With the rise in technological advancements, we have seen a general decline in the use of conventional means of performing certain activities. The typewriters have been taken over by keyboards and the postman’s job has been made easier with the ability to send one’s messages over the internet.
One of these modern-day inventions was the smartphone. Smartphones completely changed how human perceived and interacted with technology on a daily basis. The people of today perform all those activities on their smartphones that they would on their computers, because smartphones provide you with all those opportunities but in a much smaller and portable device.
Another iteration of the smartphone was the tablet. These large-screened devices made it easier for people to take their whole world with them wherever they wanted. Typing emails, watching movies or just passing one’s time became more immersive on a tablet than on a smartphone. Where tablets have made use of the laptop screen quite redundant, now they might be able to take over conventional reading material as well, including books and magazines, thanks to Professor Brian Barsky of UC Berkeley.
Professor Barsky has designed a tablet screen which has the ability to make the content look sharper to people with optical deficiencies. Making use of complex algorithms, this screen will be able to adjust the amount of light it emits in order to help people see content more clearly without the need to take out their reading glasses.
While conventional cases of weak eyesight can be tackled with the use of lenses, there are some diseases that cannot be controlled so easily. Presbyopia, for example, is a condition in which people lose their ability to focus on objects near to them with the increase in their age. Other conditions, known as high order aberrations, which are caused due to irregularly shaped corneas do not allow a contact lens to fit the eye, and are thus difficult to handle.
The professor has designed this display especially for these people, who may suffer in other aspects of life as well due to these irregularities. For example, one may not be able to get a job because they would not be able to look at a computer screen all day with their complicated visual condition.
Deconvolution to Alter the Display
The basic idea behind the display is that the images are distorted in a way which makes them appear sharper to a person with bad eyesight. This is done with the help of a display that has two layers of clear plastic with a printed pinhole screen in the middle.
The pinholes have a distance of 390 micrometers between on another, and are 75 micrometers each in size. This allows the light that comes out of the screen to be controlled at the smallest of levels. The intensity of each ray of light emanated is controlled based on specific users, which ultimately leads to an image distorted in a way that appears to them as being sharp.
The idea to alter the screen’s content itself to make it look sharp is quite interesting. The professor will be displaying a prototype of the screen as soon as August 12 in Vancouver’s International Conference and Exhibition on Computer Graphics and Interactive Techniques, and it might just be effective enough to change the way people read. Why be dependent on a pair of glasses to make your eyes adjust instead of having a tablet that adjusts to your eyes?
Anyway, for now, it is clear that the future is the wearable technology.
P.S. Once these smart glasses are launched, mSpy mobile tracking app will be looking for ways to become compatible with them.
