5 Reasons Why People Use This Language
There are a lot of programming languages both in the real world and
in the academic experimental world. Everybody knows the common
function which Professor Turing defined among the languages.
Although almost all programming languages which are used as a
production can be ultimately written in a single language, we tend
to use specific languages for some reasons.
- Our project has used this language.
- Our project needs a specific library written in this language.
- We're excel at this language.
- A specific functionality of this language is absolutely
effective on our project.
- The syntax of this language is good.
This order means the order of impact. Yes, unfortunately the syntax
matters the least.
Note that only (3) and (5) are independent on a specific project,
and (3) can be said a consequence of (5). Therefore it is deducted
that (5) is worth studying.
Human Computer Interaction
According to wikipedia,
human computer interaction, also known as the study of human
interface, is defined as the study of interaction between people
and computers. In other words, human computer interaction is the
combination of computer science, behavioral sciences, design and
several other fields of study. The goal of HCI (Human Computer
Interaction) is to improve the interactions between users and
computers by making computers more usable and receptive to the
user's needs.
I think that the biggest challenge of this field is how to evaluate
the goodness of a given hypothesis. We cannot deductively prove the
new theory certainly makes a system more usable easily. We cannot
numerically measure how the new theory certainly improved the
usability easily.
Programming Language as Human Computer Interaction
Remember the conclusion of the reason why we use a specific
programming language, which is previously described: "because the
syntax of this language is good." Here we have to consider how to
evaluate the goodness of the language. It is difficult for language
designers and users to objectively explain how good their language
syntax is. This circumstance is highly similar to the issue of
HCI.
For example, some people agree the following example: Ruby is
better than Java because of the simple "Hello, world!" sample
obviously.
# Ruby
puts 'Hello, world!'
/* Java */
class HelloWorld {
public static void main(String argv) {
System.out.println("Hello, world!");
}
}
It is easy for me to disagree the opinion. I don't think I have to
declare the reasons here because you can presume easily.
So, how can we evaluate the goodness of language syntax without any
controversial counterargument? What points of view are desirable
for the purpose? This issue is worth studying.
Conclusion
Programming language has aspects of the study of human computer
interaction. I showed only the importance of syntax as one of
aspects, but there are some other features include being able to
complete by editors and type system for human aid. It turns out
that it is good to improve it with the similar ways of previously
used in HCI studies.
Other Miscellaneous Comments
According to ACM, HCI is defined as "a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them."
In short, HCI is for implementation of interactive computing system.
Whereas my view on this entry is for implementation of implementation of interactive computing system.
It can be said as higher order HCI.
