Abstract
Reading unknown words in non-native languages can hinder comprehension or slow reading by requiring dictionary consultation. Existing solutions for faster lookup only work digitally or, in the case of printed text, require a separate display. To enable a more seamless reading experience in the latter scenario, we present ProTrans (Projected Translation), a projector-camera system that detects words users point to and projects their translations onto nearby surfaces. We compare three projection targets-paper, finger, and hand-and gather initial user feedback. Results indicate that projecting onto the back of the hand balances legibility and viewing comfort, supporting the feasibility of skin-based projection for translation tasks.
