Abstract: A non-transitory computer-readable storage medium including instructions for distributing tasks between a handheld intermediary processing device (HIPD) and communicatively coupled devices is disclosed. The instructions cause one or more processors to, while a HIPD and a head-wearable device are communicatively coupled and share operational data for performing one or more computational tasks, identify one or more back-end tasks and one or more front-end tasks associated with performing the one or more computational tasks. The instructions further cause performance of the one or more back-end tasks at the HIPD including updating the operational data to create updated operational data. The instructions further cause performance of the one or more front-end tasks at the head-wearable device using the updated operational data such that a representation based on the one or more computational tasks is presented to the user by the head-wearable device.
