Assignment: Touchless Technology - Due 02/1
Unit 23 - Human Computer Interaction




Human computer interactions, HCI, is a study that shows
us how people can interact with computers and to what extent the interactions between a
computer and a person is successful. The main aim of HCI is to be user friendly and help
everyday lives a lot easier without the need of specialised knowledge. HCI mainly impacts
people with medical conditions such as speech and sight problems by making their standard
living less difficult for them. Overall, HCI has a great impact on culture, society, economy and
future developments. I will go into details to what extent this has an impact on all four.




Society:
There are many difficulties in society that many people face in their everyday lives. HCI can
assist and aid people with their daily complications. There are a variety of human computer
interactions that are being used today that are beneficial and supportive. HCI provides some
specialised interfaces that help disabled people, these include, but are not limited to, speech
and sight problems. An example of this is an eye gaze, this is a hands-free device that allows
you to navigate your eyes to carry out tasks and communicate. This is advantageous to people
with cerebral palsy and makes their everyday lives easier. This is reinforced with other hands-
free devices such as a mouth stick which is a device that has a rubber mouth gear in one end
and a point at the end which helps them also communicate.

, In addition, HCI also helps in other ways by reducing complexity in standard living, this is
easily achieved by virtual reality.




Virtual reality is a computer-generated simulation where you use a special headset or goggles
to interact with the 3D artificial world with an option to make the simulation like your world or
completely different. VR aims to become more accessible within everyday jobs. An example
of a VR is Facebook Oculus; they are a pair of goggles that will work with your laptop that
gives you an opportunity to explore an artificial world. Virtual reality is suitable for all different
learning styles and are done remotely, this makes VR cheaper and less time consuming. Head
up displays help reduce difficulty driving, this is a device that presents relevant data such as
speed, navigation and other information without requiring the driver to look away from its
viewpoints. These head up display devices are now popular and installed in new and improved
cars.




This is reinforced with a new system by the name of fly by wire, this replaces manual flying by
converting the pilot’s movements into electronic signals. An example of this would be autopilot,
this is embedded in newer and updated airplanes. HCI on airlines are advantageous and a lot
easier to pilots as the system display vital information without the pilots needing to look which
is like heads up display in cars. This makes it even safer as the important data can assist the
pilot to make better risk-free judgements.
Many HCI improves usability for everyone, this is mainly because it reduces specialised
knowledge on how to use their gadgets (devices). These are now integrated in many people
everyday lives. An example of a human computer interfaces that reduces complexity and
specialised knowledge are touch screens, speech recognition, virtual assistants, Siri and
Alexa. One example of speech recognitions is, Satnav. This helps navigate drivers to their
desired destinations without requiring them to look at their mobile or maps. Another example
are automated calls; these are pre-recorded messages that aid the callers and its benefits
business and companies as it controls their calls leading them to requiring less call operators.
Touch screens on phones, laptop and other devices are a lot easier to use as the screen are
wider and you just need to touch the icon of the app you desire to be on. All examples that
have been presented are proven to be user friendly as it reduced complexity and their
specialised knowledge isn't needed.
