A fascinating aspect of human computer interaction

Hi Guys again!!!
Today early in the morning I was thinking how interesting is the  aspects that we can get learn through HCI principles.


A fascinating aspects of HCI is that how the HCI develop through years and how people can communicate with products and things effectively. An example can be how the people learn how to use the computer and how through all this years are developing so fast. The first time that I have listen about HCI I don't really know that have so big history and affordance

The following diagram shows some fields that affected by HCI and shows the growth of the HCI field.

This diagram show us that the HCI improve the communication between humans. Also how important is for people to communicate effectively

I was really love to search interesting blog so I found some for you:

Good and Bad Design Products

Hi guys am posting again because I want to show you some examples of good and bad design of products. It very important a good design because as designer we want from users to enjoy the use. I found this results through the preparation of an presentations.

 The first product that I have to show you is the refrigerator that you can see above.
this is an example of bad design because both side had handles and only one of them open the refrigerator. As a result of that the user they did not know which site can open the refrigerator.
The site that can open the refrigerator must be clear to the user, and also must be visible which handles must use in order to open it.
Some suggestions that can make the refrigerator an example of a good design can be that the handles must exists only on the side that is open the refrigerator. Also the handles can be in front of the door and not in the side.

 The second product that I found as good design example it is the keyboard above.

This product all of as we use to use it hundred times per day. Do you never consider why this happen ? The keyboard it an ergonomic and usable product. It is a good design example because all their controls are visible, Also all their controls are clear.

Human Computer Interaction

Welcome to Human Computer Interaction Field

Hello everyone I want to welcome you all and to say thank you that you choose to follow my blog. The main aim of this blog is to consider different fields that includes on Human Computer Interaction Flied!
Human Computer interaction it is the way that people interact, react and communicate in their everyday and working life.
The goals of interaction design are first to create usable products and secondly to involve users in the design process( it is focus on user experience).

The HCI (Human Computer Interaction) focus on:

• Enjoyable to use the product.
• Easy to learn how to use it.
• And effective

In order to create an interactive product the designer has to follow some design principles:

• Visibility: Visibility is the degree to which a particular object is easy to discover or locate. Sometimes an invisible control can make the device more difficult to use.(Preece, Rogers, & Sharp, 2015)
• Feedback: Feedback is that the device must be designed to provide feedback to the users to inform them that their action was successful or not, to ensure them that they know what to do next or how to proceed. Sending  information back to the user about what have be done.(Preece, Rogers, & Sharp, 2015)
• Constraints :  Constraints refers to determining ways of restricting the kinds of user interaction that can take place at given moment. Helps  user to use with the right way the product by physical objects that contain constraint things.(Preece, Rogers, & Sharp, 2015)
• Consistent: Consistent refers to designed interfaces to have similar tasks. the benefit of consistent interfaces are easier to learn and use. (Preece, Rogers, & Sharp, 2015)
• Affordance: Affordance describe the attribute of an object that allow users to know how to use it. (Preece, Rogers, & Sharp, 2015)
