The WSI Way – WSI’s CTO Håkan Ohlgren on the GameFace case

This is how WSI works with GameFace Labs. Håkan Ohlgren, WSI’s CTO and Chief Architect tells us.

WSI_GameFace_X2_01What role did WSI play in the project with GameFace?
– We were contacted by GameFace Labs in 2014 to develop a new generation of their VR-headset. Our assignment was to create a complete headset incorporating electronics, Software and mechanics. GameFace Labs created their proprietary home screen and some very specific software, while WSI implemented an Android port for the NVIDIA® HW platform. GameFace Labs also paved our way to NVIDIA®. We based the design on their Tegra K1 which is a very capable Application Processor with superior graphics performance. We partitioned the system so that the heavier batteries are kept in a belt clip device, connected to the VR-headset through a cable. That is the only cable in the system. In order to re-use the legacy user interface of Android, we implemented a capacitive touch pad on one side of the headset. The headset includes Wi-Fi connection (802.11.a/b/g/n) to internet and Bluetooth connection to wireless input devices such as gaming controllers, mice or keyboard. The Wi-Fi connection means that Applications can be downloaded and the FW can be updated wirelessly. GameFace Labs has implemented a novelty way to speed up Application download. It is truly remarkable how fast applications are started upon a download! We implemented 2x2MIMO (antenna diversity) for the Wi-Fi transceiver in order to make fast and robust connection to the network.

How was the collaboration with NVIDIA®?
– We’re a relatively small company. Big companies like NVIDIA® normally has no or very limited capacity to manage small customers, due to resource constraints. But NVIDIA® liked GameFace Labs concept and decided to use WSI as a design house, under the agreement that we would get minimal support. We managed to do the design ourselves, with some valuable support from them, which I believe contributed to NVIDIA® wanting to make us an official partner. We showed them what we are capable of. Now they submit clients to WSI, which we are very proud of. The GameFace project was the starting point of our partnership.

How did WSI work internally on the GameFace project?
– It went very smooth. We’re a company of team players where everyone pitches in. The collaboration between the project manager, the system architect, the HW and SW designers, PCB layout, Industrial designer and the mechanical designer went truly well. We called in two external Android experts when needed. In addition to our own organization, our extensive network is one of our greatest assets.

What were the greatest challenges?
– Probably the power and heat management. Unlike other VR glasses, everything is built into the headset. The NVIDIA® Tegra K1 is extremely capable and scalable. In the GameFace Labs VR-headset a superior graphical performance is required. But this comes with higher power consumption which consequently generates more heat. We needed to implement an active cooling system in the headset, using a silent fan with a heat pipe that transports the heat out of the headset. This keeps both the electronics as well as the user cool. The latter is important as the battery and power system is capable of many hours constant use, and the overall user experience is extremely important.

In addition to the technology, what are the strengths of this project?
– We persevere together with our clients, even if the financial situation becomes instable. We want to help our clients all the way to the finish line. I think the reason for our success is that we are all team players through and through.

The Swedish electronic design company WSI (Wireless System Integration) joins the NVIDIA Jetson Partner Ecosystem

WSI, a Sweden-based embedded hardware company, announced today that it has joined the NVIDIA Jetson Embedded Platform ecosystem and becomes the first company in the Nordic region to earn Partner status from NVIDIA, the world leader in GPU-accelerated computing.

The competence of WSI within wireless technology along with the power and performance of NVIDIA’s processors is a formidable combination. NVIDIA Jetson is the world’s leading visual computing open platform for GPU-accelerated parallel processing in the mobile embedded systems market. Its high-performance, low-energy computing for deep learning and computer vision makes Jetson the ideal solution for compute-intensive embedded projects.

WSI has already developed several products, including the mini-computer Solu, which launched this year. WSI also played a major role in the development of the virtual reality 3D headset from GameFace Labs.

“WSI is focused on creating innovations for the future. Our strength builds on global, long-running networking and cutting-edge expertise in wireless technology. It will be our ace up the sleeve when the VR and IoT-boom blooms to its full extent,” said Jan-Åke Lindqvist, CEO of WSI.

“The NVIDIA Jetson platform offers great performance in a small power envelope,” said Serge Palaric, Vice President of Sales for Embedded and OEM in the Europe, Middle East and Africa region at NVIDIA. “We’re excited to see the new products that WSI is bringing to the embedded computing ecosystem.”

Companies are invited to join the NVIDIA Jetson Embedded Platform ecosystem program based on meeting the exact specifications of the Jetson Embedded Platform, including mastering CUDA and reaching NVIDIA’s excellence standards.
