Keynote 1

Craig Fryar

Data-driven Design for Interactive Entertainment


Presentation of real-life examples of using today’s big-data technologies to inform and validate design and user experience in the area of interactive online entertainment. The scope of this talk will include a brief overview of the basics of “big data” and related tools used to both rapidly and visually analyze what is known as the “Player Journey”. Specific examples using animation and video will be presented to illustrate the power of this approach.


Craig Fryar is the Head of Global Business Intelligence at, an award-winning online game developer and publisher, and a leader in the free-to-play MMO market. Based out of Wargaming Austin, Craig leads the worldwide data and analytic efforts, and is responsible for informing design, development, marketing and senior management with actionable insights and business intelligence.

Prior to Wargaming, Fryar was a Director of Analytics at Electronic Arts, informing design, development and marketing of AAA computer and console games, including Star Wars: The Old Republic and Mass Effect 3. He has served in executive positions leading high-performance, innovative teams in hardware and software technology at Apple, Dell, Seedstage and most recently, the International Accelerator.

Fryar holds a degree in Business and Communications from Texas Tech; married 33 years with 3 teens.

Just Noticeable or Not: More Questions than Answers


Just Noticeable Difference (JND) refers to the minimal(critical) amount of “something” that must be changed for the difference to be detectable by humans. It plays important role explicitly and implicitly throughout our work and life, from sound to smell and from engineering to marketing. “If you cannot measure it, you cannot improve it” (William Thomson); therefore, the scientific measurement and formulation for JND are the prerequisite for user-oriented designs and turning human perceptual (imperfect) sensitivities into system advantages in many circumstances, toward betterment of QoE and QoL (Quality of Life). In this talk, a holistic view will be first presented in JND research and practice, followed by the latest progress in the field, based upon our substantial exposure torelevant projects. As will be shown, JND modeling for visual signals has attracted much more research interestso far, while that for audio, haptics, olfaction, gestation and other forms of signals is expected to intensify. In essence, factors to influence JND also include utility, culture and personality, which are to be highlighted as well. The talk aims at facilitating and inspiring further exploration in JND research and applications.
