Supporting, rather than undermining, human attention and cognition is critical in high-stakes environments.
Details: ENKIx is the acronym for Enabling Knowledgeable Task Guidance In the Extremes. This DARPA-funded effort targeted augmenting human cognition by developing an assistive system powered by AI that can guide users through procedural tasks. The essential capability of the system to understand the task, when to provide guidance, and what guidance to provide is just one of the many research challenges we are studying on this project. “Extreme” in the title refers to the extremes of human task performance, including high hazard and risky operations under harsh and high-demand environments. The system is designed for augmented reality (AR) headset technology. Dr. Jaime Ruiz of the Ruiz HCI Lab is the lead investigator heading up a large team (see below).

The INIT Lab, in conjunction with the Ruiz HCI Lab, have been working on:
- Creating the AR app
- Designing the interface that the user will see, using a user-centered design approach
- Tracking the state of the world (where objects are in the AR)
- Voice and gesture input
Other teams at UF and associate performers are working on:
- Task representation: the state of the task and what steps are not yet completed
- User modeling: determining user’s cognitive and physical stress levels, and knowing their skill level
