Design and Evaluation of Semi-Transparent Keyboards on a Touchscreen Tablet

Explore the design and evaluation of semi-transparent keyboards on touchscreen tablets in this 23-minute conference talk from the ACM International Conference on Interactive Surfaces and Spaces. Delve into research addressing the challenge of efficient text entry on tablets while maximizing screen space for applications. Examine three key experiments investigating the effects of transparency levels on usability, various design options for semi-transparent soft keyboards (STKs), and the impact of STKs on different text caret positions. Discover findings suggesting that STKs with 50% opacity offer balanced performance, well-designed STKs are suitable for both content reading and typing, and can achieve 90-100% of opaque keyboard performance. Learn about the potential for text carets to intrude into the STK down to the number row, offering insights for future tablet interface designs.
