Delhi Delhi. With their brilliant touchscreens, high-resolution cameras, and sophisticated software functionalities, today's smartphones are technological marvels. They have gone far beyond their original function of just making phone calls and have become our browsing devices, gaming tools, cameras and even sources of entertainment. Can you imagine telling someone about a modern smartphone in 1999? It will seem as if you are describing a science fiction movie.
However, what will happen after that? What extraordinary characters will the smartphones of the future have? Here we consider five revolutionary ideas that could reimagine these gadgets.
1. Phones that are controlled by your brain
In the early years of mobile telephone technology, there were physical keyboards as the main interface. These were eventually relegated to touch screens and now voice assistants like Siri and Google Assistant enable us to interact with our devices using verbal instructions. Next step? Mind control.
Thinking about opening an application, changing an image or text. This goes beyond touch or voice input, where every aspect of the phone can be controlled instantly. For example, instead of clumsily trying to open an app, you'll simply focus your thoughts on it and it'll happen instantly.
Progress is being made in this area, although it may seem unrealistic. MIT has created a device called AlterEgo that enables users to communicate with machines using their thoughts. Similarly, researchers at the University of California recently used a brain-computer interface (BCI) to translate a woman's thoughts into spoken words via an avatar. Although still in its early stages, these developments mean that brain-controlled smartphones may soon become real.
2. Over-the-air charging
Modern mobile devices are all limited by battery life. Even models like the Galaxy S24 Ultra will need to be recharged after just two days of use. But in the future with the development of over-the-air charging technology these charging problems on smartphones will be solved forever, so they will always be fully charged.
Imagine a world where these transmitters are as common as cell towers, always ensuring that your device never runs out of battery power, no matter where you are. This technology will eliminate the need for cables and charging pads, but it can also be used to power other gadgets like headphones, smartwatches, etc. For example, companies like Wi-Charge are already working on implementing similar ideas by using infrared radiation to wirelessly charge devices within about 30 feet. Although current applications may be limited in scope, this technology has great potential for a wireless future.
