The topic of 3D is on everyone’s lips: no exhibition space, a German electronics retailer does not need the new TV generation.
Apart from the trendy term is now also in other consumer electronics devices have become the driving force: Since there are digital cameras with 3-D panorama and now even laptops with 3D screen. The latest craze in the industry: 3D smartphones. In this category so far are the 3D models of LG and HTC Evo 3D Optimus appeared. Both smartphones feature a dual-lens camera that can record videos and snapshots in spatial quality.
What sounds like a technological breakthrough, but in practice clearly harmless: The resolution of the images is the three-dimensional effect is reduced significantly so that the function of at most a certain “wow factor” brings – but nothing more. However, it is assumed that the manufacturers are already working on next-generation 3D smartphones.
The journal “Journal of Vision ‘reported for the first time by an appropriate study that deals explicitly with the new generation of smart phones and similar devices, 3D and their impact on the senses. It was found that the problems experienced volunteers to focus on several levels simultaneously. Specifically, it is necessary in the performance of three-dimensional content, almost simultaneously, one for the light source (in this case the phone) and the other is the image projected by it, which is located in front or behind to look at.
In this capacity, the human eye is not really aligned so that the attempt by many to discomfort in the form of fatigue to headaches and in extreme cases leads even vomiting. Furthermore, the study showed that encumber the short distance perceived 3D images (smart phones, digital camera-control displays, computer monitors), the human brain less, if they occur on a rear plane, practically behind the display. In a situation of conventional television and cinema in the 3D contrast, the subjects found it more pleasant if the images produced before the panel or the canvas.
To make matters for some consumers, the so-called “Motion Sickness” added. It is a neurological syndrome that was originally brought to the enjoyment faster 3D games on the computer together. In a modified form of the disease may also occur when viewing 3D images occur: because the image is sent each for the left and right eye, slightly modified, must be “put together” the brain of both channels. In the course of this creates the desired 3D effect. Also, motion sickness can cause headaches and nausea.
