AdHocProx: Sensing Mobile, Ad-Hoc Collaborative Device Formations using Dual Ultra-Wideband Radios

Notes for adhoc annotations on second device

Inside-out sensing to detect presence and relative orientation of nearby devices.

Cross-device interaction scenarios for dynamic, ad-hoc device formations Dual DW3000 Ultrawideband (UWB) radios

Capacitive grip sensors Device-integrated inertial measurement unit (IMU) ESP32 microcontroller Figure 1: AdHocProx leverages multiple inside-out sensing modalities (including dual Ultra-Wideband radios, capacitive grip sensing, and fused inertial orientation) built into a device such as a tablet to detect presence, relative position, and device-motion gestures towards other nearby mobile devices. AdHocProx achieves this without recourse to externally-anchored beacons, central orchestration, or even reliance on local WiFi connectivity. This unlocks a number of cross-device interaction scenarios for highly dynamic, ad-hoc device formations outside of infrastructure-heavy "smart room" or lab settings.
