Visual Sort Assist

Visual Sort Assist

Improve work efficiency for manual sorting


Visual Sort Assist (VSA) is a logistic solution that dramatically transforms the process of manual parcel sorting. It combines object recognition and projection mapping technology to reduce the judgement time for sorting parcel destinations.

3-Minute Movie


Even now, many logistics workers are manually sorting parcels. It takes time to sort them into destinations because the workers have to read the label for each parcel and recognize the destination. Managers also need to train the workers to understand the labels. It's a considerable challenge for managers to improve sorting efficiency.



Visual Sort Assist projects a distinguishing color and large symbol onto a moving parcel for the destination referred from scanned barcode. Workers simply look at the symbol for sorting.

Reading the labels
It takes time to visually check the label, and workers have to learn specialized knowledge to judge parcel picking.
Using Visual Sort Assist
Easy visualized marking used for picking. Significant training is not required. And work improvements can be achieved.
  • - Installs to the existing sorting facility as an option, saving labor and lowering costs
  • - Improves the efficiency of the sorting operation
  • - Reduces picking errors
  • - No training required for workers to read the label information on the parcels

Main Features

  • Projection

    Projection of destination pattern


    The projector projects patterns with any design onto the parcel while following it on the conveyor using 3D sensors and cameras to recognize the shape and position.

  • Visualization

    Visualization for work analysis


    Based on the detection and tracking data of parcels, the work volume and logistic information can be displayed on a dashboard. This assists work analysis for improvement of efficiency.



Use Case for Logistics

  • For Logistics

    The staff do not require special knowledge for sorting, so anyone can easily do it. It provides the flexibility to match the number of workers to the parcel volume, for example, to meet seasonal demand.

  • For Manufacturers

    Projecting the order information onto the front of the delivery box enables the staff to check whether the item picked from the shelf is correct for the customer's order when putting it into the box. This can prevent mistakes in the picked items on the spot.
