    The Feasibility of AgileNudge+ Software to Facilitate Positive Behavioral Change: Mixed Methods Design
    (JMIR, 2024-11-13) Shojaei, Fereshtehossadat; Shojaei, Fatemehalsadat; Desai, Archita P.; Long, Emily; Mehta, Jade; Fowler, Nicole R.; Holden, Richard J.; Orman, Eric S.; Boustani, Malaz; Medicine, School of Medicine
    Background: In today's digital age, web-based apps have become integral to daily life, driving transformative shifts in human behavior. "AgileNudge+" (Indiana University Center for Health Innovation and Implementation Science) is a web-based solution to simplify the process of positive behavior change using nudging as an intervention. By integrating knowledge from behavioral economics with technology, AgileNudge+ organizes multiple steps, simplifies complex tasks, minimizes errors by enhancing user engagement, and provides resources for creating and testing nudge interventions. Objective: This paper aimed to outline the design process, methodologies, and usefulness of "AgileNudge+" for the development of evidence-based nudges. It used a mixed methods approach to evaluate the software's interface usability and usefulness for creating and testing nudge interventions. Methods: AgileNudge+ was developed through iterative processes integrating principles from behavioral economics and user-centered design. The content of AgileNudge+ operationalizes an Agile science-based process to efficiently design, embed, and disseminate evidence-based nudges that encourage positive behavior change without limiting choice. Using a mixed methods approach, we tested AgileNudge+ software's ability to organize and simplify the nudge intervention process, allowing a diverse range of scholars with limited knowledge of Agile science to use nudges. Usability testing assessed the tool's usefulness and interface with a sample of 18 health care professionals, each asked to interact with the software and create a nudge intervention to solve a problem within their professional project's sphere. Results: The study was funded in August 2022, with data collection occurring from June 2023 to July 2024. As of July 2024, we have enrolled 18 participants. Quantitative results found a mean usefulness rating of AgileNudge+ of 3.83 (95% CI 3.00-4.66). Qualitative results highlighted ways to modify the language used in AgileNudge+ to be more comprehensible to a diverse user base and promoted modifications to the software that facilitate real-time assistance and prioritize time efficiency in user interactions. Feedback further supported the positive impact of gamification on participant motivation when using the software. Conclusions: AgileNudge+ is an effective assistive tool for simplifying the positive behavior change process using nudge interventions, with tailored content and interactions to meet users' needs and demands. Building onto the current design, future iterations of AgileNudge+ will use artificial intelligence to process large volumes of data while reducing the time and mental energy required to scan for existing cognitive biases and nudge prototypes. The software is also being upgraded to build on current gamification efforts, encouraging more sustained motivation by increasing the temporal resolution of the digital interface. These modifications stay true to the agility and user-centered aspects of AgileNudge+, emphasizing the novelty of the constantly evolving software design process.

    Themed Entertainment Impact Adapter Senior Design Final Report
    (2023-05-03) Landis, George; Freeh, Ryan; Pash, Phillip
    This project is what is known as the Themed Entertainment Impact Adapter. The issue is to improve a system already in place by creating a new detection system that will allow a guest to interact with set pieces with a physical hit and have communication back to the host. The sponsor, IFM Interactive, is wanting a custom Printed Circuit Board (PCB) that will be housed in a watertight plastic case specified by the sponsor. The device is a detection system that uses an accelerometer to notify another unit that the device detects a spike in the z-axis direction. The specifications that needed to be met that were given by the sponsor are as follows, • Printed circuit board-based design that mounts inside of an IP rated enclosure selected and provided by the customer. • Enclosure penetrations must retain environmental (IP) ratings such that the device could be installed outdoors. • Capable of operating in temperatures up to 80C. • Accept 5VDC for power. • Communicate via half-duplex asynchronous UART over RS-485. • Connect to upstream power and RS-485 data via a single 4 pole M8 connector. • Detects forces applied via internal accelerometer. • Implements communication protocol specified by the customer. • Create ~6 fully working units by April. The test plan is to test on a similar board using an RP2040. We will want to make sure that it sends a signal using UART over RS-485 to a computer emulating the host machine. The results have been successful in testing. There have been issues with the actual device that are minor fixes in the software design than the hardware. The final system will meet the standards from the sponsor. Some recommendations on improvements would be a better implementation of the hardware. Thus, there is just a bit more of editing on the layout. Moving the USB-C to another open way to make way for the port that will be drilled out of the unit to allow for access to power and data to the upstream unit.
