Can new technologies replace old ones?
December 27, 2011 2 Comments
In our another post One step forward, two steps back we alreasy talked about the development of the computer system from command line to GUI to touch screen. It seems that the command line was almost replaced by GUI interface in the past. In the same interview with Mr. Derboven, we asked him if he thinks that 3D interaction would be the next step after touch screen.
The answer is no.
Starting from touch screen, it could not replace all the applications we have now because it lacks the feeling of the physical feedback. As we already experienced, we can type much faster on the traditional keyboard rather than on an ipad, because we can feel where the key is. Also in a traditional keyboard mobile phone, we can type texts much faster and we can even type without looking at the screen. Although touch screens replaced most of the mobile phones despite this disadvantage, there are some devices that cannot be replaced by touch screen. For example in sports news or sport games. Normally the performance of the player will be played multiple times with different speed after the live play. By adjusting a knob on the special video machine, one can change the speed of the video. Some people wanted to make a piece of software to realize this, but they failed. The reason is when a person operates the device, he has to look at the big screen and adjust the speed of the knob in his hand to get the best play back speed, the lack of the physical contact like in software cannot do this. Or the person should look at the play screen and also the ipad at the same time, which is not possible either.
In 3D interaction, the lack of physical contact is more severe, when we are doing gestures in front of a screen, we are doing some things in the air, which is already strange to the user. Another problem is without the buttons or keys, we don’t know the gestures we do is good or not, we do not know what will happen next. The fear of using new technology is more obvious in 3D interaction.
3D interaction might be used in some specific application to enhance the physical interact or visual effect. But cannot replace anything.
