Gesture technology is entering our lives
What is a gesture?
What kind of gestures are we interesting in?

Pointing gestures
Semantic gestures
● Gestures with an associated meaning● No need for an additional GUI● Potentially more efficient
Challenges● Presumably influenced by local cultures● Some cultures might be more predisposed to the use of
gestures than othersSemantic gesture for mission control on a Mac
The UX Fellows Gesture Study (video)
The UX Fellows Gesture Study
Which semantic gestures would people from various cultures spontaneously use to control consumer electronic devices?
● Country differences?● Country clusters?● Underlying metaphors?● Acceptance?
We compared spontaneous gesture behavior in 18 countries.

Sample
Persons who are able to imagine a gesture-control scenario for a TV.
● Regular usage of a recent HD flat TV (max. 5-6 years of age) and other CE devices and services
● High interest in consumer electronics● Regular usage of a touch device● No Xbox Kinect and gesture-enabled TV users● Potential buyers of international "premium" CE brands
(no national, retailer or "no name" brands)

Direct vs. abstract gestures
We observed two kinds of gestures.
● "Direct" gestures o strongly influenced by touch devices
● Abstract gestures o basis in language, iconography and metaphorso associated with more complex taskso lower intercultural commonality

General acceptance
● Our 360 tech-savvy participants responded very positively to the idea of semantic gesture input for TVs.
"fun to use", "convenient", "coolness factor"● Participants would like to use gestures to control other
devices as well (e.g. audio).
Operation
Many participants felt that voice and sound could be a good support for gesture input.

Can the TV hear me?

Typical concerns of users
● Learning and retention of gestures (but: would be easy if based on implicit behavior repertory)
● Sensitivity and accuracy of devices● Interference by other gestures in the room● Compatibility with lean-back disposition
Conclusions
Conclusions
1. For basic CE commands a common language for semantic gestures already exists across cultures.
2. More complex commands could be realized by either
a. customizing these gestures for each individual market
b. customizing individually
c. proposing a set of semantic gestures that need to be learned (the study provides some suggestions)
d. switching to pointing gestures in combination with a GUI
3. It is necessary to consider cultural differences at a country level when it comes to designing advanced gesture control for globally marketed devices.
