While mobile phones made a significant evolution in recent years from single-purpose communication devices to multi-purpose devices, the fundamental design of phone call applications did not evolve accordingly. While its implementation leveraged from new hardware and software capabilities, the fundamental decisions people are able to make when they receive a call did not change. Currently, when a call comes in, a modal dialog opens where the callee can either decline or accept the call. A recent study found that the current user interfaces of phone call applications (phone UIs) often lead to an increased overhead when application usage is being interrupted by phone calls . In this paper, we revisit phone call UIs for multipurpose smartphones. We contribute a new design space for mobile phone call UIs, going beyond the simple accept-or-decline dilemma. We present a prototype implementation and discuss open challenges.
