abstract = "The objective of our study was to evaluate usefulness and effectiveness of Human Centered GeoVis prototype{"}The SanaViz{"} against a conventional GeoVis application Instant Atlas. The SanaViz is an interactive, internet based application aimed at facilitating visual exploration of public health data, and in this context telehealth data from Brazil. A cross sectional, within-subject, mixed methods study design was utilized. A convenient sample of 20 study participants from diverse backgrounds was enrolled. The users were asked to perform 5 tasks using both the GeoVis applications. Univariate analyses were performed for continuous and categorical variables. Repeated measures of analysis of variance was performed on the within-subject design to test for significant differences between {"}the SanaViz{"} and Instant Atlas. All analysis was performed using SAS v9.1. Results showed that {"}The SanaViz{"} required less time, less assistance and fewer attempts and was reported as easier than Instant Atlas.",
