Bidding for 2023 The bidding for MobileHCI 2023 is open. From 2019 and onwards, we have been paying special attention to the *diversity* (gender, cultural, economic, etc.) both in the organizing committee and in how the organisers plan to attract diverse audience to MobileHCI. Bidding Process MobileHCI is the forum that provides academics and practitioners a valuable place to discuss the challenges, potential solutions and innovations towards effective interaction with mobile systems and services. It covers the analysis, design, evaluation and application of human-computer interaction techniques and approaches for all mobile computing devices, software and services. Beyond mobile devices and services, the conference covers issues in the whole ecosystem of mobile, smart and embedded devices and the related services. The exact nature of a bid can of course include and seek to extend or focus this as the proposers envisage.
