OptoFidelity Product Performance Excellence - Resolve performance risks before they appear

By OptoFidelity on 8/28/20 1:49 PM

We ensure the reliability, responsiveness and consistent performance of your product, all vital for the success of your brand. We can integrate performance test engineering into your mass production process to discover bottlenecks and challenges before and during the production.

Gain end-to-end system performance visibility with our shift-left approach

In a Shift-Left approach, testing is performed during the early stages of product design by moving to the left in the project life-cycle. Developers need to focus on quality from the beginning, instead of waiting for performance issues and defects to be discovered late in the development life-cycle. Shifting left enables project teams to test, provide feedback, and review changes & progress daily.

Display Color Measurement -Background and Applications

By OptoFidelity on 3/13/20 9:00 AM

Display Color Properties

Displays of all kinds are the main channels for human interaction with various devices. Whether it is a mobile phone, tablet, PC, cars, home appliances, info screens, or machine controllers, displaying information and content on display is the most natural way to interact with people. As the variety and usage of displays increase, the color optics of display performance grows in importance. Can the user see the content clearly from various angles? Are the colors vivid and natural at the same time? Are there unevenness or visible defects on display? Do the colors of two in-device displays match when it comes to dual-screen devices?

Why Touch is to be tested?

By Chinmay Zare on 2/24/20 9:00 AM

Humans are gifted with five senses namely sight, hear, touch, taste and smell. These senses help us perceive the world and get the best of the experiences. Technology has certainly adapted to give us best experience by the means of touch. From phone to a watch, from car to fridge, from ATMs to POS, everything is embedded with a touch capacity for human interaction. Delivering such interactive technology comes with a requirement of quality assurance to keep the product consistent and enhance the customer experience. Having shipped a poor quality of touch panels in any device has a significant impact on the quality of device. This certainly affects the device brand and the future of the product. Having a thorough testing cycle in R&D as well in manufacturing line, improves the quality of production, which helps getting better business yield.

Comparing VR headsets’ tracking performance

By Pekka Laiho, Tommi Nikula on 1/20/20 9:00 AM

Consumer VR headsets have been available since 2015, when a large number of companies announced their own versions of the products. By 2016, more than 230 companies were working on their own VR HMD projects. Most of these projects have since ended and companies have gone bankrupt, but some keep releasing new products, both stand-alone and tethered versions, on an almost annual basis. Oculus (Facebook) released new Quest and Rift devices in 2019, while HTC came up with a new VIVE and Valve announced their Index glasses. Then there is Varjo, a company that keeps amazing their fans with human-eye resolution products, as well as numerous new Chinese companies that are also catching up fast in product design and performance. In CES 2020, there were dozens of new players and products coming to both the VR and AR markets. [1] [2]

Smart Device Testing

By Jere Paloniemi on 12/14/19 5:27 PM

Smart devices are electronic devices which integrate various sensors and actuators which enable product features. Smart devices are generally connected to other devices or networks and can operate to some extent interactively and autonomously. Development of a smart device starts from component and technology selection and continues with product R&D, manufacturing and after sales. End user experience is the key differentiator for any smart device product. It is built from well performing components and skillfully integrated product hardware and software.

Summer with cool robots – stories by our Summer Trainees

By OptoFidelity on 9/17/19 9:00 AM

Each year we seek enthusiastic, bold and open-minded Trainees to join our troops. This summer was no different and we were excited to have overall six new OptoFidelitians. We promised that these Trainees will have a summer with cool robots, awesome colleagues and unique projects – how well did we succeed with this promise? Let’s find out from the authors themselves: Sini, Joonas, Olli-Pekka, Ismo and Juho!

Sini and Joonas, you worked as Software Trainees, what did you get to do here?

Sini: During the summer I got to do a lot of work directly related to my education and interests. This was the most important thing for me, since as someone mostly focused on users, UX and UI design back-end coding is not inspiring to me. I was surprised how much people here were eager to hear my opinions and how much those really affected the outcome of the projects.

I designed and made prototypes of a few user interfaces and got to develop one from start to finish. In the university I hadn’t learned a lot about UI programming and the experience from here is patching up important holes in my know-how.

What really made the summer enjoyable here was my project team. The average age of the team was probably somewhere in the mid to late twenties, which helped us connect and have fun too on the side of work. I look forward to continuing as a part-timer when I start my studies again!

Novel HMD testing technology – Optical measurement of VR headset tracking performance

By OptoFidelity on 10/11/18 9:00 AM

OptoFidelity worked in co-operation with University of Jyväskylä, Department of Physics. Our co-operation was related to academic research in the area of HMD testing technology. Our interest was to find new optical measurement technologies and methods for VR headset tracking performance. As an end result, we developed a novel technology for testing HMD´s. If tracking performance of HMD is poor, it will effect drastically to end user experience. OptoFidelity has been working with user interface testing for years. As HMD´s are getting more and more popular, we believe better testing technology is needed as well.

Reverse logistics of smartphones – our experiences in refurbished smartphone testing

By OptoFidelity on 8/30/18 4:26 PM

Refurbished smartphone testing is not possible with traditional testing approach. Novel technology and thinking is needed in order to overcome the challenges. Especially you can see the problem, when you are trying to automate Android functional testing for refurbished phones.

There are 2.3B Android smartphones in use globally (*). And more and more smartphones are getting a second life as well. This means reselling the phone to another user when the primary user wants to get an upgrade. This reverse logistics business requires testing as well. If you want to sell it with a good price, the phone must work well.

Why is VR HMD not yet rocking the world?

By Wen Nivala on 3/28/17 3:33 PM

Virtual reality (VR) allows a person to interact with a three-dimensional image or environment through the use of display, optical and sensor technology, in connection with powerful graphics and CPU. Wall Street has high expectations for the market potential of VR; much depends, however, on the results in the sales report. I would like to discuss the reasons behind the figures of the User Performance (UX) of VR HMD. However, this is not a formal study but rather a light recollection of personal experience, observations and interviews.

SLUSH HELSINKI 2016, VIRTUALLY YOURS

By Kimmo Jokinen on 12/5/16 3:14 PM

After I have been chewing over the SLUSH experience for couple of days, I can align that the leading start-up event in Europe was an overall positive experience for a first-timer. The event is not only about matchmaking for start-ups and financiers, but it has become “the event” for high tech companies in particular, where you can find first-rate presentations, discussion and networking opportunities all in one. Maybe it’s because the event is intended for start-ups, but the entire SLUSH population is open and ready to listen to what others have to offer. Everyone is a potential partner for your business, one way or another. This open willingness to communicate makes the event stand out among ordinary trade fairs.
