# Affordances & Feedback
Good Affordance| Bad Affordance

Well-designed objects have affordances
- Clues to their operation that are readily apparent
- Often visual, but not always (e.g., speech)
- Allows and promotes certain actions

???
Opportunities to act which are readily apparent to the user ... and
appropriate to the user’s abilities

relationship of affordence and feedback

Form “affords” certain actions and makes that apparent

# Model of Mental Models

![:img A box showing the design (white) and actual function (blue missing
a little bit of the white) with a grey circle added in the center
labeled "Frequently Used (Well understood) Part of System
Functionality" a dark blue cloud labeled "Occasionally Used Part of
System Functionality" around the user's well understood region and
another cloud further out with errors (regions outside the blue system
box) labeled "Users full model of what the system does",100%](img/final/mental6.png)

???
- Where are the gulf of evaluation and gulf of execution in this
  image?  Gulf of execution is the user 'error' region (user requests
  function the __system DOESNT HAVE__), gulf of
  evaluation is when the user __doesn't realize the system HAS a
  functionality__. 
  
- How does undo help the user bridge them?

Capture and Access

Adaptive Services (changing operation or timing)

Novel Interaction

Behavioral Imaging

General Solutions for Data Collection and Response

Challenges?

???
- Battery
- Raw sensors not behavior data
- Not the sensors we always want
- Computational complexity
- Latency in communication
- Basic software framework to support apps that can adapt to user behavior
- Apps that drive innovation
- How people use phones
