 abstract = {Today's working society tries to integrate more and more impaired workers into everyday working processes. One major scenario for integrating impaired workers is in the assembly of products. However, the tasks that are being assigned to cognitively impaired workers are easy tasks that consist of only a small number of assembly steps. For tasks with a higher number of steps, cognitively impaired workers need instructions to help them with assembly. Although supervisors provide general support and assist new workers while learning new assembly steps, sheltered work organizations often provide additional printed pictorial instructions that actively guide the workers. To further improve continuous instructions, we built a system that uses in-situ projection and a depth camera to provide context-sensitive instructions. To explore the effects of in-situ instructions, we compared them to state-of-the-art pictorial instructions in a user study with 15 cognitively impaired workers at a sheltered work organization. The results show that using in-situ instructions, cognitively impaired workers can assemble more complex products up to 3 times faster and with up to 50% less errors. Further, the workers liked the insitu instructions provided by our assistive system and would use it for everyday assembly. },
