Functional near-infrared sensing (fNIR) enables real-time, noninvasive monitoring of cognitive activity by measuring the brain's hemodynamic and metabolic responses. We have demonstrated the ability for non-vocal and non-physical communications through detecting directed changes in cognitive tasks. Building upon past research, this paper reports methods that allow the calibration of the fNIR oxygenation signal to better be used in more complex communicative and selection tasks. This work is then discussed in the context of a faster, continuous fNIR brain-computer interface framework.

In this paper we describe our efforts to create tangible imaging systems that provide rich virtual representations of real-world surfaces. Tangible imaging systems have three main properties: 1) the images produced must be visually realistic; 2) the images must be responsive to user interaction; and 3) the images must be situated, appearing to be integrated with their environments. Our current system, based on a computer, LCD display, light and position sensors, and graphics rendering tools meets all these requirements; supporting the accurate simulation of the appearances of surfaces with complex textures and material properties, and allowing users to interact with and experience these virtual surfaces as if they were real ones. We first describe the components of our current system and its implementation. We then illustrate the system's capabilities for simulating the appearances and behaviors of real-world surfaces. Finally we describe some potential applications of tangible imaging systems and discuss limitations and future work.

In early April, the Vanderbilt Owen Graduate School of Management Dean's Office put out a call for educational programming to be offered during the first Maymester session in the history of the graduate school. The month-long Maymester programming was designed to provide educational and skill building opportunities for students who needed to pivot their plans due to changes in summer internship, travel, and employment because of the COVID-19 pandemic. Along with faculty who provided credit-bearing Maymester classes, the Walker Management Library (Management Library) partnered with the Vanderbilt Libraries' Digital Scholarship and Communications Office (DiSC) to offer three non-credit Maymester programs. The first step was deciding on the topics for the programs.
