Gestural Query Specification Arnab Nandi, Lilong Jiang, Michael Mandel Presented by Himel Dev
Human Database Interaction Extremely helpful for driving novice users away
Human Database Interaction [2] Allows fixed format questions, nothing beyond
Human Database Interaction [3] Everyone loves visualizations, but micro-level info missing
Gestures Natural Interaction Continuous Interaction Direct Manipulation Accessibility Overwhelming
Gesture Articulation G = {p1, p2, , pn} pi = <t, l, m> t : timestamp l : locational information in the interface m : metadata associated with point and time Continuous feedback
Query Paradigm Query Intent Space of articulated queries User goes from vague to specific intent Intent transition Query Context Direct Manipulation Session of multiple Query Intent Transition Intent Feedback
Gesture Vocabulary [Alternative] https://www.youtube.com/watch?v=ZdJgUDB oB4M
Gesture Recognition Classification Proximity (State-of-the-art) Compatibility (Semantically meaningful queries) Maximum entropy
Experimental Study Mostly user study within Subjects Same group of subjects serve more than once No catching-on effect (convergence) They claim to avoid all bias Considerations Fatigue Effect Carryover Effect Consistency
Back to HDI What are our expectations? Interactive Expressivity Supports 3 user groups (Aditya s categorization) What more? Possible solutions Query recommendation Natural language feedback
