Features

Flexible configuration

Open Sense is extremely flexible in customization. It’s possible to customize everything from the number of sections in the main menu to the color and the form of the buttons — the variety of configurations is truly enormous and can be tailored to any presentation's needs.

Offline mode

The app works offline in case there is any problem with the external server or the Internet connection. The only thing required is a computer where the app can be installed and managed, so the conference is totally secured from any unexpected crashes and awkward "technical problems" pauses.

Focus feature

The Focus feature allows the audience and the speaker to be literally on the same page. With this function, the admin can redirect all the people in the audience to the same screen so they can, for example, answer a question or take a closer look at the chart on a slide during the presentation.

Translation

Questions in a Q&A section can be automatically translated into the main language of the conference. Open Sense also makes it possible to translate the question into another language as well. For example, when the default conference language is English, the question is asked in German, and the person who wants to understand the question speaks Chinese.

PWA

Progressive Web App, or PWA, is a technology that allows a web app to function as a mobile one. Open Sense can be added as a shortcut to the main screen of the phone. Also, it can be integrated into other apps if it’s necessary.

Challenges and Solutions

The Great Firewall of China

Problem:

Due to political reasons China has very strict rules on domestic Internet regulation. It blocks access to most of the external services provided by foreign companies, like Google or Facebook, that makes it impossible to use any of their products.

Solution:

As Google’s products are not supported in China because of the Great Firewall, we compiled the stack that functions there with a Chinese tool called Baidu for translation. Also, our team created an offline version of the app as well so that there’s no need for any connection to the external server.

Socket connections and statistics processing

Problem:

During the conference, a lot of people had to answer questions in the Surveys section simultaneously. The load size made it hard to calculate the correct statistics of the answers.

Solution:

After the load testing, the team found the bottlenecks and started simplifying the code and configuring the socket connections.

Results

A conference management web app that met our client’s needs. Available worldwide. Already used by the client with amazing audience feedback.
