Feel what you see

ET — Sun, 27 Oct 2013 22:19:48 +0000

Would be nice to test this technology which lets you feel surfaces of displayed images. I would like to know how realistic it can be.

Mapping virtual to real movement

ET — Wed, 22 May 2013 20:09:11 +0000

A person is walking through different virtual rooms while in reality doesn’t notice that he walks in a nine by nine meter space only. To the person, the virtual space seems to be larger.

Are we talking about the same color?

ET — Mon, 18 Feb 2013 17:11:10 +0000

It turns out, many people questioned if their color perception is the same as the perception of others. Let’s say as a child you saw something and e.g. your mom told you this is a red strawberry or some other thing is a yellow banana. So you got the idea of red and yellow.

But that does not mean the interpretation of your visual informations in your brain and the interpretation of your mom is the same. And no one knows…

Augmented vision

Seems as TV is going to be extended to stimulate our peripheral vision.

Electro-impulses instead of glasses

ET — Fri, 04 Feb 2011 22:00:01 +0000

That’s funny!

But can this be true? To trigger a blink of an eye with mini ‘electro-shocks’ to the temple, that’s possible in my opinion. You need at least 25 blinks / electro impulses for each of the eyes. That’s also feasable, I think. (I don’t know exactly if this is really enough but it has to be the minimum!) But when I try to blink with my eyes as quick as possible everything is getting dark. The amount of time I closed my eyes is bigger than the time I have my eyes open and the ‘open time’ isn’t long enough to process the content / images. So in my point of view this video is funny but not more.

Third eye in the back of the head

ET — Fri, 14 Jan 2011 22:00:56 +0000

In the name of art the New York University professor Wafaa Bilal had implanted a titanium connection base for a magnetically camera in the back of his head.

That’s a really nice thing for new use cases. For example think about hacking at the computer in the front and watching TV in the back. *fun* But seriously you can have more overview while walking in dark streets. I’m sure this is very interesting for military purposes.

The questions are: Is the human brain able to process this third eye? Actually W. Bilal is looking at the video data with his own two eyes via laptop. But what if one connects the camera with a brain computer interface directly with the mind? Why didn’t do nature such things? Is the human going crazy because not knowing where he is going (forward or backward)? Is this a new step towards cyborgs?

Touchless multi-touch in 3D

ET — Sat, 17 Jul 2010 12:00:45 +0000

As I wrote some time ago, human-machine interaction is going towards the interesting trends we saw in futuristic films years ago. Here is another example of a human-machine interface which reminds us particularly of “Minority Report”. A man is gesticulating with both his hands free in space and on a screen you can see a 3D scene performing appropriate actions.

That’s impressive!

—

But because I’m seeing some disadvantages with this technology for me it isn’t such impressive anymore. The disadvantages or let’s say challenges are:

One has to hold his arms continuously in free space, for sure that’s exhausting.
What if there are more than two hands / one user? Are the algorithms able to match the hands to the right persons or will there be false recognized (inter)actions?
In my opinion the user gestures were adapted to the technology not to real user needs / perceptions.
The actions are not accurate enough yet.
In the case of the deletion of files some other way would be much better than to move the files to the edges I think. Because this action suggests me that there will be a backup of the files and I#m able to load them again.

And beside the other details a main goal for future investigations has to be to remove the need that a user has to recheck visually what he is doing with his hands (red cross and borders in the video and so on). The user wants to e.g. translate a picture, commands that with his hands and that’s it. The extra necessity to visualize that destroys the / my sensations.

But the technology (free hand gestures and 3d scenes) is a really great step into future!

Do you believe in UFOs? Unimaginable?

ET — Sat, 03 Jul 2010 12:00:21 +0000

Here is an amusing video about “beliefing (or not) in UFOs” which shows our boundaries of imaginative power and that optical illusions should be known as brain failures.

In my opinion we have to recognize these things “mental / perception problems” when designing human machine interfaces, in a way that new technology doesn’t confuse the users.
