An electronic device and method are provided for content modification in a shared session among multiple head-mounted display (HMD) devices. The electronic device determines emotional state information associated with a wearer of each of a plurality of HMD devices. Each HMD device renders media content in a computer-simulated environment and the emotional state information corresponds to a first portion of the rendered media content. The electronic device constructs an input feature for a first neural network based on the first portion of the rendered media content and the emotional state information. The electronic device selects, from a set of content modification operations, a first content modification operation based on an application of the first neural network on the input feature. Thereafter, the electronic device modifies the rendered media content based on the selected first content modification operation. The modified media content is rendered on at least one HMD device.
