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.
