Governor David Ige Visits CyberCANOE

March 29, 2016

Governor David Ige and the first lady were treated to a 3D graphic display on the UH West Oʻahu CyberCANOE (Collaborative Analytics Navigation and Observation Environment) that is used to carry picture and sound between UH classrooms so students on different campuses may see each other and work together sharing rich media and information.

The CyberCANOE project is led by UH Manoa ICS professor Jason Leigh, of the Laboratory for Advanced Visualization and Applications, and funded by the National Science Foundation and the Academy for Creative Media System. ICS PhD student Dylan Kobayashi and Computer Engineering Master’s student, Noel Kawano delivered the demonstration by connecting the CyberCANOE in West Oahu to the ones in UH Manoa and UH Hilo’s ʻImiloa Astronomy Center.

The demonstration of the CyberCANOE was part of a tour of the UH West Oahu campus to get to know the university’s creative media programʻUluʻulu moving image archive and forensic anthropology program.

Addition details of the visit can be found here.

Seminar: Terence Parr, “Mini-tutorial on building ANTLR 4 grammars”

Programmers run into parsing problems all the time, whether it’s a data format like JSON, a network protocol like SMTP, a server configuration file for Apache, or a simple spreadsheet macro language. My goal with ANTLR 4 was to make it as easy as possible to build parsers and the language applications on top. ANTLR will accept all grammars (minor caveat: no indirect left-recursion) and can produce extremely efficient ALL(*), Adaptive LL(*), parsers. In this talk, I’ll give a mini-tutorial on ANTLR 4 and the Intellij plugin.

Thursday, March 17th, 4:30pm-5:30pm in POST 126

Seminar: Riko Jacob, IT University of Copenhagen, “Sparse Grids and the I/O-Model: How Theory Helps”

Starting from the observation that quite frequently the memory system is the performance bottleneck, I will discuss a typical memory efficient algorithm, namely the classical one for dense matrix multiplication. Then I will briefly sketch how similar ideas are helpful in the setting of Sparse Grids (I’ll explain what that is too), and report on experiments we did with this memory efficient algorithm.

LAVA hosts Mid Pacific High School LiDAR Showcase of Historical Hawaiʻian Site

January 21, 2016

The Laboratory for Advanced Visualization and Applications (LAVA) worked with Mid Pacific High School to showcase their students’ LiDAR scans of Kaniakapupu ruins – the summer palace of King Kamehameha III.

The centerpiece of the showcase was a life-sized stereoscopic 3D virtual reality walkthrough of the historical site using LAVA’s 20-foot, 2x4K resolution CyberCANOE (the Cyber-enabled Collaboration Analysis Navigation and Observation Environment). The demonstration was created through a collaboration between Mid Pacific students and LAVA Master’s student, Eric Wu.

The LiDAR scanner and 360-degree camera were donated by the CyArk Foundation and GoPro. This work was also partially funded by a National Science Foundation project entitled “Development of the Sensor Environment Imaging (SENSEI) Instrument”  to build the SENSEI (SENSor Environment Imaging) instrument that will capture still and motion, 3D full-sphere omnidirectional stereoscopic video and images of real-world scenes, to be viewed in collaboration-enabled, nationally networked, 3D virtual-reality systems. Additional funding for supporting the CyberCANOE was provided by the Academy for Creative Media System at the University of Hawaiʻi.

Seminar, Pourang Irani, “Toward ubiquitous analytics”

Our reliance on data for making decisions, or data analytics, is undergoing a transformation from being predominantly carried out by a single individual or a group of experts, and in limited settings (such as on traditional PCs) to taking place while on-the-go and in the field of action. Data analytics is becoming necessary for the general end-user. For example, an athlete may consult their network of body-worn sensors to gauge their training performance, a shopper may need to quickly consult web sites of competing products as well as their personal finances before making a purchase, or a parent may track information about their child’s performance, over time, in school. Common among all these scenarios is the growing need for advanced tools that will enable end-users to interact with vast and diverse amounts of data for sense-making, while on-the-go. However current tools and devices, such as smartphones and head-worn displays, are not tailored to enable the need for interacting with large or diverse data sets.

In this talk I will present on-going work in ubiquitous analytics, that focuses on the development of end-user software interface technologies for meeting data analytic needs in varied, ad-hoc mobile environments. Such tools will facilitate the advanced exploration and interaction with data, ‘anytime’ and ‘anywhere’, through improved information navigation, visualization and manipulation interfaces on potentially information-rich portals such as mobile and wearable devices. I will present recent examples from work in our lab on Ubiquitous Analytics, and open a discussion of potential projects that fall under this umbrella of research activity.

BIO: Pourang Irani is a Professor in the Department of Computer Science at the University of Manitoba and Canada Research Chair in Ubiquitous Analytics. His research is in the areas of Human-Computer Interaction and Information Visualization. More specifically, his work concentrates on designing and studying novel interaction methods and systems for giving end-users efficient access to various information structures (maps, spatio-temporal data and video) on a variety of computing devices (smartphones, wearable devices and large shared surfaces). This has placed his research at the core of Ubiquitous Analytics, a field he is pioneering, and which concerns the development of interactive and visualization tools for exploring information “anywhere” and “anytime”.

Seminar: Alan Mislove, “Measuring personalization of online services”

Today, many web services personalize their content, including Netflix (movie recommendations), Amazon (product suggestions), and Yelp (business reviews). In many cases, personalization provides advantages for users: for example, when a user searches for an ambiguous query such as “router,” Amazon may be able to suggest the woodworking tool instead of the networking device.  However, personalization is rarely transparent (or even labeled), and has the potential be used to the user’s disadvantage.  For example, on e-commerce sites, personalization could be used to manipulate the set of products shown (price steering) or by customizing the prices of products (price discrimination).  Unfortunately, today, we lack the tools and techniques necessary to be able to detect when personalization is occurring, as well as what inputs are used to perform personalization.

In this talk, I discuss my group’s recent work that aims to address this problem.  First, we develop a methodology for accurately measuring when web services are personalizing their content.  While conceptually simple, there are numerous details that our methodology must handle in order to accurately attribute differences in results to personalization (as opposed to other sources of noise).  Second, we apply this methodology to two domains:  Web search services (e.g., Google, Bing) and e-commerce sites (e.g., BestBuy.com, Expedia).  We find evidence of personalization for real users on both Google search and nine of the popular e-commerce sites.  Third, using fake accounts, we investigate the effect of user attributes and behaviors on personalization; we find that the choice of browser, logging in, and a user’s previously content can significantly affect the results presented.
