Reflection on Visual Thinking

There is no denying that the visual language is not well accepted as an official mode of communications today. However, visual language does have a role in our society.

Musical note
Musicians do rely on visual language to communicate. The visual dialect is “musical score”. Composers get their message across through the note combination and arrangement shown on the score:



















Sign language

The deaf communicate by using some special finger signs. These are visual in nature:




















I think the problem of the segregation of graphics and text in communication is more prominent in the West. In the East, such as in China and Egypt, the characters were derived from symbolic symbols in the past. Here are some examples:












Ancient Chinese characters
















Ancient Egyptian characters


In the ancient time, people did communicate visually. But the drawback of the visual language is that it is very time-consuming to create even a very short message.

In response to “Polemics of Visual Thinking” by Adrian Van Allen, I would say that we should try hard to make a balance between using visual and text. Text isn't that evil, is it?

Reflection on Infographics

Our world is changing from text-based to visual-based. Decades ago, the newspapers were mainly text-based. But today, many people indulge in comics and TV. People begin to watch more but read less.

But in our education system, the students who are well trained on the reading and writing skills are more likely to succeed. Those who are good at drawing but not good at reading or writing are less likely to be successful in their academic life.

When more and more people begin to watch more and read less, does it mean that our society is downgrading? Or people now actually have been awakened to pick up again the graphicacy, the lost traditional wisdom our ancestors shared?

How ICT can contribute to the reborn of graphicacy? I think we should use Tablet PC wherever possible to facilitate our development of graphicacy. Email does not have necessarily to be text. Email can be picture. Here is an example:

Project Outline

Project Outline
By Daphne Chan and Chris Leung

Objective:
Show that learners can learn and retrieve information/knowledge better through visual and interactive learning instead of mere text-based learning.

Theory:
Mayer's cognitive theory of multimedia learning and Paivio's dual-code theory [1]

Method:
Using multimedia-based vs text-based instructional materials to compare their effectiveness in acquiring new knowledge by learners. The new knowledge can be a second language, mathematics, history, etc.

A simple quiz may be conducted following the learning session to compare the effectiveness of learning by two different approaches.

Deliverables:
Interactive learning objects will be designed and implemented with Flash to maximize the learning effectiveness based on the theories of Mayer and Paivio.

Reflection on visual presentation of information

I like the discussion on the squid pictures today. It is true that a picture worths a thousand words.

One improvement we can make with the latest technology is to add animation next to the description to make the information representation more lively. For example:

Adobe Reader 7.x is required to read the animation above.
