- Challenge

Design a novel interactive wearable device for citizens to interact with a smart city to enable a sustainable future.

- The Problem

Construction workers face persistent challenges related to inefficiency and safety

Studies and industry reports have found that construction projects often experience delays and cost overruns due to inefficiencies in resource allocation, poor planning, and inadequate communication between project stakeholders. The industry also accounts for a significant number of workplace accidents and fatalities compared to other sectors, which are mostly caused by inadequate training, insufficient safety protocols, and a lack of awareness.


How might we help construction workers improve their working efficiency and safety on construction sites in the city of Melbourne?

- Solution

A prototype designed with several plug-ins to address the safety and efficiency issues in the construction industry.

Third Eye
Trusty Beam
AR Visor

- Process

Ideation Phase

Before coming up with the idea of a helmet, we came up with other different wearable devices such as a glove and an AR Glass. Reflecting on all our ideas, we decided a smart helmet would be the most suitable in regards to construction workers:

  • Reduces the learnability of introducing a "new" wearable device as the WorkMaster will essentially be replacing their existing safety helmets.
  • More suited for projecting straight lines and 3D images as compared to the gloves and glasses designs.
  • The helmet could be more effective in preventing head damage.

A) Safety

1. Electroencephalogram
EEG is utilized to provide real-time physiological data to ensure our users are working under healthy physical conditions.

2. Safety Evaluation & Construction Analysis
Through the use of Third Eye and a smart city database, WorkMaster can evaluate if users are working in a safe environment, such as scanning the structure and upload to the central network to evaluate the safety of it.

3. Air Quality Monitoring
Monitor real-time air quality levels using sensors & databases and warn users when chemicals have reached a certain level.

B) Efficiency

1. Instructions for hazardous work
Using Trusty Beam to shoot laser guidelines for the workers when operating machines.

2. Real-time weather forecasting
Real-time notifications to the workers for weather events such as raining, snowing, etc, helping the workers to plan their working schedule proactively for the sudden weather event.

3. Resource sharing
Each company connects to a central database that stores information about the availability and corresponding locations of their building materials, through accessing the database, facilitate the workers gain access to the materials easily.

4. Schedule updates
The information on the working schedule stores in the central database. WorkMaster will update the construction worker instantly with the information of the latest working schedule whenever there is a change or modification.

- Outcome

  • Increased communication between workers.
  • Incorporated safety features to protect worker welfare.
  • Eliminates the need to carry additional tools like a measuring tape or ruler.
  • Update the worker with the real-time information.

- Limitations

  • Requires internet connection.
  • Heavy weight with the AR system and plug-ins.
  • The plug-ins could be damaged on the construction site.
  • The learning curve for construction workers could potentially be challenging since it is a smart helmet.

- Other Applications

  • Potential pairing with smart clothing for more comprehensive features of WorkMaster.
  • Create an offline mode so it still can provide limited uses in the case of connection losses.
  • Creation of additional plug-ins could be explored to accommodate for other pain points that construction workers or any other outdoor workers face.

- Key Takeaways

  • Great amount of user research has to be done. For a product specially designed for particular users, a detailed user research should be done to tailor their needs to tackle the problems that they are facing.
