The document discusses Human-Computer Interaction (HCI), including its history, current trends, and future technologies. It covers the evolution of interfaces from early methods to modern and future applications, particularly the role of HCI in aiding individuals with disabilities through multimodal systems. It highlights the goals, misfortunes, and potential of HCI in various fields like intelligent homes, gaming, and e-commerce.
Human computer interaction with Nalaemton
- 1. Decoding The Future Technology… By: S. Nalaemton, III year CSE Dept., DMICE.
- 3. HCI involves • The study • Planning • Design • Uses of interaction between user and the computer. Three common interfaces: • GUI • VUI • gUI
- 4. The History of HCI The term HCI was popularized by • Card • Moran • Newell The first book on HCI : ‘The Psychology of Human-Computer Interaction’ (1983). The terms’ first known use was in 1975.
- 5. Yesterday…Today and Tomorrow!!! Scenario Input Output Early days • Connecting wires • Paper tapes • Punch cards • Keyboard • Lights on display • Paper • Teletype Today • Keyboard • Cursor keys • Mouse • Microphone • Scrolling glass teletype • Character terminal • Bit mapped screen • Audio Future • Data gloves + suit • Computer jewellery • Natural language • cameras • Head mounted displays • Ubiquitous computing • Autonomous agents • Multimedia
- 6. The misfortunes of HCI so far… Poorly designed Human-Computer Interfaces leads to many problems. Some of the fatal failures of HCI include: • Three Mile Island accident • Aviation failure The designs are conceptually fantastic but unfortunately had undesirable results.
- 7. Goals of HCI • Methods for implementing interfaces. • Techniques for evaluating and comparing interfaces. • Developing new interfaces and interaction techniques. • Developing descriptive and predictive models and theories of interaction. • Design systems that minimize the barrier between human mental model and the computer.
- 8. Applications of HCI • Intelligent homes • Intelligent offices • Driver monitoring • Intelligent gaming • E-commerce • Helping people with disabilities

- 12. Multimodal Web Interface Bharati: A internet user interface for both language and computer illiterate people: text, speech, icon. Bharati Chopra: Iconic module for the people unable to read/write in their mother tongue. Bharati Dhwani: Speech based module for those who can speak but not reading/writing ability in their mother tongue. Bharati Akshar: Text based module for the user unable to use English.

- 14. Helping People with disabilities •A good application of multimodal systems is to address and assist disabled people. •In this system users can interact with machine using voice and head movements. •Two modalities are used and both are active continuously: speech and head movements. •Speech provides the needed information about the meaning of the action that must be performed with an object selected by the cursor. •The head position indicates the coordinates of the cursor on the screen at the current moment.
- 15. Natural User Interface Advantages No training required Can be quicker than keyboard entry Hands-free Can be used by the disabled Disadvantages Emerging technology – still contains “bugs” Difficulty in dealing with homonyms Difficult to recognise all the different ways of saying things (and regional dialects) Artificial languages are often more precise
