As a requirement for this paper, we must set up and update a regular blog with information learnt from the course. A blog is a website, where people can set up their own personal page and update it with any information they want to share. It can be written like a diary, a journal, a travel log, a political voice, anything the author wants. It is interactive, with others able to view and comment on it and the information can be linked to a variety of other internet sites. It is fully controlled by the author, who can set it up with their own personal preferences, control who views it and edit any comments that others put on it. It can also be used to link people with common interests, as well as sharing photos and website links that they may think others will find interesting. Blogger.com is one of the main websites offering a simple way to get into this, however there are others such as twitter and facebook, which allow basic blogs, through to specialist blog sites in different subject matters.

So, blogging is a great way of sharing information and gives us as students a chance to record our learning during this course and share it with others.

Tutorial Two: Digital cameras
We are now moving on to look at digital cameras and their uses:
As technology develops, it replaces old versions which are often lost forever. However there can be some features of the old technology that the new ones just cannot replace. “A new technology is rarely superior to an old one in every feature.” This statement can be particularly seen in the development of digital cameras. The use of digital cameras and the technology within them is growing rapidly. Now days it is rare to see a film camera in use. Although digital cameras have the plus side of producing an instant image, which can be edited or deleted and is able to be stored on a computer rather than bulky photo albums, there is also a down side to them. As the image is instant, the element of surprise of what the photos will turn out like is gone. The nostalgia (or horror) that comes from looking through photos developed weeks after a holiday is not there, as the photos are able to be viewed straight away and deleted if they are bad! Digital cameras also require more equipment in order to use them. Although they are much smaller in size, they do require at minimum, memory cards to store the photos on. In order to edit and store large amounts of photos, a computer is required, which can be costly, especially if editing software is required. In order to do this, cords are also required to connect the two.
Digital Images:
As well as digital cameras, images can be stored, transferred and manipulated in a variety of other means such as mobile phones, CCTV cameras and digital video recorders. With the prevalence in society of devices that capture images, ethic issues need to be considered when using them. These can include the issue of informed consent by the person who is in the images and the ability to take photos without people knowing. Cameras can be lost or stolen, with images falling into the wrong hands. Photos can also be edited very easily, manipulated to different purposes other than the original. Digital images are frequently being used in OT practice, as ways of assessing and analysing occupational performance, as well as incorporating them into treatment plans and evaluations.

Digital and optical zoom: Digital zoom is when the image is cropped and the enlarged by the computer, which reduces the picture quality. Optical zoom is when the image is magnified by the lens itself and produces a better quality image. (Retrieved from http://www.frogprints.co.nz/help/focal.cfm)
Megapixel: Digital images are made up of millions of small tile like elements which are called pixels. A million pixels are called a mega pixel. The more megapixels in an image means that it is clearer, with better definition. (Retrieved from http://www.digicamhelp.com/camera-features/camera-parts/megapixels/)

Tutorial One: Information technology and ethics
Here goes the first blog attempt!
As a requirement for the Otago Polytechnic Bachelor of Occupational Therapy course, we are looking at information technology and its place in today’s society. Information technology is the production, storage and communication of information using computers and micro electrics. Over the past 20 years it has become increasingly commonplace in our society, affecting almost everything we do. Computers and electronic equipment are seen in the majority of households and business in
Some IT devices or systems that are fairly commonplace in everyday life to produce and communicate information are: telephones, mobile phones, satellites, MP3 players, DVD players/ recorders, books, computer programmes (word, PowerPoint etc), internet applications (e-mail, social network sites, search engines etc).IT is used frequently within occupational therapy practice, for both practitioners and clients. From computers and internet which both provide information (Websites, e-mails) as well as a way of storing and sharing it; through to assistive technology to aid clients to complete meaningful occupations for them, the role of IT is growing within the profession.
Many ethical issues arise from the use of technology, especially as it rapidly grows and more information is available for everyone to see. Some useful terms to know are:
Ethics: these are moral principles that guide the way we act and behave and therefore computer ethics are principles that guide the use of computers. (Retrieved from http://www.techterms.com/definition/computerethics).
Privacy: The idea of privacy can be seen as the restriction of access to materials, however the definition is rapidly changing in terms of information technology as the boundaries become blurred between public and private information. (Bynum & Rogerson, 2004)
Intellectual property: or who owns what on the internet. Those who create or own information can make a lot of money from copyrights, however as the information can so easily be changed on the internet, policing this becomes difficult. (Bynum & Rogerson, 2004).
Informed consent: This is when a person has given consent for something when they have a clear understanding of what it is and the implications of that action. (Retrieved from http://en.wikipedia.org/wiki/Informed_consent). This can be a huge issue with technology, especially with the growth of digital images and the ability to edit items.
Social Justice: The access to information for everyone can also mean that those who are unable to access technology may miss out on advantages that are available to those who can. This means that society must develop practices and adaptive technologies in order to allow access to those such as the elderly, people with disabilities and those on limited incomes. (Bynum & Rogerson, 2004).
