"PRESI" stands for a "Pretty Simple Idea". Application development for the new generation of devices (i.e. VR, AR, smart glasses, smart watches, etc.) presents completely new challenges when it comes to computer-human interaction and security. In a nutshell, a "PRESI" is a short piece of text that brings attention to a problem and provides a pretty simple solution.
To facilitate cross-references between ideas and concepts, each PRESI will be labeled with a unique butterfly-style hashtag, such as this one: presi#bestUX
You saw a movie a few years ago with an elite person gaining access to a high-security facility. Her finger or eye was scanned, and voila, she was in. Today you're excited to see that same technology becoming reality. We're in the future. It's sexy, but...
The name for that technology, Biometrics, refers to methods that use unique body characteristics as identification: finger prints, retinal or iris patterns, face, voice, even the way someone walks (gait). It seems fool-proof. We're unique, right? Who else could gain access to my device if I'm the only one with my fingerprint?
How many times a day do you type in a smart phone password to unlock the device or an app? Surely whenever you do this, you are not always in a private setting. In present day, wearable devices like the Google glass create more problems than they solve. While you type in a password in public, such devices equipped with high-resolution cameras can easily acquire your password credentials, even from a distance. Malicious observers are already doing this and with time the risk will only grow greater. Keeping this alarming trend in mind, let's review the existing methods and approaches of how mobile and wearable devices are protected against malicious observers.
These days, there are millions of mobile applications on the market, but few can boast a great user experience. What makes an app stand out, and more importantly, who can help get it noticed?
You would think the answer would be a good graphic designer, who can draw eye-catching screenshots and innovative animations. Yet there are so many beautifully crafted applications on the market that haven't caught on, because they don't showcase an application's core functionality well. As Steve Jobs once pointed out, "Design is not just what it looks like and feels like. Design is how it works."
