Study Notes
Introduction
- Breadcrumbs for navigation helps track pages visited.
- Web advertising can be invasive and annoying.
- Website design should consider: Where am I? Where can I go? What’s here?
Mobile Interfaces
- Handheld devices like phones and fitness trackers are used in everyday life.
- Tablets can be used in mobile settings.
QR Codes
- QR Codes are machine-readable codes.
Fitts' Law
- Predicts the time it takes to select a target based on its size and distance.
Graphical User Interfaces (GUIs)
- The original GUI was called WIMP.
- Consisted of: Windows, Icons, Menus, and a pointing device.
- Windows enable viewing more information and performing tasks.
- Scroll bars within windows enable viewing more information.
- Multiple windows can make it difficult to find desired windows; techniques that help include listing, tabbing, and thumbnails.
Touch Interfaces
- Provide fluid and direct styles of interaction involving freehand and pen-based gestures.
- Size, orientation, and shape of touch displays can impact collaboration.
- Finger flicking is fast for scrolling through wheels, carousels, and bars of thumbnail images or lists of options.
- Typing on virtual keyboards is more cumbersome, error-prone, and slower than physical keyboards.
Gesture-Based Systems
- Gestures involve moving arms and hands to communicate.
- Use camera recognition, sensor, and computer vision techniques.
- Gestures must be presented sequentially for understanding.
Haptic Interfaces
- Provide tactile feedback using vibration and forces applied to a person’s body.
- Can be used to simulate the sense of touch between remote people.
- Ultrahaptics uses ultrasound to create the illusion of 3D shapes.
Multimodal Interfaces
- Provide enriched user experiences.
- Multiply how information is experienced and detected using different modalities (touch, sight, sound, speech).
- Support more flexible, efficient, and expressive ways to interact.
- Most common is speech and vision.
- Can be combined with multi-sensor input to enable other aspects of the human body to be tracked (eye gaze, facial expression, lip movements).
Brain-Computer Interfaces (BCIs)
- Provide a communication pathway between a person’s brain waves and an external device.
- Person is trained to concentrate on the task, for example, moving a cursor.
- Work through detecting changes in the neural functioning in the brain.
Smart Interfaces
- "Smart" refers to having some intelligence, connected to the internet, and other devices.
- Context-aware; understand what is happening around them and execute actions.
- Human-building interaction; buildings designed to sense and act on behalf of inhabitants.
Which Interface?
- The choice of interface depends on task, users, context, cost, and robustness.
- There is no single "best" interface; each has its strengths and weaknesses.
