In Korea, a state-funded research institute has developed a specially-designed pen that can help solve one downside to touch-screen technology. That is, the lack of any physical sensation like the reassuring feeling that comes from pushing a button, or turning a dial. With the new invention, touch and control become that much easier. Our Yoo Jihae tells us more. Touch-sensitive screens are everywhere from car navigation systems and mobile phones to PDAs and MP3 players thanks to the rapid development of touch-screen technology. But many touch-screen users especially those who use pointing devices to make selections often find it hard to click on a flat touch screen as there is no tactile feedback to indicate the right button has been pressed. Park Hanna, PDA user: "There are times when the machine doesn't detect the touch at once. I have to check if I've pushed the right button every time, so it gets quite burdensome when I am in a rush." But it seems users won't have to stress any more thanks to a recent invention named "Ubi-pen," a device developed by the Electronics and Telecommunications Research Institute, a nonprofit research organization backed by the Korean government. Park Junseok, Head of Research Team of Electronics & Telecom. Research Institute: "We implemented a pressure-sensitive motor in a pen to generate vibrations that can stimulate a wide range of tactile sensations." People can draw along the lines and select the object with ease for if the user goes astray, they will immediately feel vibrations on the tips of their fingers that provide a sense of direction. The institute said Ubi-pens could lead to new ways of developing interfaces and also make modern computing systems more accessible to those with visual or motor impairments. Although the pens are not on the market yet, developers also said they will continue improving the design on this product that could help Korea take the lead in computing technology.
