In this deliverable we present the first version of the experience capturing hardware prototype design and API architecture, following on from D3.1 and the final selection of sensors. This deliverable involved acquiring, testing and integrating the various off-the-shelf sensors and developing a hardware/software design to connect the various devices and sensors into a single platform. This also involved solving problems around how we would manage the additional computing power, storage and wireless streaming capabilities required for this project.
In this first version of the deliverable we propose an initial design for the hardware and architecture and have focused initially on providing a bare-bones prototype of the Sensor Processing Unit which involved combining a micro-pc with various sensors to test the flow of data, capabilities of the system and possible connection methods to the device for the various sensors.
The first hardware prototype does not yet include the wearable element, however, our selection of the sensors and micro-pc takes into consideration the desire to integrate the hardware using 3D printing or by creating add-ons for the Hololens to avoid a chunky or multi-device hardware solution. We have provided a mock-up in the Prototype and Usage Descriptions section below of what the final prototype is expected to look like.
As described in D3.2 although there are other AR alternatives already available in the market, they all fall short in terms of the required spec and functionality. A decision was then made to work with the Hololens as it would be the best in class and although not available has been tested by key partners and will be available in time for the next deliverable.
Within this deliverable we also provide an initial mock-up of the hardware design and also a sample of the API and links to device APIs.
