Bluetooth research

• A short-range wireless technology designed to allow connection of portable devices in a wire-free manner. It offers short-range wireless communications between compatible devices for transferring data files such as photo or music files
• It is used to transfer multimedia content such as audio, video, text and animation to other devices that have Bluetooth capability. Examples of Bluetooth capable devices include phones, laptops, computers etc…
• There are different types of bluetooths. The exterior features of Bluetooths vary according to the manufacturers. These are visible differences but there are types of Bluetooth with different interior technical distinctions.
Firstly there are classified by their power levels. There are three basic power levels: Class1 devices which use 100mW (milliwatts) and have an operating range of up to 100 meters, Class2 devices which use 10mW (milliwatts) and have an operating range of up to 10 meters, and Class3 devices which use 1mW (milliwatts) and have an operating range of 0.1-10 meters.
Bluetooths are also classified according to their security levels: Mode1- Non-secure where No security is implemented, Mode2- Service-level security where Access is granted to individual services, and Mode3- Link-level security where Security is enforced at a common level for all applications at the beginning of the connection.
• The advantages and disadvantages of each type is pretty self explanatory. Obviously if you have a Class1 device with Mode3 link-level security, you are much better off than if you were to have a Class3 device with Mode1”non-secure”. But the advantages and disadvantages of Bluetooth as a whole are:
Advantages:
 Inexpensive
 Its range for transferring files even when you have walls, windows, or other physical obstructions.
 Automatic(unless you set it to manual)
 Wireless
 Bluetooth devices are capable of communicating with multiple other Bluetooth capable devices at any given time.
 Low energy consumption, which means longer sharing.
 Share voice and data
 It is upgradeable
Disadvantages:
 Minor interferences (however the new technology is rapidly fixing emerging problems like these ones in an instant)
 Bluetooth implementations normally limit the PIN number range. A PIN number is usually only four digits and the scalability for large environments is difficult.

• The YouTube video explains how Bluetooth works. But this is how it works: It comprises of a base band processor, a radio and an antenna. The base-band processor converts the data into signals, which radios can decipher. The antenna of another blue tooth device, within at least 30 feet distance, receives a transmitted signal in the air. The signals are processed in the reverse order. Bluetooth technology provides a 10-meter personal bubble that supports simultaneous transmission of both voice and data for multiple devices.
• Bluetooth was introduced by Toshiba for $199. Now it can range from $40 to $200 depending on the type of the device.

• This website states that there are going to be two new versions of Bluetooth available for the market in 2011. These include Bluetooth 3 which has 802.11 as a bearer-This bearer apparently makes data transmission faster. It is very suitable for consumer class lifestyle as consumers are demanding for a greater bandwidth in order to transfer large files such as images and videos. Bluetooth 4 will introduce a new low-energy (LE) mode that will enable communication with external peripherals and sensors. This will be used more in the industrial areas such as fitness, healthcare and environmental control. They can also use it enable new functions in handsets such as autolock when users move away from them. The improvements for Bluetooth always include better security levels and battery life.

Handheld Research

• A handheld device is a pocket-sized computing device, typically having a display screen with touch input and/or a miniature keyboard. We use it for entertainment (camera, games, music, videos), storage so that we can access multimedia while we are on the go, organization with the help of applications such as calendars, memos, tasks and timers, to socialize with social networking sites(facebook, twitter), to contact each other via calling or text messages and many more.
• As we know multimedia is a medium with a combination of different contents such as audio, video, animation, text, interactivity, and still images. Most handheld devices come with all of these contents- making it part of the multimedia world. We use cameras to produce images and videos, we use the microphones to record sounds, in laptops we can create animation through software, and in order to do all this, we interact with the device. Therefore it is a part of the multimedia world.
• Mobile computers – The whole idea of using a mobile while on the go is cool- it’s portability. Bu the disadvantages include: Insufficient bandwidth, power consumption, Transmission interferences in places like tunnels, Potential health hazards (accidents because of using mobile phone while driving, and human interference with device (getting used to the small keypads etc…
Mobile internet device (or MIDs)- It is a multimedia-capable mobile device providing wireless Internet access. It is a consumer class lifestyle device and runs a "lightweight" Operating system. It is also optimized for things like media playback and web surfing.
o Personal digital assistant/enterprise digital assistant
o Calculator
o Handheld game console
o Portable media player
o Digital still camera (DSC)
o Digital video camera (DVC or digital camcorder)
o Mobile phone
o Pager
o Personal navigation device (PND)
Smartphones:
Advantages:
With the help of electronic diaries, contact lists, and automatic reminders, they can help you be organised.
 Similar to a PDA, you can take notes, review and edit your appointments, contacts and documents, all while you're on the move.
 More applications are being added to smartphone to make it easier for the user. Examples include access to maps and directions, television transmissions with news coverage or weather reports to traffic information and scheduling alerts.
 Email and web access while you are on the go. The web access has also grown considerably faster over the years.
 Better information sharing- you can share files worth greater amount of data than previously.
 Greater functionality- taking a picture and sending it instantly

