Two rounds of comfort and fit studies were executed to examine perceived comfort, fit, and stability during prolonged wear for concepts of AR glasses. In a separate study sequence, MUS captured robust and reliable data on possible use cases and features under consideration that will have the highest desirability, value, emotional resonance, and promote subjective well-being for the projected user group.

Eye-tracking, micro-facial expression analysis, and galvanic skin response data capture were utilized in addition to survey response data capture throughout the overall research program. Survey questions for the feature set validation study sequence were based on subjective well-being research literature.

Executed an applied cognitive task analysis (ACTA) to assess how the benefits of an enabling technology for thoracolumbar decompression and fusion spine procedure outweigh the risks from the perspective of 8 non-biased surgeons.

The ACTA also aimed to improve understanding of cognitive skills, expertise, strategies, judgments, and decision-making required for each of the tasks/subtasks involved in the computer-aided surgery, as well as determine whether the enabling technology effectively reduces cognitive and physical workload for surgeons. Opportunities for optimization of the enabling technology were also captured and reported.

MUS developed and validated the first fully integrated neuroscience-based human factors and ergonomics testing platform for video game systems. The testing platform captures 29 channels of real-time psychophysical, cognitive, and ergonomic data integrated into a unified data stream. Read More
The system utilizes proprietary combinations of 3D spatial tracking, micro-facial expression analysis, galvanic skin response, high-performance eye-tracking, 3D model generation, and several dimensions of actual live video gameplay key performance indicators.

Executed a study to understand the impact of drug viscosity and volume, as well as PFS device physical parameters (e.g., finger flange extender, plunger design, barrel design) and injection location on acceptable injectability. Also, examined the distribution of force during plunger press down in x, y, and z axes to understand the extent of off-axial force exhibited by representative users. A tri-axial force measurement platform was custom-developed for this off-axial force assessment.

Executed two studies to inform the device design and related IFU for an opioid overdose drug. High-performance eye-tracking was employed to gain robust insights into how addiction clinic personnel and first responders interact with the device and IFU and apply information gathered from the IFU to perform all tasks necessary for successful drug administration. 

Executed a rapid response agile IFU redesign for a complex multi-vial adapter system to effectively and efficiently resolve critical error patterns leading up to formal FDA validation. Eye-tracking was employed to understand user visual attention distribution / information uptake for each IFU iteration tested and inform modifications moving toward the final validated IFU design.

Conducted a series of studies examining high viscosity intravitreal drug delivery optimization with multiple pre-filled syringe device concepts. A high-fidelity intravitreal (eye-injection) injection simulator was custom-designed for these studies. Retina specialists and ophthalmologists were sampled.

Conducted extensive formative and summative studies for submission to FDA including 3D micro-motion and EMG testing for determining device manipulation and needle pain in the use of consumer drug delivery devices.

In a multi-year engagement, executed international UX design, usability research and user engagement optimization programs for Citibank online services. Reported to the highest levels of the bank including Office of the Chairman. Developed primary interaction framework for Citibank home banking utilized on a global basis. Conceptualized and developed large internal teams of subject matter experts, HFE staff and related testing facilities. Citibank online customer experience rated number one on a global basis during period of involvement.

Executed Complex Information and Decision Analysis for a Very Large Data Set of Highly Divergent Investment Funds. Designed and Tested New UX / HCI Information Display Platform Focused On Providing Rapid Visualization of Fund Status by the Board and Trading Departments.

Executed complex human factors engineering research and workstation / user interface (UI) design programs resulting in the creation of a new generation of mission control launch centers for NASA Space Shuttle operations.

Executed Advanced Neuroscience-Based Research to Aid in UX Optimization and Brand Enhancement of Whitney.Org and Related Web Presence

In a multi-year engagement, MUS executed business-critical human factors engineering research and complex user interface design programs resulting in the creation of a new generation of screen-based (fixed and hand-held) trading systems that dramatically improved trading performance, reduced training time and reduced errors. Solutions verified by independent usability testing. Core concepts implemented by other major exchanges and trading platforms worldwide. MUS received Interactions Design award from Association of Computing Machines for this effort.

Conducted formal ergonomic analysis of subminiature production processes, workstation design, process design, production of advanced ergonomic workstations, and support tools. Also executed worker longevity predictions based on workplace optimization data.

Conducted extensive ergonomic and user prefererence testing for advanced consumer product concepts including application of robust 3D manipulation analysis, EMG testing, and large-scale market segmentation analysis.

Conducted various confidential research programs spanning 3 decades.

Conducted extensive usability testing, UX optimization research, and UX design for series of critical DOD web interfaces for military personnel and DOD operational staff.

Conducted multi-year longitudinal usability testing and UX optimization research for multiple primary MTV media properties. Applied advanced cognitive modeling methods in optimization of teen interactions with new media sites.

Complex Total User Experience Optimization (TUXO) Analysis of Portal Music Devices and Online Music Acquisition Systems

Conducted extensive usability and information transfer analysis of online content categories and presentation formats focused on defining information structures that had the greatest impact on clinical outcomes of cancer patients.
