Welcome Screen | Pujianto Chiam

Overview

Project Impact

Designed and implemented an intelligent visitor management system that transformed corporate reception areas by creating personalised, multilingual welcome experiences. The system successfully reduced reception bottlenecks whilst enhancing security and visitor experience.

The Challenge

Traditional visitor management systems face several limitations:

Impersonal guest experiences
Language barriers with international visitors
Reception desk bottlenecks
Delayed visitor processing
Security compliance concerns

Innovative Solution

Working as the lead designer, I created a smart welcome screen that:

Recognised registered visitors in real-time
Displayed personalised greetings in preferred languages
Monitored multiple visitors simultaneously
Flagged unauthorised access attempts
Integrated seamlessly with existing security systems

My Role

I contributed across multiple dimensions of the project:

Conceptualisation
Visual Design
Information Architecture
Prototyping on a large HD display (55–60").
Additionally, I worked closely with a junior UX developer to build the Angular app and ensure its seamless integration with the backend system.

Design & Development Process

1. Rapid Conceptualisation (5-Hour Sprint)

Conducted rapid idealisation sessions
Created initial wireframes and user flows
Defined core functionality requirements
Established visual design principles

2. User Interface States Designed distinct screen states for various scenarios:

Idle State: Engaging default screen with branded content
