  Inside-out tracking is growing popular in consumer VR, enhancing
accessibility. It uses HMD camera data and neural networks for effective hand
tracking. However, limited user experience studies have compared this method to
traditional controllers, with no consensus on the optimal control technique.
This paper investigates the impact of control methods and gaming duration on VR
user experience, hypothesizing hand tracking might be preferred for short
sessions and by users new to VR due to its simplicity. Through a lab study with
twenty participants, evaluating presence, emotional response, UX quality, and
flow, findings revealed control type and session length affect user experience
without significant interaction. Controllers were generally superior,
attributed to their reliability, and longer sessions increased presence and
realism. The study found that individuals with more VR experience were more
inclined to recommend hand tracking to others, which contradicted predictions.
