Study Notes

Course Information

Course title: CS3483 Multimodal Interface Design
Instructor: Prof. Raymond H.S. Wong
Room: Y6319
Phone: 3442-8624

Assessment

Examination: 40%
Project: 30%
Assignment: 20%
Tutorial: 10%
Passing grade: 50% coursework, 30% examination

Interface Design (Example 1) - Problems

Cache size expressed as a percentage of disk size
Minimum setting is 1%
Results in excessively large cache as hard drive capacity increases

Interface Design (Example 1) - Improved Design

Temporary Internet Files and History Settings
Check for newer versions of stored pages
Every time I visit the webpage
Every time I start Internet Explorer
Automatically
Disk space to use (Recommended: 50-250MB)

Interface Design (Example 2) - Problems

Large number of tabs makes it difficult to locate specific tabs
Placement of tabs does not follow a logical arrangement
Clicking back row tabs causes rearrangement

Interface Design (Example 3) - Information

Most Recently Used (MRU) file concept
Maintains a brief list of files recently accessed
Most people tend to return to same file upon application restart

Interface Design (Example 4)

Security questions: Who was your best childhood friend? In which city did your mother and father meet?
Easy to forget passwords
System asks for questions and answers when setting new password
Includes an "I forgot..." option for password retrieval

Case Study: Apple Quicktime

Designers aim for a simple interface mirroring physical devices
Problems: physical and interface environments don't match perfectly; applications inherit physical limitations
Thumbwheel design: volume control, originally for thumb input, difficult to identify
Drawer interface: holds advanced controls, button image doesn't show function, users might prefer constant access to certain controls (e.g., reverse/fast forward)
Improvements in new version: thumbwheel replaced by slider; reverse and fast forward controls moved to main window

Human-Computer Interaction (HCI)

Study of how people design, implement, and use interactive computer systems
Study of how computers affect individuals, organizations, and society

Requirements of HCI

Ease of use (GUI vs. command language, online help, documentation, training)
More powerful communications between users and computers (new interaction techniques, new input/output devices)
Universal access to information (large community of non-technical users, interfaces requiring minimal technical sophistication)
Information-access interfaces (must handle multimedia data)

Importance of HCI

Large proportion of design and programming effort dedicated to user interfaces (UI)
Good HCI design crucial for marketplace success and safety/usefulness/pleasure of computer-based systems
Good HCI design decreases costs and increases productivity by reducing errors, user disruption, task time, and support staff/training burdens

Foundations of HCI

Computer science, psychology, sociology, linguistics, artificial intelligence

History of HCI

Direct manipulation of graphical objects (Sketchpad, light pen, PARC's techniques, Direct Manipulation concept)
Windows (tiled/overlapping, NLS system, Emacs, Smalltalk)
Hypertext (Vannevar Bush, Ted Nelson, Ben Shneiderman's Hyperties)

HCI Applications

Mobile interface (different requirements for smartphones/tablets, conflicting requirements - tailoring to device and familiarity)
Multimedia search engine (alternative querying mechanisms like example-based specification needed)
Education (techniques for direct manipulation, learning environment design)
Information visualization (presentation of large data sets in graphical formats for trend exploration, heightened importance due to web information explosion)

Technological Trends

Wearable devices and ubiquitous computing (clothing/accessories, Apple Watch, embedding computers everywhere, MIT's Tangible Media Group)
Recognition-based user interfaces (keyboard/mouse, natural interfaces - speech, hand gestures, body movements)
Conversational interface (interfaces that respond intelligently to human conversation, keyword recognition and reassembly, template application)
3-D technologies (migration from 2-D to 3-D space, training/simulation/interactive exploration)

3-D Technologies

Revised 2-D notions (how to interact with info, select objects in 3-D space, navigate)
Objective: near-real-time interactivity

Additional Information

Head-Mounted Display (e.g., Oculus Rift)
Cave Automatic Virtual Environment (CAVE)
Data Glove
