Information systems and Human Computer Interaction became a part of the western way of life in the 1980s and 1990s. It was the age where devices like private eye, xybernaut (this wearable system was among the first commercial solutions of the 1990s) and more, were created through research and development. The most wearables systems that we know today exist thanks to these devices.The wearable research community is getting better because of the knowledge we got from the previous years and the continuously research.
Some years ago they used to use devices like private eye, xybernaut e.t.c., but nowadays given the fact that technology has been improved, we use devices like hand-held touchscreen computers that have been
widely used in wearable computing research, mobile sensing platform and more. On the other hand, future trends about HCI evolution is unknown but it is clear that it is going to get more advanced. The key issue is the
connectivity between the main computing unit and other devices, sensors in particular. In the future, the HCI is probably going to deal with 4 basic layers:1.Mobile phones, 2. Carry-on peripherals, 3. Microsensors and 4. Sensing, communication, and power generation infrastructure.
