Essays on Human Computer Interaction

INTRODUCTION

This project is undertaken to find out how natural user interfaces can enhance the use of devices for illiterate people. This is given the fact that the rate of illiteracy is an issue of concern in South Africa and the world over. This chapter will focus on previous research which have been carried out and the gap that is lacking in this field. It is important to understand the work that has been carried in order to research on what is still lacking in this field.

What is Natural user interfaces?

A natural user interface (NUI) is a system for human-computer interaction that the user ...

An interface is the point of contact between two systems. This paper deals with the dynamics involved in the contact between human beings and computers. Human-computer interface concerns itself with the multifarious methodologies and the numerous processes which are involved when designing computer interfaces. It also involves the methods used in implementing, evaluating and comparing the various human-computer interfaces . One of the long term goals of the human computer interface is to design a wide range of systems which either do away with or minimize what humans intend to cognitively achieve by interacting with the computer and the computer’s ...

Introduction

The application of metaphor has important function in human computer interaction (HCI).It can be used as a device to aid users appreciate new or strange technologies and as a tool to direct the design process. The creators of fresh computer based instruments face the same issues of design just like those in human computer interaction. It is widely used in various type of interface designs ranging from computer interfaces, gesture controlled instruments, mobile phone interfaces, smart phones and tablets, other structures of mental model, autonomous systems, assistive devices and any other interface design that is based on users’ mental model. ...

Explain haptic feedback, describe its key uses, and explain why it is needed

Haptic feedback/ tactile effect is a technology which recreates the event of touch by giving vibrations, or motions to the user. It is a technology which is commonly used in human computer interface in today’s computing systems, including smart phones. Haptic feedback does the same thing for the sense of touch as does computer graphics for the sense of vision. Haptic technology lets us investigate how the human sense of touch works by creation of carefully controlled haptic virtual objects. These are used to systematically investigate human haptic capabilities. These research tools help us understand how touch and its underlying ...

Human computer interface has continued to advance with the advancement in technology. The design of graphical user interface has continued to advance to accommodate the natural feedback from the user. These advancements have made it easy for the user to communicate to the computer and the computer to communicate to the user. Advancement in human computer interface such as the use of touch-screen and motion detectors have made for the user to work more quickly while reducing user stress.

Haptic feedback

Haptic refers to nonverbal communication, which involves the sense of touch. This requires that the system sends feedback to the ...

Introduction

Whether or not the use of technology in the college classroom brings more harm than good, is debatable. While technology has been a central factor in many sectors including business and education, this debate has taken a center stage, with proponents of either side pushing to have their views heard. This paper prominently addresses the pro-technology side of the argument, followed by brief rebuttal and counterarguments.

The Argument for Technology in College Classrooms

- According to Osorio et al (2005), “the human computer interaction makes communication, a central factor in education, easier”. The human computer interaction makes the conveyance of information easier through eliminating barriers associated with human ...

In the 21st century, the world is changing tremendously; this is brought about by the invention and innovations in the technological arena. In fact, today’s technological environment has been changed to be a digital world. Most of the things that relate to technology, which are used by human beings globally have been digitalized. The lifestyle that people lice and activities they undertake in the technological environment makes it a digital world. In the digital world, many things have been affected, including, education, communication, infrastructure, security, medicine, business, and entertainment; hence, what makes today’s technological environment a digital world is almost ...
