Title: Innovations by Roger Hau

Introduction

Roger Hau is an accomplished inventor based in Seattle, WA, known for his contributions to data visualization technologies. He has been awarded three patents that showcase his expertise in creating methods for generating visual representations of data. His work primarily focuses on enhancing the way data is interpreted and presented, making it more accessible and understandable.

Latest Patents

One of Roger Hau's latest patents involves a method for generating data visualizations according to an object model of selected data sources. This method receives a visual specification that outlines a data source, visual variables, and data fields. It identifies a minimal subtree from the object model that includes all dimension data fields and constructs a query to retrieve a set of tuples. Each tuple represents a unique combination of data values, and the method forms extended tuples by appending aggregated data values for measure data fields. Ultimately, it builds and displays a data visualization based on these extended tuples.

Another significant patent by Hau focuses on using an object model of heterogeneous data to facilitate building data visualizations. This process also begins with a visual specification and identifies sets of dimensions and measures. It aggregates values of measures according to the dimensions and constructs a data visualization that aligns with the specified visual variables. These innovations reflect Hau's commitment to improving data visualization techniques.
