year. Originally an interaction designer, Jun moved into Human-computer interaction research driven by an interest in technology and how we think about the future. “I see my job as bridging the two,” she says, adding that “the future hasn’t happened yet, which means that there are so many things that we can do - that’s the really exciting thing about this work.” Jun received her B.F.A. in Visual Communication Design from Kookmin University in Seoul, South Korea and an M.F.A. in media design from the Art Center College of Design in Pasadena, California. We checked in with her to hear what she’s hoping to explore at HP Labs.



Multimedia and the future of knowledge




Last November, I was invited to speak at the Bay Area Multimedia Forum. The weekend before the event, I had complete pharyngitis, to the extent that I couldn’t speak Saturday or Sunday at all. While this made my family and friends enjoy a nicer weekend than usual, it meant I was worried I would have to cancel the talk. Luckily, just enough of my voice came back to give a gravelly, but hopefully still relevant talk on the following outline:
