Of course … everyone wants a Hololens, me as well. But … what to do with it? The power of such devices is not in the device itself, it’s in the use of it. That sounds like an open door, but it’s harder than you think to come up with good ideas. Hololens is part of the More Personal Computing idea – bring computers closer to humans and make the interaction more natural and powerful.

You’ve probably seen the demo’s of Hololens. It’s mind-blowing if you think about that. And as the actual Hololens is still very limited in production (only as a developer kit in the US and Canada today), it’s almost a bit silly to think far ahead. But today we released another video with an envisioning of how interaction can get more personal. Read more

I’ve been talking to a great number of partners the past years on the topic of the Windows Store functionalities. The store isn’t just about publishing apps, but also about maintaining apps. Beta-testing is also an important part of delivering software these days, especially with the agile approach to development. Apps published in multiple languages can be cumbersome to publish – you have to enter descriptions and pictures for all those languages … by hand. Then there are partners working on multiple apps for customers. And some even produce lots of apps for others where the process up ’till now required to publish them all by hand.

During the recent //build a number of developments in the Windows Store were presented that solve a lot of these problems. Let’s have a look at a few of them. Read more

Designing UWP apps

When the Microsoft design language was introduced with Windows 8, we tried to help out with an extensive set of guidelines around design and User Experience. These guidelines were in the beginning very restrictive, which resulted in lots of apps with squares. With Windows 8.1 we explained that guidelines means guidelines, not “the law”. And although the app certification team looks at the usefulness of an app, they never disqualify an app because “it’s ugly”.

To countdown to the release of Windows 10 on July 29th 2015, I’ve created a simple countdown clock. When I was asked to do this, I first thought of a simple clock with counters, but I wanted something different. So I came up with the idea of using fridge magnets to make up the clock.

The clock is (now) always in Dutch, maybe I’ll upgrade it to also do English. You can find the app in the Windows 8 Store.

A minute is counted down visualy by the blue background that slides in or out vertically. The rest is counted down by the dynamic removal, addition and movement of magnets. All moves are done by a hand. Every now and then (at random) a random magnet almost falls off, but the hand corrects that again.

The entire screen links the the Windows 10 landing page where you can register for upgrade now or get the upgrade once it’s made available.

YouTube is a very popular video website. While this may be a good solution for public videos, it’s probably not a good solution for publishing more ‘trusted’ videos – e.g. in an business/enterprise scenario. Part of Office is Office 365 Video. This is a solution where Sharepoint is the means to store, manage and publish you company videos and Azure Media Services is the incorporated solution to make sure the videos can be played on any device in the best quality.

The wall zoomed in
Media box

I’ve published a new app in the Windows Store called MediaWall. It’s based on an idea that we used for The Voice of Holland in 2013. This app shows image and videos from a folder you select in a tiled wall. By default the wall animates so it looks like you’re hovering over the wall. The wall can show JPG, PNG, WMV and MP4 files. You can also click or tap a tile so it opens in a large media box. Tap anywhere to close the media box. In the mean time tiles are refreshed with new ones in a configured intervall.

Side-loading is a mechanism which can be used to install apps in Windows 8 without using the Windows Store. This is mainly used for Line-Of-Business scenarios. You can install an app with a developer license, but that license expires every 30 days. When side-loading is enabled, you can install an app with a license that doesn’t expire. Side-loading works on Windows RT, Windows 8 Pro and Windows 8 Enterprise. For this to work you need a side-loading key. The steps below are based on the article on Technet. Below a summary of the main steps to enable side-loading on Windows 8 that helped me set it up. Read more
