In the near future, humans will be increasingly expected to team up with artificially intelligent (AI) non-human partners to accomplish organizational objectives ( Davenport and Harris, 2005 Bohannon, 2014). We discuss implications for the design of intelligent collaborative systems for the warfighter. Our results indicate that both assistant conditions led to higher performance over the no assistant condition, but the embodied assistant achieved this with less cognitive burden on the decision maker than the voice assistant, which is a novel contribution. The assistants made suggestions verbally throughout the task, whereas the embodied assistant further used gestures and emotion to communicate with the user. Participants were paired with a voice assistant, an embodied assistant, or no assistant. We present an experiment where participants engaged in an augmented reality version of the relatively well-known desert survival task. Here, we show that embodiment plays a key role in achieving that goal. In military settings, it is critical to design assistants that are, simultaneously, helpful and able to minimize the user’s cognitive load. Recent times have seen increasing interest in conversational assistants (e.g., Amazon Alexa) designed to help users in their daily tasks.
