While low-cost smartphone-based mobile VR (MVR) improves access to extended reality (XR) technology, it lacks the interaction capabilities of high-end devices. Following PRISMA 2020 methodology, we present a survey of both established and emerging MVR interaction techniques for travel, selection, manipulation, and system control. We reviewed literature from four databases published between 2011–2025 that reported evaluations of MVR interaction techniques. We filtered an initial set of 1041 publications to 64 articles and synthesized the current state of MVR interaction, focusing on cost-accessible approaches. We found many effective low-cost emerging selection and travel techniques, but low-cost object manipulation techniques remain problematic. Acoustic sensing offered superior 3D interaction performance than other sensing modalities while keeping cost low. Our findings inform a novel taxonomy of emerging MVR interaction techniques. We further present a toolkit supporting the design of cost-accessible XR interactions. Our findings underscore practical advantages of DIY approaches to future standalone XR applications developments.
