Transcript of UPA Presentation

Introduction Gesture Research Goal
Have 40 participants in each of 9 countries to create gestures for 28 actions Challenge #1
Ensuring repeatability Challenge #2
Recording gestures Gestures are used in an ever increasing number of products Some gestures vary by culture Challenge #3
Classifying consistently Series double tap; curve around object 1. Analyzed the top-generated gestures, and the very infrequent gestures
Sorted gestures created for each action by frequency and statistically determined the top-generated gesture(s) and the very infrequent gestures

2. Analyzed for cultural differences - conducted 3 primary analyses
Did one country use a particular gesture more than another?
Did one country use a particular gesture type (direct manipulation vs symbolic) more than another?
On visual inspection, did a pattern of responses emerge?

3. Analyzed for Novice vs Experience differences - 2 analyses
Computed agreement scores for Novices and Experienced participants
On visual inspection, did a pattern of responses emerge?
Dan Mauney Method Data Analysis Results Results 1. Analyzed the top-generated gestures, and the very infrequent gestures

2. Analyzed for cultural differences - conducted 3 primary analyses
On visual inspection, did a pattern of responses emerge?

3. Analyzed for Novice vs Exerience differences - 2 analyses
On visual inspection, did a pattern of responses emerge? There was a higher agreement on gestures for actions that could be performed through direct manipulation and lower agreement on gestures for actions that were more abstract in nature Discussion 1. Most of the variability in participant responses was not based on culture
China's use of symbolic gestures was the primary exception to this finding
Good news for designers of global products

2. Back, Forward, Scroll Up, and Scroll Down exhibited the largest pattern of differences
that is most likely due to experience with finger-driven touchscreen interfaces
Few other differences found between Novices and Experienced participants

3. When a gesture to elicit an action was not immediately identifyable, participants
generally wanted to tap on the screen to bring up a menu

4. For actions with no clear top gesture other than tap, a detailed examination of this dataset would be a strong first step toward identifying an appropriate gesture.
One pattern we noticed when examining these ourselves is that participants often used the first letter of the action or drew the familiar windows icon when trying to create a shortcut Potential Follow-on Research Take the top gestures generated by participants and provide
them to a new group of participants in a survey as multiple
choice options and request a large number of participants
in each country to select the gesture that makes the most
sense to them

Once participants have made all selections, allow them to go back and change previous answers after considering the gesture set as a whole. Allow iteration until participant feels the set is ideal.

• Cultural differences in the use of gestures?

• Differences between experts and novices?
A cross-cultural gesture set Discussion Gesture set This study aims at helping designers understand how users expect to interact with a gesture-enabled touchscreen.

Therefore, we took an initial approach to suggest a gesture set for the 28 investigated actions ... with a few caveats:

Gestures were collected independently
Gestures are interdependent and need to be evaluated as a complete set
A lo-fi prototype was used to collect data >> no system feedback >> no learning and adaptation from users >> but intuitive behaviour unaffected by the system's response

Did one country use a particular gesture more than another?
-->For the top 38 gestures (used by more than 40 people), there was no significant difference across country in their use of those gestures

Did one country use a particular gesture type (direct manipulation vs symbolic) more than another?
-->Country was significant at the p<0.001 level
