The 15th International Display Workshop (IDW2015) took place from 9th to 11th in December at Ootu in Japan. IDW2015 is one of renowned conference about optical technology and applications with about 1,200 participants from worldwide. In this conference, we gave an oral presentation titled "An Applied Method for Wearable Device with Assortment Work in Logistics", which enables workers to work more efficiently by adapting wearable device in warehouses.

Recently, Hitachi Transport System, Ltd. and other Hitachi group companies try to adapt wearable device in their business. In this presentation, we presented an example of adapting wearable device to assortment work in warehouses. Assortment work is that workers assort products to indicated place. Currently, workers use a device called as handy terminal during the work. It is useful, but there is one problem that workers always work with only one hand. Therefore, we adapted glass type wearable device called as smart glasses and tried to achieve hands-free work style.

Generally, handy terminal has two main functions; one is direction of work, the other is scanning barcode label. We need to provide these functions with wearable device system. First, we adapted smart glasses to show the direction to workers with hands-free. To use smart glasses efficiently, we proposed a useful display method. In this method, only limited requisite information was displayed on smart glasses and workers can understand their current position and next working place in a short time. Second, we adapted glove type barcode reader. In this system, when workers scan a barcode correctly, the smart glasses pointed out next direction immediately.

We developed assortment work support system with wearable device with the features described above. Furthermore, we introduced the system to a warehouse and workers can work their daily work with the system shown in Photo 2. The result showed 15% cost cut effect in comparison with handy terminal.
