We introduce the TextTearing technique for in situ expansion of inter-line whitespace and pair it with a lightweight interaction for margin expansion as a way to address this problem. The full system leverages the dynamism of digital documents and employs a bimanual design that combines the precision of pen with the fluidity of touch. Our evaluation found that a simpler unimanual variant of TextTearing was preferred over direct annotation and margin-only expansion. Direct annotation in naturally occurring whitespace was least preferred.}, publisher = {ACM}, url = {http://approjects.co.za/?big=en-us/research/publication/texttearing-opening-white-space-for-digital-ink-annotation/}, pages = {107-112}, isbn = {978-1-4503-2268-3}, edition = {Proceedings of the 26th Annual ACM Symposium on User Interface Software and Technology}, }
