VisiTrend makes powerful analysis more accessible through interactive visual analytics.

Our advisors and staff include veterans of industry, academia, and government research, with expertise in information visualization, human-computer interaction, machine learning, data mining, and software engineering. We have designed everything from web interfaces to analysis applications for neuroscience. Everyone understands the motivation for visualization, but there is a science behind designing effective interfaces that exploit human perception to reveal new insights. Our goal is to enable users to interact with interfaces that guide a variety of underlying analysis algorithms: this approach makes powerful analysis more accessible while leveraging the human user’s intuition, visual processing abilities, and contextual knowledge of their own needs.
