My Reflection of RES701

For this blog im writing a reflection of the RES701 paper.

The RES paper helped me learn and understand the thought processes and procedures needed to correctly identify and analyse academic papers. It has also given me some well needed knowledge on the types of areas of research and the different methods that are used with each type of research. These are all important skills that I hope to utilise next semester with the project.

What I liked the most was the critical thinking that went on when trying to answer some of the questions presented to us during the paper. I’ve always enjoyed the kind of deep thinking that comes with these types of philosophical questions and I enjoy challenging the norm.

Clare is an excellent tutor and I would be glad to sit any paper with her again. She has a relaxed teaching style so it’s easy to feel comfortable with her, this makes the classroom a nice area to be and makes it easy for people to ask questions.

Overall I think the paper was great, the research skills acquired in this paper are invaluable and an important part of understanding what will be required of us next semester for our own project proposals.

 

 

18 Quintillion!

Finally an Exciting Game

I’ve been watching a game of particular interest to me lately. It’s one of those games that breaks out of the seemingly repetitive style of gameplay of a lot of games these days. Generally when you play a game, you play along a set storyline with a set amount of maps/levels and everything sort of becomes quite predictable.

No Man’s Sky breaks out of that mould and that’s what makes this game exciting. The game is a huge multiplayer universe that revolves around space and planet exploration all on an extremely huge scale.

18 Quintillion (18,000,000,000,000,000,000) planets to explore!, that’s so many that the creators believe gamers will only ever see 0.1 percent of the total game. Each player starts in their own spot in the universe ensuring each play through  is unique to any other. When landing on a planet you can almost guarantee that no other player has been there before and because of this you have the ability to name the planet for any future players to see if they should venture upon it.

Anyway explaining it just doesn’t do it any justice so here’s a  20 minute teaser and game site for the game which is due to be released on ps4 and PC at the end of June.

 

 

Mousejack

While looking through the technewsworld site I came across an interesting yet alarming new exploit which could be used on 80% of wireless non-bluetooth keyboard and mice.

The Wireless Keyboard and Mouse

Wireless mice and keyboards use radio frequency which is sent to a radio receiver, typically a USB dongle device. When they were first created the engineers were worried about the possibility of hackers intercepting the keystrokes of the users keyboard. In order to counter this problem the engineers designed the keyboards to encrypt all keystroke data sent to the usb dongle so that if someone did hack the dongle they couldn’t use the data for malicious activity.

However, hackers have found an exploit in the software of affected dongles. This exploit allows them to send unencrypted keystrokes to the operating system as if the user had been typing them into the keyboard themselves. The device used to carry out the hack costs no more than $30 so is easily obtainable by anybody.

When you think of keystrokes, you generally think about someone typing away on a keyboard at 40-100 words per minute at best, right? Well hackers could simply create an automated program which could run up to 1000 words per minute, all from over 200 metres away.

This could cause a substantial security risk to business and personal computers everywhere. Imagine the damage that could be done accessing a network administrators computer and hacking into the businesses network or extracting confidential information from the CEO’s computer.

What? Li-Fi?

Today im going to blog about the activity we did in class and then tell you a little bit about this new technology called Li-Fi.

Class Activity

In our previous class we were asked to answer a few questions related to which area of I.T. we find the most interesting. Completing the answers to the questions should help us to figure out and decide which subject we will choose for our assignment 3 research assignment.

For me it was quite challenging trying to answer the questions given to me. I am interested in most areas of information technology so ultimately answering this question was impossible. I decided to go with something that has been quite prominent in tech news lately and that is Virtual Reality Gaming.

VR is a huge step for gaming and is allowing us to be immersed deep into our gaming world(s). The technology is still fresh and a few of the major VR headset players are yet to release their products but give them a few years and we’ll all be powering up our consoles and computers to escape into our alternate realities.

Of course such immersion may make gaming far more addictive for some and the psychologic effects of such addictions is still unknown but playing games in VR is certainly an exciting prospect.

Li-Fi

Ever had the problem of multiple people using the same Wi-Fi and slowing your throughput down to a crawl? How about a large file that you need to download and you only have Wi-Fi access so it takes forever and a day to download?

Wouldn’t it be nice to have fibre speeds wirelessly?

Well, now we do and it’s called Li-Fi. Li-Fi technology uses visible light communication (VLC), a technology created by Harold Haas, to transmit data at incredibly high speeds. In a lab environment testers were able to transmit data at speeds of up to 224 gigabits per second, yes you read right GIGABITS!.(“New Li-Fi Internet Is 100 Times Faster Than Wi-Fi”, 2015)

The way Li-Fi works is it transmits on-off signals via an LED light flashing at extremely fast speed in order to relay messages in binary code. The flashing of these lights is too fast for the human eye to perceive so will not cause a nuisance visually.

