ATTENTIVU HOLOLENS ATTACHMENT

2019 - 2020

In this project we propose a prototype which combines an existing AR headset, Microsoft's Hololens 2, with a Brain-Computer Interfaces (BCI) system based on our AttentivU project, and we perform several tasks to validate this concept.

The first application is built around the idea of enhancing the creativity of the user, where a user imagines an object and the object appears in front of him on the screen of their Hololens 2. In the second application we investigated the feasibility of using a BCI based on covert visuospatial attention – a process of focusing attention on different regions of the visual field without overt eye movements. We operated without relying on any stimulus-driven responses.

In the final application, we investigated underlying attention changes and response time of the user which could be used as indicators of specific characteristics of brain activity in pre-frontal cortex following the research in hyperscanning and individual differences using BCIs.

The proposed system is, to the best of our knowledge, the first AR-BCI integrated prototype that uses covert visuospatial attention and visual imagery for a total cost of components under $1000 -- much more affordable in comparison to previously published prototypes that use AR headsets and BCIs.
