BP5 "Google Docs" Web 2.0 Tool
Name: Google Docs
http://www.google.com/google-d-s/tour1.html
How I would use this: This week we were to choose a Web 2.0 application that we would use for our action research project. The Web 2.0 application I chose is Google Docs. The most important feature of Google Docs that I want to use is “the forms” feature. I plan to use this for surveying information of current knowledge and current practice of the participants in my study. My plan is to target areas of information in small segments. One week web pages and another week file formats. After that a follow-up survey would be conducted to indicate how well tutoring did to improve the concepts.
Cost & Interface: Google Docs is FREE. There is a “Premier” edition that is available for a yearly fee of $50.00 per user. (The premier account has more features, storage, etc…) The Google Docs interface is very easy and user friendly. The initial navigation can be confusing but improves immediately when using the applications. Each document type has better than basic features to create very good documents worthy of publishing directly from the site. If you wish finer control of the finished product you can download your documents to your computer and edit with a computer application of your choice.
Why I chose it: The forms portion for surveys. Being able to send forms or share documents via email accounts. Google Docs has a great interface and flexible access from anywhere..
Outstanding Features: Forms, interface, access, and email connections.

W1 Reading
Modernism and the esthtics of personal computingKirkpatrick (2003) argues the question of modernist esthetics is when the computer user is at a computer; the interface offers something the individual can interact with rather than the computer representing the true machine that it is underneath the interface. Graphic interface is natural pluralism everybody can be successful. There is a conjecture of machine entering where it is all great experience with out betraying it's technical underpinnings. IT has been refined enough that using a computer no longer is represented as technology but as an enjoyable experience without betraying it's underlying technology. Computational styles emerged in the 80's that divided between expert knowledge (Hackers) and knowledgeable hobbyists. Both knew the machines inside and out but developed their expertise to different degrees. Up to 1990's it was a subculture that used "command line" interaction. The User friendly interface changing that. The question that modernist esthetics poses is that the computer user as they get more knowledgable should be able to be exposed to the inner working more and should be able to see the true machine
Hidden costs of graphical user interfaces: Failure to make the transition from menus and icon toolbars to keyboard shortcuts
Lane, Napier, Peres, & Sándor (2005) did several studies to determine efficient use of computer interfaces. Mouse, icons, keyboard shortcuts, or variations of the previous. They did two studies using more than 250 people located in various industries. The studies relied heavily on questionnaires and came up with surprising results when comparing experienced and inexperienced users. The studied showed keyboard shortcuts were used the least. The cut, copy, paste were the most used shortcuts but icon use still out numbered the keyboard shortcut. Neither experience or advanced typing skills seemed to be a factor that improved efficient use of keyboard. Possible ways for improvement was training programs with specific mapped out guidelines. Graphic interfaces are easy to learn and the visibility of the graphic interface makes them easy to use so foregoing the need to memorize commands.
Pictorial communication of abstract verbs in relation to human-computer interaction
Rogers & Oborne (1987) looked at how people would draw pictures to represent verbs like say for functions of keys or an action with a computer. There were two levels of verbs: high imagery and low imagery verbs. The recent trends are to use icons to represent actions on computers or with machinery. It has been found that icons can convey meaning quicker and more succinctly than words. The transition of this to computers is incomplete due to the uncertainty of what image conveys what complicated feature. Abstract connections of pictures versus words is unknown for variety of factors. The research has not pointed out if it makes a difference in speed or not due to high imagery words are much easier to draw for and understand.
Complexity of user interfaces: Can it be reduced by a mode key?
Musseler, Meinecke, & Dobler (1996) investigates if mode keys, which changes the function of other control elements, is a benefit to speed and accuracy in operating a device. They experimented with 3 set-ups of keys. 1 mode key and 5 buttons; 5 mode keys and 5 buttons; and 5 mode keys and 20 buttons. There are impacts with friendly or unfriendly interfaces that can positively or negatively impact usage. Mode keys for advance users is a benefit in speed especially when practiced, but there can be slowness and often wrong use with misunderstood mode keys. Design of single mode key is least efficient and in a critical speed dependent situation is not a recommended interface. The single key set-up consistently out-performed the other set-ups, but is not to say it is most efficient. Manufacturing and task affect these. Categorical grouping is helpful in efficient usage of the buttons. Study looks at how the relationship of variety/number of modes influences accuracy of usage in practiced user and inexperienced users.

BP4 "gliffy" Web 2.0 Tool
Name: Gliffy
Link: http://www.gliffy.com/gliffy/#templateId=blank&signup=1
How I would use this: This is a diagram maker to a mind mapping program. Any class where any diagrams are used or needed can use this program. Venn diagrams are used in most classes and the set of tools are great. If you need a graphic organizer this program can create one very.
Cost & Interface: There is a 30 day trial for free. Purchased accounts start at 5$ a month and increase as the number of users is increased. Institutional discounts are available. The interface looks like a standard graphics program: tools can be selected, templates can be chosen from, and preset shapes offered via icon tool palettes.
Why I chose it: This software is a strong program. Flexible tools, great graphics, and easy to use.
Outstanding Feature: The graphics search is linked to yahoo and the pictures were great.
