Abstract: Embodiments herein use multiple different transmission modes of a line-of-sight (LOS) communication system (e.g., an infrared (IR) or visible light communicate system) to simulate user actions that correspond to different distances—e.g., a melee attack versus a ranged attack. A toy device may include various sensors that detect user motion which is then used to identify a user action. If the user action is a melee attack, then the attack should affect only targets that are close to the toy device. To simulate this difference between user actions, the toy device uses a first LOS transmission mode which may have a limited range to send an instruction to a target device. Conversely, if the user action is a ranged attack, then the toy device uses a second LOS transmission mode which has a greater range than the first LOS transmission mode to send the instruction.
