GestureDB: Querying Beyond Keyboards

Database Architecture for Next-Generation Interfaces

Computing devices that use non-traditional methods to interact with data are becoming more popular than those that use keyboard-based interaction. Applications and query interfaces for such devices pose a fundamentally different set of workloads on the underlying databases. We characterize these differences and show how today's query representation and evaluation techniques are not well-suited to these new non-keyboard interaction modalities. We propose a new database architecture to address these issues.
