VES – Exhibition Application

The client, a large-scale event management company based in Ho Chi Minh City, desires to have all participants in its events fully supported. This is very important in cases where there is a huge quantity of booths, displayed products, information related to workshops and side activities and participants in the events complained that they often get lost in nearly 500 booths at the exhibition. Businesses who own booths also need to advertise their products to the participants and do not want any participant to gain insufficient information about them.


The following criteria should be met:

  1. Participants:
    1. Ability to gain information about the booths, products, workshops and side activities.
    2. An app to serve as a map for participants in the event.
    3. A reminder of interest events or workshops.
  2. Booth-owning businesses.
    1. Information of each business and product should be looked up easily.
    2. A bridge to help users quickly contact the business.
  3. Project owner:
    1. Minimization of costs for support.
    2. Increase of the credibility of customers and businesses when their needs are met. This results in long-term benefits for the project owner.


To satisfy all stakeholders, the solution used to be proposed was to distribute the list of the booths, place many signboards, and arrange more guides. However, cost is a problem as exhibitions have more and more booths. That makes this solution very difficult to work with low costs. Moreover, over time, the total amount of money spent by the project owner may be many times bigger than the choice of a technology option.

Therefore, a smart mobile app is the optimum solution, as a smart app can address all of the above problems.


Import of a large amount of data:

The first problem when the team received the project was the amount of information that needs to be entered immediately before each event. All data was available only one week before the exhibition. The contents should be accurate and the image quality should be optimized to the extent allowed without affecting the data loading performance.

Mapping process:

Loading of each node based on smart algorithms required the completion of import of all data of the booths before introducing them to the node system. This process was used to be done completely manually by the team by adding the nodes onto the map one by one and this usually took about 1 week to complete.

Project delivery time:

It took about 1 month from the first delivery of information from the client to the date of the first release version. All phases should be complete: design (wireframe, mockup), development and release of the product and data import for the latest events.

Overcome difficulties:

  1. Automation of the entire input process:

The team completed the data import system with high data density for a short time for the data to be processed and the images to be optimized before imported completely automatically into the database.

  1. A separate app for mapping:

Inputting nodes is a very difficult job and requires a lot of time. We set up a team to build a mapping tool to help put nodes into the data quickly and accurately with a user-friendly interface.


By reducing the human resource for the above-mention works (beyond the contents contracted with the project owner), we could not only imported the data accurately but also save time – down to 80% of the time compared to before. This provided great benefits for the project owner and for ourselves.



With the latest card design philosophy, we want to aim for a product that is both convenient and modern.




The final product is made after the combination of colors and detailed inside design.



This is a very challenging project in terms of technology and time but we finally finished the project thanks to the efforts of the entire team.
