This paper introduces Eye-Shield, a mobile projector-camera prototype designed for the purpose of protecting people from being accidently blinded with a handheld projector. Since they might be used regularly in public space, mobile projectors can be seen as an intrusive technology. The emitted projector light can easily annoy bystanders which might lead to negative social consequences, particularly, if the light shines directly into one's face. The proposed prototype uses a camera attached to a mobile projector to detect faces within the projection area in order to block out the part of the image that would otherwise be projected onto a human face.
