00 · IN THREE MINUTES
The answer in three steps
- 1 contains different products: recognizable landmarks, ordered routes and relations among places.
- 2Actively choosing and updating a route tends to recruit more spatial learning than following turn-by-turn commands.
- 3GPS is not uniformly harmful; interface design, user goals and habitual reliance determine what gets encoded.
01 · A MAP IS A SELECTION
A map is a selection
Scale, projection, labels and north-up orientation highlight some relations and suppress others. Readers remember an organized interpretation, not every street at its true metric distance.
02 · LANDMARKS ANCHOR EXPERIENCE
Landmarks anchor experience
Distinct buildings or intersections can be recognized without knowing how they connect. Landmark knowledge is useful but does not by itself provide a flexible route between unfamiliar pairs of points.
03 · ROUTES STORE SEQUENCES
Routes store sequences
Turn left at the bridge, then right at the square: route knowledge is ordered and often viewpoint-dependent. It can work efficiently while remaining brittle when a street is closed.
Changing the task changes what is encoded; no single representation is always best.
Landmark
Recognize notable places.
what04 · SURVEY KNOWLEDGE LINKS THE NETWORK
Survey knowledge links the network
A more map-like representation supports shortcuts and relative direction. It develops through exploration, attention to orientation and integration across multiple routes.
05 · TURN-BY-TURN GUIDANCE CHANGES THE TASK
Turn-by-turn guidance changes the task
If a device supplies every decision, the user can arrive with little need to update location or plan ahead. Studies associate heavier habitual GPS use with poorer performance on some self-guided spatial-memory tasks.
06 · INTERFACES CAN INVITE LEARNING
Interfaces can invite learning
Overview maps, landmarks, previewed routes and occasional choices can keep users engaged. Navigation support and spatial learning are design variables, not an all-or-nothing opposition.