Disadvantages: http://it.medicine.dal.ca/handheld/connectivity/smartphones.htm
 requires an expensive wireless data plan
 bigger and heavier than a regular digital cell phone
 hard to use your PDA at the same time as talking on the phone



• The two main devices from which the others branch out are MIDs and UMPCs. Therefore here are the advantages ad disadvantages of each:

ADVANTAGES OF MIDS:
 Runs on a lightweight OS
 Useful for web surfing
 Are portable
 Can socialize online effectively


DISADVANTAGES OF MIDS:
 Internet and bandwidth reliant
 Security Issues- “spyware”
 Cost of the device
 Cost of the internet (excluding hotspots)


ADVANTAGES OF UMPCs:
 Powerful processor
 A big, bright display
 Support for the latest connectivity standards.
 Optimized for office use applications

DISADVANTAGES OF UMPCs:
 Costlier than MIDs
 Runs on a heavy OS- less battery time
• The price range of all handheld devices is from $20(calculator) to $1240(I pad).
• Nintendo 3DS. It uses the latest technology called “autostereoscopy”. No glasses required. It falls into the category of portable game consoles. This is a revolutionary technology that will change other things like televisions or even computers and laptops. Other video games will quickly grasp onto this “glasses free” 3D experience. Since it is new, a lot of people would be eager to get the latest technology but I am betting you that other problems will arise with this new invention and then again people will invent solutions for those problems. So we can see that inventions have invisible threads to them that attach to bring out the creation of other inventions.
• Sony is planning to release a playstation phone, which will essentially be a new smartphone capable of downloading and playing Playstation games. This will be popular because it will reduce the number of devices being bought by people and also makes various playstation games portable.
• The other will be a tablet device combining a netbook, and e-book reader, and gaming functionality. Another combination of entertainment for consumers that will be popular because of the reduction of devices.
• In order for handheld devices to work a range of components are essential.
• These include the display screen, sizes, storage capacity, hard disk drives, how to input data, type of keyboard, memory, Wi-Fi connectivity and camera. However I believe the main component is the battery that brings the whole device to life without the use of any wires. People are moving towards creating new batteries which are less heavy but ones that provide longer lasting battery life. In order to display content display screens of all sizes are available in today's market. The average would be 3 inches but sizes vary. The resolution of the display screen is important. This is because no matter how big the device is, you need to be able to see the content. Handheld devices also store multimedia and there is a limit to its capacity. However by inserting SD (secure digital) cards into the devices, we can invariably increase its capacity. An example could be my phone- I had put a 2GB SD card into it otherwise, my mobile would only be able to store about 20 photos. In order to store we have o input data somehow: through cameras, ports (usually USB ones), and through keyboards (such as the QWERTY keyboard or touch screen).To enjoy social networking on the go, devices work through wireless internet connection called Wi-Fi.

Difficulties/ Interesting Things/Solutions

• It is very hard to choose a template in wix because there are just so many of them. You would like to have a look on everything but time limit gets you.

• I just realized that I have too much information from the research. I probably will have to cut it down a liitle bit and include more pictures and videos , which reminds me that I have to even research videos on youtube about the specific topic I am doing and talk about it as well.

