Example of a Blog's Use in An Organization Context


The official weblog of ORBIS International, a nonprofit global development organization
http://blog.orbis.org/

It is a real example of a blog's use in an organizaton context.

The potential advantages for the oraganizaton to use a blog are:

First, ORBIS is an organization that works with local partners around the world to establish comprehensive, affordable and sustainable eye care in developing countries and eliminate avoidable blindness.

No matter how rural, remote and scattered these areas are around the world, the local partners residing in those areas can access the blog page and post videos, photographs and first-person accounts of what they had experienced for the various projects and events happening globally. Information are posted instantly from the developing countires to let blog viewers know the most updated information, and what's happening most recently.

Orbis has branches from Canada, UK, Hong Kong to Shanghai. Workers in different branches around the world can post simultaneously with the local partners working at different developing countries, which are China, Africa, Vietnam, India, Bangladesh and Latin America.

This advantage becomes even more prominent when you think of how far apart the branch offices and the local partners' offices in the developing countries are, yet workers can still exchange information together easily and help people improve their eye sights.

Other types of social media such as facebook, myspace and youtube are listed on the blog site to direct people to those sites and also drives traffic from them. This can generate awareness of the organization's beliefs, values and future plans.

The potential disadvantages for the oraganizaton to use a blog are:

Workers cannot write personal or private things other than personal accounts and feelings relating to projects and events of Orbis.

Everything shared on the blog site is visible to the public, including other rival organizations, thus gives them a competitive advantage. Everyone knows what's going on in the organization.

Blogs are easy to start but hard to maintain. Writing coherently is a difficult and time-consuming task. If the blog is not updated, it damages rather than enhances the reputation of the organization.

More over, blog sites can be hacked by the anonymous or infected with virus, so caution about the protection from virus and hackers needs to be taken all the time.

Disadvantages of Wearable Computers

The technology of wearable computers might turn us into super beings or evil cyborgs.
The potential disadvantages for organizations to use wearable computers are:
  • The development of this technology is still in its initial phase, although wearable computers had been increasingly adapted to functionality for consumers.

  • Many designs are based on the context of use rather than responding to the human computer interface and as such are not attractive characteristics for the user.

  • There are various problems relating to networking challenges, energy requirements, supply and flexibility with the system

  • Battery life is a key issue for some devices, limiting usage time before requiring replacement or recharge

  • There are health risks regarding the usage of this technology. Due to the heavy weight of the larger devices, they negatively affects the shoulders, neck and back.

  • People are afraid the technology will turn them into cyborgs and make them lose their privacy and humanity. We cannot simply solve it by making it fashionable.

The potential advantages for organizations to use wearable computers are:
  • Wearable computers are becoming more simpler, smaller and less cumbersome.
  • User's needs are satisfied and not hindered by the device
  • Constant attention and interaction are not required

  • It is unobtrusive and unrestrictive to the user
  • Users can be invloved with another activity simultaneously such as jogging, walking, catching a bus, talking to a person face to face whilst using the wearable device.

  • They provide significant contribution to maintaining health and well being. E.g. Monitoring devices are embedded in "smart" clothing, measuring heart rate, blood pressure, body temperatur...etc; Prosthetics offer enchancement of users' physical movements.

  • Commercial users will be attracted to wearable computers' hands-free operation and their ability to instantly update any information stored in the database.

  • The marines are using this technology to repair equipment on the battlefield

  • Instead of carring bulky service manuals, mechanics can use the wearables to view a transparent image of a vehicle's broken part, analyze how to repair it, update its serive records and still have both hands free to fix the broken part.

  • Some art museums in Netherlands are using wearable computers developed by MIT Media lab to deliver audiovisual narration adapting to the user's interest based on the path in the museum and the length of stops

  • Architects are using them to develop see-through buidling plans that reveal the exact locations of electricial wires, pipes, and framing hidden behind walls. If a pipe is rerouted, the plans could be instantly updated for the next repair person.

How Wearable Computers Replace Other Techology

Early wearable computers are heavy and inconvenient to wear.

Wearable computers replace laptops, PDAs and possibly desktop computers and has the potential to replace or be combined with smartphones like iphones, blackberries.

1991-1994 wearable computers are cumbersome for general use, they have a clunky handband monitor.

Now wearable computers consist of more speed and memory, they also weigh less and power consumption is greatly reduced so that fewer batteries are needed. They are also more fashionable with wraparound sunglasses that includes a VGA display for better resolution.

Unlike smartphones and PDAs, they are able to interact with the environment continuously, obtain and store specific data and recognize data (voice, letters, image) and in turn gives the user useful information. E.g. "Netvigator" an early wearable computer that recognizes voice of the name of the destination and guides user to it, developed by Professor Dan Siewiorek of Carnegie Mellon University in 1991.

Chosen New Information Technology, Wearable Computers

This picture shows the "SixSense" worn by the developer at MIT. http://www.pranavmistry.com/projects/sixthsense/
My chosen new information technology is wearable computers.
A wearable computer is a computer that can be worn on the body. These devices are very useful for users that require computational support while their hands, eyes, voice, arms or attention are actively engaged withthe physical environment.
Unlike laptops, iphones, blackberries and PDAs, wearable computers are constantly turned on and interacts with a real world task. The device is very context sensitive.

A wearable computer consists of a computing unit carried on a belt, in a jacket, on the head, on an eye piece or around the neck and arm. The display would be integrated with the computing unit or in the form of a projector attached to the computing unit like the "SixSense", which is a new wearable computing device developed from the lab of MIT. It offers profound interaction between the real world and the world of data.
