Impact of HCI on Economy

The Impact of HCI on Economy
The development of HCI’s has increased the productivity of technology and the users of technology by reducing the necessary input and therefore speeding up input. This makes the technology easier to use, and also allows the technology to do more in a smaller amount of time, with less resources and at a lower cost, increasing efficiency. These developments will allow technology to perform more tasks that it cannot currently handle, and allow the user to do less as the complexity of user input is reduced. Technologies like this can increase the workload of a person in a business, and allow more people with less specialised skills to be able to perform the job.
Human input can be reduced with technology such as text-to-speech software, which will allow documents to be read aloud by a synthesised voice. This can be applied in education, where a written document or a book extract for example, can be read out loud by a computer whilst the lecturer is able to do other work. This increases productivity, and reduces the margin for human error which increases the standard of education, ensuring good reputation for the place of education.

For industrial purposes, automatic judgement of output will ensure accurate results of manufacturing; reduce the amount of time it takes to manufacture products and save money on production as fewer employees are required. Although this saves the business money, there will be less available jobs, and as less skilled people are required, it would be harder for someone with good skills to get the same job. As the business would save money, this could mean that staff can be kept and retrained for other jobs.
A more recent development that has strong potential for applications is speech to text software which allows voice input. This is useful in education where a lecturer can teach a lesson whilst anything they say is recorded. This enables students who are not in the lesson to get an idea of the lesson content. It can also be used to allow deaf people to understand what is being said to them. This enables further communication and helps people with hearing impairments to communicate better in a place of work. It can also be used for accurate note taking, and will ensure that all staff or students, depending on its application, have all the notes from the lecture or speech, and can use it to ensure that the work they do based on these are more accurate, and allow for better results. In a business, this means that there is a reduction in human error, and the business can be more profitable due to less waste, better products, and better customer satisfaction.
Thought input, can be used to allow a person who cannot speak, write or type to perform tasks that require use of hands or voice. It enables people with disabilities that affect speech and movement to communicate and allow them to be more independent. In future uses, it could be good for design, allowing designing to make digital representations of their thoughts and create products according to these thoughts. This could make jobs easier as it requires less effort and ensures a wide variety of people can perform normal jobs with ease, making it easier for people with disabilities to earn a living.
Mobile communication has a large impact on the productivity and efficiency of people and computers. The impact can be both positive and negative depending on how mobile communication is used. It can be positive as it enables communication between people where it may otherwise be difficult, and ensure that staff in a business know what they need to do for example, it can also allow remote computing or remote access to files that an employee may need which would save time and increase the productivity of the staff members, but also it would save money as the staff would be able to work faster and more efficiently. It can be negative as some people may be distracted my things such as social networking which would reduce productivity and have a negative impact on a business.
HCI’s are recently becoming more intuitive, determining the steps a user will take and doing them in advance. By remembering individual user’s preferences and actions, tasks can be simplified for the user. They can be used to detect certain aspects of a user, eliminating the need for human input. This could be the room the user is in or the mood the user is in for example. This allows the actions to be automated, although this could increase the chance of inaccurate results. By detecting staff who enter a room, a computer system could prepare an environment for them, such as by logging them into a computer, preparing tools or even producing food to the user’s taste. This can make jobs easier and help the staff be more productive if menial tasks are reduced or made easier.
HCI is also having a negative impact on the economy, as computer motherboards are being taken to poor areas of countries such as India, where the components are stripped off the motherboard and reused. This is done because the labour is cheap, but there is a lack of concern for safety, as the workers are not supplied with safety equipment such as masks, gloves or even appropriate tools to salvage components safely. The workers are at risk of poisoning from hazardous chemicals and gases and other substances such as lead and mercury. They are also at risk from infection and harm from sharp components. Electrocution is also a risk especially from components such as capacitors where the electrical charge can be stored for days. It does, however, provide a job for the people who do this, as the constant production of computers provides a constant supply of motherboards for the staff.



  1. This document fulfils the requirements of the user on the society, culture and the economy. The text is easily visible to read for the visual impaired. The text is easily to read with the black background. The text is white which stands out well. The background is black and there is a picture behind it. It is suitable for the blog as it is simple and easy to see. The colours would work for colour blind people and visually impaired people as it is in black and white and it stands out well. The images used are suitable for visually impaired people as they are large enough to see. The features of the blog as very nicely laid out and the fish features are also well placed. The things that you could improve for the blog would be to make the text size a bit bigger so that visually impaired people can read it. The text font and the background work well for this blog. It is easy to navigate through this blog as you can use the archive to get to each of the pages. It is simple to comment on this blog as there is a box at the bottom of the page so that anybody can comment on this page. The blog is suitable for a wider audience because people can share this on other websites like facebook to get other people to read it.

  2. How well does it fulfil the requirements of describing the impact of HCI on society, culture and the economy?
    This does fulfil the requirements set by our teacher.

    Is the text size sufficiently large to be read easily by the visually impaired and how does it stand out against the background?
    Needs bigger for the visually impaired but it stands out form the background.

    What colour is the text and how does it work with the background colour?
    The text is in white, the hyperlinks are in red and a black background

    Describe the background – is it an image or plain colour?
    It is black.

    Is it suitable for the web page/blog?
    It is sensible for the work we are doing at the current time, it set with the theme very well.

    Comment on whether the colours work for colour blind users and also for the visually impaired.
    Since white is a rare colour blindness it does stand out for the visually impaired and colour blindness is not affective.

    Describe the images used.
    The images used in this web page show a on window screen speedometer and a joystick.

    Are they appropriate, well laid out on the page?
    They are in the same area as what they are talking about, for example there is window screen speedometer in the area where it says about helping our daily lives.

    Are they large enough for visually impaired users?
    They are large enough so they can be read but they are small enough to stay on one page as a web picture.

    Comment on what works well for the blog and what doesn’t work or that could be improved on the blog/web page.
    There is nothing that needs changing.

    Is it easy to navigate and how is this done?
    It’s all on one page it is easy to navigate.

    Overall is the web page suitable for a wider audience?
    Yes it is suitable for any type of audience.

  3. In this blog you have describe the differences in the associations about the economy. This is very clear and precise, the wording is large enough to be read by a visually impaired person. you have explained clearly in your own words how these things have affected the world. The color you have chosen is very appropriate to the topic. Overall this presentation is very exceptional.