1111Image credit: Illustration showing how Li-Fi could be operated in an office setting, with data being transmitted by ambient LED lights using visible light communication. (Little, 2010)

The first test in a real world trial by the Estonian company Velmenni has produced speeds of about 1 gigabit per second which while much slower than the lab tests speeds are still double the current Wi-Fi speeds available which are in the vicinity of 600 megabits per second.(“New Li-Fi Internet Is 100 Times Faster Than Wi-Fi”, 2015)

There are other benefits to this technology as well as fast speeds:

  1. Light cannot travel through walls making local network more secure
  2. Much wider frequency range than Wi-Fi
  3. Light bulbs will become multi-functional
  4. Current LED bulbs could easily be fitted with the Li-Fi technology by fitting a small microchip inside them.(“New Li-Fi Internet Is 100 Times Faster Than Wi-Fi”, 2015)

However there is a problem with the Li-Fi technology as the moment, the signal is lost once the connected device leaves the room. Fixing this problem is crucial in order to make the technology more attractive.

There are many other areas that this technology can and will be used, if interested I encourage you to read the article by Thomas Little of Boston University here:http://www.bu.edu/smartlighting/files/2010/01/Little_ERC_Talk.pdf , the article is reasonably old (2010) but does show many other uses for VLC .

It’s going to be interesting whether this technology will replace Wi-Fi or work in combination to achieve a better overall result. One things for sure: I’ll be watching this space closely.

Reading Academic Article

For the blog this week we have to analyse one of the articles we chose last week and answer the following questions:

My chosen article

Nericell: Rich Monitoring of Road and Traffic Conditions using Mobile Smartphones.

Did the abstract tell you the three things I said it should? If not, what did it tell you?

Mostly yes, I did find the three key parts in the abstract but it only said that there were interesting results rather than explaining what they have discovered.

The abstract explained what the problem was with  and what they intended to do to remedy the problem.It also told of some of the problems they had while using the new method.

What seems to be the research question(s) they were trying to answer ?

How to efficiently use the accelerometer, microphone, GSM, and GPS sensors in mobile smartphones to detect bumps and potholes, braking, honking and determine location in an energy-efficient manner.

What method(s) did they use to answer the question(s)?

They used the quantitive research method.

How credible do you think the paper is?

I think the paper should be reasonably credible as the authors are Microsoft Researchers and they have many citations to their work ( most notably Venkata N. Padmanabhan who has nearly 27,000 citations)

This article has been cited over 800 times

Did you agree, or not, with what they wrote in their conclusion? Why?

Yes. The methods and algorithms looked to be well done and the authors ultimately achieved what they set out to accomplish.

Briefly describe two things that you learnt from the paper

The amazing amount of information that can be obtained from using the various sensors of the smartphones and applying certain algorithms to them.

The technique they used to overcome their consumption problem was very interesting.

Describe what the paper is about.

The paper focuses on the Nericell traffic monitoring system. The main objective was to develop a system with efficient power consumption, as well as overcome other smart phone sensor problems.The paper explains the various algorithms, methods, techniques that the authors used to transform the sensor information into usable data.

The authors concluded that the Nericell system with their special ‘trigger’ sensor technique would only use roughly 9.7% more battery power on a device with this running, ultimately meaning the app will have very little impact on the smartphones battery life.

Observational Research

This week we were asked to investigate and answer questions related to the topic that was randomly assigned to us.

My topic was Observational Research.

What is Observational Research?

Observational research is just that, observational. The research generally involves the researcher observing ongoing behaviour of the subject. They then record any changes as they are observed by the researcher(observer).

What kinds of questions/problems might it be used for?

This type of research is commonly used in social sciences and marketing. It is normally divided into naturalistic observation and participant observation. The naturalistic observation has no intervention by the researcher and there is no manipulation of the environment this ensures that this is behaviour that would occur in real life.

With the participant observation the researcher intervenes in the environmental variables, this allows them to observe behaviour that would not normally be accessible or available.

How could it be used in IT research?

This type of research can be used extensively in IT. Think of something such as a new application, The researcher observes the users using the application and notes the problems the user came across and the paths chosen. After the observation the researcher can then see where in the application the problems lay and adjust the application accordingly.

What are the strengths of the approach?

  • It is a very direct method of collecting data.
  • It is best for the study of human behaviour.
  • The data collected is normally very accurate and reliable.
  • It doesn’t rely on the willingness for people to provide information.

What are the weaknesses of the approach?

  • Problems of the past cannot be observationally observed nor can opinions.
  • The observational approach involves a lot of time as the researcher has to wait for the event to happen in order to study that said event, this can also make it more expensive.
  • Complete answers can’t be obtained for a problem by observational research alone.
  • It’s susceptible to the observers bias
  • It doesn’t answer the question ‘why?’

The Truth about the Truth

This weeks class was a real eye opener for me and really made me think about the meaning of the words we use and the different interpretations of those meanings.

To start off we were put into random groups of approximately 6 people. Clare then presented us with a set of questions which we set about answering during the class.

