受先前作品的启发，显示了AR自我化身的前景-为用户提供增强的自我化身，我们调查了化身用户的末端效应器（手）是否改善了他们在近场，避障，对象检索任务上的交互性能，其中用户的任务是从非目标障碍物的领域检索目标对象进行多次试验。我们雇用了一个3（增强手表示）X 2（障碍物密度）X 2（障碍物的大小）X 2（虚拟光强度）多因子设计，操纵覆盖在用户的真实的手上的增强的自我化身的存在/不存在和拟人化保真度，作为跨三个实验条件的受试者之间的因子：（仅使用真实的手）;（2）图标增强化身;（3）现实增强化身。结果表明，自我化身提高了互动性能，并被认为是更有用的化身的拟人化保真度无关。我们还发现，用于照明全息图的虚拟光强度会影响一个人的真实的手的可见度。总的来说，我们的研究结果似乎表明，交互性能可能会提高时，用户提供了增强的自我化身的形式的AR系统的交互层的视觉表示。
Inspired by previous works showing promise for AR self-avatarization - providing users with an augmented self avatar, we investigated whether avatarizing users' end-effectors (hands) improved their interaction performance on a near-field, obstacle avoidance, object retrieval task wherein users were tasked with retrieving a target object from a field of non-target obstacles for a number of trials. We employed a 3 (Augmented hand representation) X 2 (density of obstacles) X 2 (size of obstacles) X 2 (virtual light intensity) multi-factorial design, manipulating the presence/absence and anthropomorphic fidelity of augmented self-avatars overlaid on the user's real hands, as a between subjects factor across three experimental conditions: (1) No-Augmented Avatar (using only real hands); (2) Iconic-Augmented Avatar; (3) Realistic Augmented Avatar. Results indicated that self-avatarization improved interaction performance and was perceived as more usable regardless of the anthropomorphic fidelity of avatar. We also found that the virtual light intensity used in illuminating holograms affects how visible one's real hands are. Overall, our findings seem to indicate that interaction performance may improve when users are provided with a visual representation of the AR system's interacting layer in the form of an augmented self-avatar.
