Cache Size Based on Disk Size
Cache Size Based on Disk Size
The cache size setting based on a percentage of the disk size can lead to an excessively large cache as the hard drive capacity increases.
Improved Cache Size Setting
Improved Cache Size Setting
Instead of using a percentage, cache size should be expressed as a fixed value or using a slider with a clear indication of the size.

Study Notes
Course Information
- Course title: CS3483 Multimodal Interface Design
- Instructor: Prof. Raymond H.S. Wong
- Room: Y6319
- Phone: 3442-8624
- Email: [email protected]
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
