However big or small the change is, it still needs to go through this process. Alterations to the application takes time, small changes such as changing the colour of a UI element or the text that is hard coded all require a rebuild to be visible on the device. This is due to the build procedure that is run to provision the application built for multiple different platforms and device architectures. If you are working with Unity, the build time and packaging for deployment to the HoloLens 2 can be lengthy. There are negatives of having a physical device too, which is where the techniques below come in to help you overcome them. Testing your solution on a device allows you to truly evaluate everything is in working order such as parts like the user interface work well in different lighting conditions.Īnother advantage of having a device is it gives you the ability to perform user testing. This is especially true if your application has a wide use case, you want to be able to have the participants test as much as possible using the device. There may be things that are not picked up until different users interact with the UI and follow the desired use flow through the application.
This helps greatly mitigate the risks that may arise from assuming your application will work in the targeted environment.Īnother huge benefit of having a device is ‘what you see is what you get’. Having a physical device gives you access to practical testing without the need to simulate such things as the natural environment around you or the surrounding area where the HoloLens 2 will be utilized. What if you are left working on a project without the ease of access to a device? Especially at the present time with COVID-19, where everyone is working from home, sharing a HoloLens with your colleagues can be tough or not feasible. I will be discussing various topics that will aid in the development and give you an idea of concepts utilised in developing Mixed Reality Applications, In Part one of two blog posts I will cover the following: The pros and cons of device vs deviceless Unity’s build procedure for HoloLens applications Unity’s Pre-processor directives.įirstly, let’s talk about the benefits and drawbacks of both device and deviceless scenarios. Even when you have a device, the deployment time for testing can be long and repetitive. Developing for the HoloLens 2 for augmented reality projects can be quite challenging.
