Lecture 5 - Wearable Outputs Flashcards
Wearables have limited interaction capabilities and limited
display capabilities due to the small screen sizes possible
When we don’t have enough screen size what can we do to convey more information through a wearable?
Offload the information to other modalities e.g. sound , haptic feedback (vibration for example)
Information we convey through other modalities must be?
understandable, perceivable in mobile contexts (as we are focusing on mobile wearables and devices)
What are the benefits of using audio as an output modality?
easy to deliver audio feedback
What are the drawbacks of using audio as an output modality?
social acceptability
if it is noisy it may not be possible without headphones
What are haptics?
output(s) that stimulate the sense of touch
What is the most common haptic to be used as an output modality?
vibration
What is vibration great for?
representing urgency
What is vibration not so great at?
putting across emotions and any other information pretty much
What is a challenge with haptics?
How can we represent info?
How can user know what the haptic represents?
What are projected screens?
A projector providing larger display space for a device, making it easier to interact with and requires less focus. These can be integrated into many form factors (e.g. glasses project onto arm, ring projects onto arm)
Drawbacks of projected screens?
unfamiliar
tech not ready yet
What does the future hold for wearables?
- implanted wearables
- smart tattoo wearables