• I actually found making your own page was easier than choosing a template because the template is fixed to a certain theme but when you do it you can customize your website. This way we could also explore and find out many interesting features.

• I found out that Wix does not let me load bitmap images into the editing pages. in fact the bitmap images do not even come up on the screen when i try to upload them from my computer. The only files it supports are jpg. JPEG. Gif. and Png. files. I will have to convert them . These littl ethings just waste time.
• Wix has minipages in which you can put text. I became VERY VERY annoyed with the editing bit because you have to click on the "box" to edit. I click on it a thousand times but it does not let me edit. You have to literally click on it carefully 10 times to get it right. Then you should not put the cursor anywhere else otherwise you have to start the whole process again!! it is soooooo annooying!! I tried to close my window and open it again but still it was doing the same thing!
• There is also a problem with inserting tables into WIx or even this blogger posts. The format is completley mixed and messy. This means that i have to basically rewrite the whole thing again in point form.
• I kind of found a solution for the "table words mix up" but it was not effective. I used the snip tool and cut out the table part out of my word document. But when I added the table it was blurry. I figured out that putting it in a text box is better as we can see it clearluy and move it to our convenience.
• I have learnt a BIG lesson. I have to save my work after every chang ei make. My computer at my house kept shutting down every 20 minutes and i lost the changes i made for 5 times. Then I learnt to save it every 2 minutes.
• I did not put music in my website except for the future page because i thought that the music will interfere with the audio od the videos i put on the same pages. However i had no videos for the future page so i decided to keep music on that page.
• I also decided to put the topic of "future" in a completley different page as i thought that it is an important topic that drives attention to the latest technological updates and developments and the combination of the future of different topics will lead poeple to look at thje dramatic change in technology over many yaers.

Types of handheld devices

Jimdo

I have decided to test jimdo as it looked intersting. you have to sign up in order to edit blogs in this one: this i sthe home page:

Ok so the first problem with jimdo is that it says you have to go to your email fo rthe login instructions, but when you open your email there is nothing there. The beginning step itself comes with problems.

So I didnt get an email and i have tried it twice. But on the site you can see the various featrues it has if i were to get a mail. thi sis what it look slike after i log on :

Jimbo has differebt pages as well . 1 jimdo basic- which looks good but wehen compared to other ones it is less appealing 2 jimdo pro- which is a slightly better version and opens up more features than the basic package. and 3 jimdo business which is the ultimate webpage designing tool.

Jimdo allows me to put pictures in two very convenient ways- as little grids, which , when you click on will enlarge or as a very pro-looking flash gallery. It also allows me to put PDF files on the site.

I can also change the overall deisign, the background colour, the background pattern and the header image at the top. 

I finally got the password in my email but I had to wait for an astounding3 hours!!! Any way I logged on to the site and immediately looked at the long side bar located on the right hand side. It allowed me to change the layout of my webpage, the font and colour of every text on my webpage, completely make a new blog in order for me to post things about my website, add friends and create links to their pages( a good sign of collaboration), message my friends on twitter, statistics of Jimdo usage, and a help button. There was also a settings button which had a lot of other things in tit such as my blog and profile settings, email and domain management, widgets to add to the website, and many more. Just take a look:

In order to edit the already premade text boxes, we just click on them. Then it opens up a format similar to blogger when postings, for us to edit any changes.

VERSATILITY: Jimdo is versatile as it allows me to add HTML links, pictures, firstly photos. However when compared to Wix, I think Jimdo will lose in versatility as Wix also provides animations and way more photos than Jimdo.

EASE OF USE: Jimdo is extremely easy to use as it is straightforward. If you want to change something you just click on it. But I don’t like it when you have to actually use an arrow to move the title or picture. I would have liked it if we could just move it with our cursor. In the ease of use, I think Jimdo defeats Wix because it looks complicated. Both work on the same method but Jimdo seems easier to my brain. Jimdo had additional features that are interesting but you can only access them if you upgrade.

COLLABORATION: I do not need to worry about collaboration as I am doing the assignment alone but I heard that In order to make a website in Jimdo with a friend, it would be better if you worked on different pages and linked the pages back to one website. IF they do work on the same page, the information done by one person will be deleted as the other one save after them.