She put the questions up on the projector and I remember thinking to myself ‘awesome we’ll fly through these 10 questions easily’, little did I know the questions would be a lot more difficult to answer than I had previously thought.

We spent quite a while discussing and debating within our group the answers we thought were fitting to the questions that were asked. Some questions, in fact, most questions we could not answer with 100 percent confidence that they were correct.

What before seemed like simple, straight forward questions were now complicated, mind bogglingly deep and complex. Just when I thought I had the answer to a question I found myself asking more and more questions and never really arriving at a definitive answer.

All of this discombobulation was centred around and ultimately came back to one question in particular ‘what is truth?’. Before you answer think about the real meaning of the word ‘true’. Here’s a couple of common definitions of the word true: ‘that which is in accordance with fact or reality’, ‘accurate or exact’.

Now think about this hyperthetical scenario: A Jamaican man and an Eskimo are sitting in a room in New Zealand in mid-summer. The Jamaican says “brrr, it’s freezing cold in here” but the Eskimo turns to the Jamaican and says “No, it’s roasting hot!!!”. Both of these men think they are telling the ‘truth’ and they may well be in their eyes. The Jamaican is shivering but the Eskimo is sweating so who is telling the ‘truth?’ which is the fact or reality?, Which is accurate or exact? can they both be telling the truth even though it seems silly that it could be hot and cold at the same time?.

This brings me to an interesting thing about ‘truth’: In English the word is used objectively and subjectively. Objective truth means that something is true undeniably, it is an unbiased fact which feelings, thoughts, beliefs or ideas have no bearing e.g. humans must breathe air to survive.

Subjective truth means that it is ‘true’, or is believed to be true, for the person making the judgement but not necassarily true to others, this is where my previous example about the Jamaican and the Eskimo comes into play. Both men believe themselves to be telling the truth. I think the word ‘believe’ is key here, once emotions come into play we are no longer talking about the real ‘truth’ but a thought, a belief, an opinion that it is true, all of which can have an opposite thought, belief or opinion.

Just a little bit of food for thought…….

Once the class was over Clare asked us to answer a few questions in our blog

What is ontology? How is it relevant to research?

  • Ontology is the philosophical study of the nature of being, becoming, existence or reality.
  • It tries to pin point things around us that actually exist
  • It’s relavent to research because it’s about what things are and describing these things and their relationships.

What is epistemology? How is it relevant to research?

  • A branch of philosophy about the study of the nature and scope of knowledge
  • It aims to discover the true meaning of knowledge
  • Its relavent to research because its about researching knowledge asking questions like how? and why?.

What is the connection between ontology and epistemology in a research context?

Theres a connection between these two philosophies and together by asking what is this? and then asking how and why is it we think this is this?, this allows us to research more thoroughly and see things from multiple different angles and also helps to keep research unbiased.

 

 

 

 

 

 

My first Res701 blog

2/3/2016

Welcome to my first blog for my Res701 paper

For the first class of the paper our tutor Clare showed us through the course outline and described what we should expect to achieve from this course. We had a look through the different elements of the assignments of the course and course outline.

Clare explained to us that the paper was originally about research methods but is now more of a preperation paper for our project paper.

We were tasked with setting up a blog each which we will be expected to complete regularly during the semester. My blog will be a type of journal that will hopefully provide me with some good material to look back on and help with my project paper next semester.

Once our blogs were set up and linked to the Res701 class blog Clare set up a Powerpoint presentation. The presentation was a good little introduction which helped us understand what research is and how it is used.

After the presentation we were asked to answer some questions on our blog:

What do you think research is?

Research, in my opinion, is gathering knowledge on something and using it in a particular way which discovers something new or adds to the knowledge of that particular thing.

Do you think you will ever need research skills?

Absolutely, I believe research skills are essential to making good decisions in all areas of life. I commonly use research skills to ensure im getting the best product and best price for that product but I also use them to identify good places to travel, things to do and of course use them in my study for my degree.

This course will be excellent in helping to better improve my research skills and aid me with my project paper next semester.

What do you think a research journal is and who is it written for?

I think a research journal is a way to collect and record ideas, thoughts, methods and findings on an area or areas of research. It can be used by the researcher to review their own research and reflect on it and can also be used by others for their own research or for them to peer review the research and make recommendations to the owner.

What is plagiarism?

Plagiarism is when someone takes or copies another persons intellectual property such as ideas, thoughts, research etc.  without acknowledging the original author/creator of the property, essentially attempting to pass the stolen work off as their own.

Why is it important to avoid it?

It is important to avoid plagiarism because intellectual property is owned in the same way that physical property is owned. Copying or taking somebody’s intellectual property without permission is illegal and is theft which can lead to prosecution.

It is also morally wrong to steal someones intellectual property, everybody should be intitled to create their own ideas and share knowledge without the fear of having it stolen or copied.
