On Brain Size, Intelligence And Food

Friday, March 21st, 2014

How many neurons does a human brain have? Are larger brains smarter brains? Do larger brains have more neurons in them? Does the size of a brain increase with the size of the animal? How much energy does a brain consume, and why is this important? Are there limits to how many neurons a brain can contain?

These and many other questions are tackled in this particularly informative TED talk. Take a look:

Visualizing Imagination

Friday, March 21st, 2014

What do you do when you have an idea? How do you think about it? If you’re like me or like most people, you probably imagine this idea in terms of visual images. Irrespective of what the idea is, be it an object, a plan for doing something, or an abstract concept, the first tendency is to try and view it in some way. You are basically doing a “rapid mental prototype” of your idea or concept.

Now imagine how could it would be if you wouldn’t need to learn to draw in order to get these images out of your head in an almost 1-to-1 mapping. Yes, these days are not far away and brain scanning makes it all possible. Just take a look:

If we will be able to extract the images and the sketches from our heads, simply by imagining them, what would this mean? The potential implications are endless: drawing by thought, getting ideas quickly to paper, recording dreams, and many more.

So what would you do if you could get your mental images on paper?

The Building Blocks Of Interaction

Friday, March 21st, 2014

What makes interaction intuitive? And why are IT systems so dependent on the one screen paradigm?

The Siftables tangible user interface shows us that there are alternatives. Do you see such interaction being used in a wide range of applications? Or are such specific approaches damned to serve their purpose as pure toys and learning aids?

Arguments In The Snowden vs. NSA Case

Friday, March 21st, 2014

In case you haven’t heard, in the last week or so, TED invited Edward Snowden to give a talk at TED 2014. At the same time, they have given the NSA the opportunity to react to any of the information provided by Snowden. The final results are two talks, showing the two sides of the story:

Which side are you on?

First There Was Touch, Then There Was Handwriting

Friday, February 28th, 2014

For decades we have used keyboards to communicate and express ourselves in the digital world. Relatively recently, the focus of user input has shifted towards multi-touch interaction, at least for a select group of devices and tasks. Now it seems that handwriting is about to get a boost in the virtual space.

Wacom is releasing a cross-platform standard for sharing handwritten notes and drawings. This is even more impressive when we consider that users will be able to experience and interact with how their collaborators are sketching something or writing a note. Imagine sitting in your hotel room with your tablet in your hand, while watching in real-time how your child creates a drawing on his device at home. Technology is getting increasingly focused on the human factor, and I believe this is the exact way to follow.

The Curency Of Social Media Is Envy

Wednesday, October 23rd, 2013

The complexities behind jealousy and envy, and how it really is only a matter of imagination run amok.

7 Years Of Cernea.net

Thursday, September 19th, 2013

Seven years have passed since the first time the cernea.net website came online. Sure, I had a small site even before that, but in 2006 I decided that I needed a new look, a blog and my own domain. And frankly, the site went through many changes since back then, growing in complexity as I opened up new chapters in my life.

As a semi-nostalgic commemoration, I wanted to show you how my website looked in 2006:

DJ Mind – All The Songs Are In Your Head

Sunday, September 15th, 2013

This is what happens if you enable DJs to mix not with their hands, but with the help of EEG neuroheadsets that record their brain activities and interpret these signals as commands for mixing a song.

The Map Of Minimum Income

Sunday, September 15th, 2013

I found this to be an interesting representation of the minimum income levels in Europe. Not how some countries don’t have any legislation to establish a minimum income.

It’s All In The Hands

Friday, September 13th, 2013

Where’s a video with the people who are also working on the Tesla Model S, the famous electric car. It shows how companies like Tesla try to improve their efficiency by embracing novel technologies, like mid-air interaction, augmented reality and 3D printing.

By the way, when will I get my chance to play with a 3D printer? The CAD model is already prepared. 😉
