NACME is responsible for more than $4 million in scholarships awarded annually to underrepresented minority (URM) students, with more than $1.6 million awarded in NACME’s funded scholarships and $2.4 million more through our partner institutions’ in-kind support. NACME expects to support approximately 1,000 underrepresented minority engineering and computer students annually.
To be eligible for any NACME administered scholarship students must be either be a high school senior applying to an engineering or computer science program at a NACME Partner Institution, or be currently matriculating in an engineering or computer science program at a NACME Partner Institution, a US citizen or permanent resident, and have a minimum high school cumulative GPA of 3.0 or undergraduate cumulative GPA of 2.8 (some named scholarships may have higher GPA requirements). NACME’s mission is to increase representation of Black/African American, Latinx/Hispanic-American and Native/American Indian in the fields of engineering and computer science.

DISSERTATION RESEARCH IMPACT
The flat screens of today’s smartphones allow for integrated electronic touch sensing. Such electronic touch sensing methods are impractical to implement on non-planar rear-projection displays. This dissertation introduces a generalizable camera-based method for touch input on such rear-projection displays, allowing for touch interactions with complex virtual content registered to the surfaces. In a human-subject study, we demonstrate several advantages of this paradigm compared to others, including improved touch performance and decreases in cognitive load. We are particularly inspired by patient care: despite the importance of touch for both diagnostic and therapeutic purposes, modern high-fidelity mannequins and other patient simulators are typically unable to naturally respond to touch input, which can limit the effectiveness of training. Our research focuses on supporting touch input in a general way, making it suitable for patient simulation and other applications.

Multi-touch detection and semantic response on non-parametric rear-projection surfaces
Modern interfaces supporting touch input are ubiquitous. Typically, such interfaces are implemented on integrated touch-display surfaces with simple geometry that can be mathematically parameterized, such as planar surfaces and spheres; for more complicated non-parametric surfaces, such parameterizations are not available. In this dissertation, we introduce a method for generalizable optical multi-touch detection and semantic response on uninstrumented non-parametric rear-projection surfaces using an infrared-light-based multi-camera multi-projector platform.
In this paradigm, touch input allows users to manipulate complex virtual 3D content that is registered to and displayed on a physical 3D object. Detected touches trigger responses with specific semantic meaning in the context of the virtual content, such as animations or audio responses. The broad problem of touch detection and response can be decomposed into three major components: determining if a touch has occurred, determining where a detected touch has occurred, and determining how to respond to a detected touch. Our fundamental contribution is the design and implementation of a relational lookup table architecture that addresses these challenges through the encoding of coordinate relationships among the cameras, the projectors, the physical surface, and the virtual content. Additionally, we present and evaluate two algorithms for touch detection and localization utilizing the lookup table architecture.
We demonstrate touch-based interactions on several physical parametric and non-parametric surfaces, and we evaluate both system accuracy and the accuracy of typical users in touching desired targets on these surfaces. In a formative human-subject study, we present an exploratory application of this method in patient simulation. A second study highlights the advantages of touch input on content-matched physical surfaces achieved by our method, such as decreases in induced cognitive load, increases in system usability, and increases in user touch performance.
SELECTED AWARDS & HONORS:
2012, UCF Presidential Doctoral Fellowship
2018, IEEE Virtual Reality Doctoral Consortium
2018, Graduate Travel or Presentation Fellowship
The Ada Lovelace Fellowship is a new fellowship for Microsoft Research, established to support diverse talent getting doctorates in computing-related fields by providing three years of funding for second-year PhD students from groups underrepresented in computing.
“My hope is that the Ada Lovelace Fellowship will inspire an abundance of unconventional problem solvers and thought leaders—those who don’t fit the mold but who are excited to address challenges in their respective communities and global society,” said Divine Maloney of Clemson University.
Maloney’s research seeks to understand the role of implicit biases in embodied virtual avatars and to establish guidelines to minimize unwanted biases in the design of avatars and other immersive virtual reality content.
“There is no single factor that will make VR adoption go critical mass,” says Professor Gregory Welch, chair at the University of Central Florida College of Nursing. “The US military has just bought $100m of HoloLens units which it is using for training and UAV [unmanned aerial vehicle] surveys. It is also being used to train medical professionals in childbirth. AR has been around since the 1960s and the technology is improving all the time. When the hardware can be packaged like eye glasses, I suspect people will be more comfortable, but it still lacks a killer app.”
