Mobile ComputingInformation on the go!

So many mobiles…

Mobile device, mobile computing, mobile hardware, mobile software, mobile communication, mobile app, mobile network, mobile internet…

How do we make sense of all these words?? Let’s start with one Mobile Computing

Page 3: Artist l1mobilecomputing

Mobile ComputingA type of Human Computer Interaction (HCI)

“Taking a computer and all necessary files and software out into the field.” (Wiki)

The idea is that we can have all the power of a computer into a device that is easier to transport and take “on the go”

Page 4: Artist l1mobilecomputing

3 Main Categories of Mobile Computing

1. Mobile HardwareDevices, pieces, accessories

2. Mobile SoftwareApps, bundles, coding

3. Mobile Communication

Cellular networks and services

Page 5: Artist l1mobilecomputing

1. Mobile Hardware

Includes (but not limited to):

PDA’sPalm Pilot, other versions by Palm, first in 1984

Page 6: Artist l1mobilecomputing

Mobile Hardware (cont)

SmartphoneA “miniature computer” that can also place and receive phone callsiPhone, Android, Blackberry, Windows Mobile, etcFirst smartphone by IBM in 1992 called “Simon”

(http://cellphones.about.com/od/coveringthebasics/qt/cellphonesvssmartphones.htm)

Page 7: Artist l1mobilecomputing

Simon?The first Smartphone created by IBM in 1992

• Simon had features such as touchscreen, email, and PDA , which was extremely advanced for its time

Yours for only $899 (at the time)!

Page 8: Artist l1mobilecomputing

Mobile Hardware (cont)

Tablet computerA larger version of a SmartphoneMoveable, more flexible use compared to a computer (no mouse, keyboards, etc)iPad, Blackberry Playbook, Kindle, HP, Samsung, Acer, and many more have their versions of the tablet

Page 9: Artist l1mobilecomputing

Mobile Hardware (cont)

Ultra mobile PCA class of laptops launched by Microsoft and Intel in 2006

A mixture between Smartphone & tablet

Sometimes include keyboards and webcams

Page 10: Artist l1mobilecomputing

Mobile Hardware (cont)

Wearable computerAka “Body borne computers”Constantly in contact with the user, no on/off switchInteracts with the human bodyCommon example is a running watchThey are UP AND COMING!!!!!

Page 11: Artist l1mobilecomputing

NY Times cited: “Wearable devices, or ‘wearables’ for short, have enormous potential for uses in health and fitness, navigation, social networking, commerce, and media,” (Bilton 2012)

Page 12: Artist l1mobilecomputing

This is our future?!

Page 13: Artist l1mobilecomputing

Evolution of Mobile Hardware

Getting smaller

Cheaper- cost production has greatly decreased

Faster- increased battery life, longer talk & standby

Lighter- they weigh less

More efficient, more capabilities & features

How does a Smartphone work?

Inside the phone is a speaker, microphone, keyboard, display screen, and a very powerful circuit board

They all act together to make the phone work

Signals are passed back and forth from the device to the nearest base station (tower)

Communicate via radio waves…but this is subject to change!

Page 16: Artist l1mobilecomputing

A look inside

A cell phone is much like an onion, it has many layers that sit atop each other, helping to carry out tasks on the phone

Page 17: Artist l1mobilecomputing

Circuit Board•Phones are generally powered by battery.

•Electric signals are transmitted through wires and boards to create a transmission cascade within the phone, which is then displayed on the screen

Page 18: Artist l1mobilecomputing

2. Mobile Software

Operating Systems (Mobile OS)

Much like the operating systems for computers

PalmOs, Nokia Mameo, Android from Google, iOS, web OS, Bada OS from Samsung, Blackberry OS from RIM, Windows for Mobile devices from MicrosoftCombines features such as touchscreen, wireless network, Blutooth, GPS, camera, voice recognition, etc

Page 19: Artist l1mobilecomputing

Mobile Software (cont)

Apps

Are a software application designed to run on a mobile device

Apps are BUNDLES

Originally, designed for general productivity

Info retrieval, email, calendar, contacts

Easy access to large amounts of info

More recently , designed for entertainment

Games, banking, GPS services, purchases

Page 20: Artist l1mobilecomputing

Mobile Software (cont)

Apps (cont)Application Distribution- apps come a variety of platforms such as “app store” and “app world”

Some apps are pre-loaded on the device and “locked”

Others are bought or downloaded for free

Page 21: Artist l1mobilecomputing

How apps work?Apps are bundles of code that work much like programs on a computer

They must be downloaded, installed, and opened to operated

A lot of hard work and code goes into the making of an app!

Page 22: Artist l1mobilecomputing

Apps that are really useful

Page 23: Artist l1mobilecomputing

Apps for fun

Page 24: Artist l1mobilecomputing

3. Mobile Communication

The idea that our mobile devices can act as communication devices

Works by sending & receiving radio waves through a chip built into the device

SIM Card- microchip “Subscriber Identity Model” that stores information

Slowly moving away from these

Page 25: Artist l1mobilecomputing

Mobile Communication (cont)

Phone Calls- much like radio waves, two or more people communicate on a “channel”

SMS & MMS MessagingShort message service (a text), multimedia messaging service (picture/video message)

Internet accessAbility to connect to WiFi, 3G, 4G, LTE networks

Short-range wireless sharing (Blutooth, Infared)

Page 26: Artist l1mobilecomputing

Benefits of Mobile Devices

Information on the go, at our fingertips

Generally user-friendly

Lower cost compared to PCs

Less energy to run

Connects people across the world

Entertainment

Safety- they can carry medical emergency information

Can help with special accessibility needsVoiceover, speech recognition

Page 27: Artist l1mobilecomputing

Major benefitMobile devices in the workplace

Can connect workers & help them to communicate

Can be used as reference or tools to collect info

Mobile devices in the health field as hospitals begin to go paperless

Reference guide for physicians and nurses

Ultrasound mobile attachment

Page 28: Artist l1mobilecomputing

How mobile devices can ease everyday tasks

iPhone credit card slider

Monopoly “snapped” edition played with the iPad

WiFi Body scale that sends info to your mobile device

Page 29: Artist l1mobilecomputing

More cool gadgets

iBaby Mobile Baby Monitor

A chip on your pet’s collar to track where they are at all times

Page 30: Artist l1mobilecomputing

DisadvantagesProduces “non-thinkers”, reduces our creativity and ability to think on our own

Harder to protect intellectual property

Less privacy- your information is being tracked every second

Page 31: Artist l1mobilecomputing

Disadvantages (cont)

Negative health affects

Links to cancer? Exposure to radio waves

They can be distracting

Texting and driving

Older generation might have a hard time using

Page 32: Artist l1mobilecomputing

SummaryMobile computing can be performed on multiple types of devices

These devices are much more portable and thus increase our capacity to find information

However, our dependence on them is becoming apparent and they can sometimes be distracting

Mobile devices are moving towards more “wearable” devices in the future
