Use Cases of HCI
- Smart home : Smart homes refers to home amenities that have been fitted with communication technology enabling some degree of automation or remote control. It includes control of air conditioning, heating and lighting through voice activated commands or mobile app. Home security systems are also fitted with communication technology to alert the residents in case of burglary.
- Biometric Sensors : Biometric sensors are the use of human biometrics in various technological applications. It can be used in access controls for example granting access to a computer network or security system.
- Autonomous vehicle : An autonomous vehicle is one that can drive itself. Tesla is a company which pioneered the engineering of autonomous driving vehicles. It has advanced autopilot technology which allows real time navigation updates.
- Virtual assistants : Another innovation in this era is the intelligent virtual assistant or intelligent personal assistant. It is a software agent that can perform task or services or an individual based on commands or questions. These virtual assistants can interpret human speech and respond via voices.
- Smart phones for Visual Disabilities : There are some features present in smart phones that make the life of people with disabilities easy. Voiceover is a screen reader which basically means that your phone will talk out loud and tell you what’s on the screen. User can control it with certain touch gestures. There are some other features also like Magnification.
Introduction to Human Computer Interaction (HCI)
HCI (Human Computer Interaction) is a field of study that refers to communication between the human user and a computer system. Here interface refers to a medium or interaction between the computer and the end user. It is also known as CHI (Computer Human Interface) or MMI (Man Machine Interaction). It is concerned with design, evaluation, and implementation. It is used to provide a user-friendly environment.
Important Topics for Human Computer Interaction (HCI)
- Objective
- History
- Input and Output devices
- Interaction Styles
- Use Cases of HCI
- Application of HCI in different domains
Objective
Human uses digital devices to perform various activities. HCI is to design a systems in such a way that make them efficient, stable, usable and attainable. Lack of communication can result in poor designed user interfaces. It provides a ways to reduce design time through various task models. There are some disciplines contributing to HCI.
Computer Science
Computer science is a field of computation and information. Computer science plays a crucial role in modern development of HCI. Smart Television, Voice assistant, AR/VR technology and gaze detection are some of the technology exists in modern world, that are running our day to day life.
Cognitive Psychology
It is a field of HCI which identifies how human interact with systems. It includes Language based interaction, a set of rules are provided to the system. Based on that rules we create our model. It also includes Human motor skills, where we identifies physical characteristics of user and based on that characteristics we create our model.
Fine arts design
An artistic way of thinking always produce creative ideas. E-books and novels, digital drawings, video games are some of the applications of fine arts contributing to HCI.
