PROBLEM OVERVIEW

PROJECT IMPLEMENTATION

PRODUCT ACHIEVEMENT

PROBLEM DESCRIPTIONAs healthcare complexes like Tan Tock Seng Hospital become increasingly more sophisticated, it becomes harder for staff members and visitors to be familiar with the area, resulting in navigation problems.

The project aims to explore and develop new means to resolve this current issue of wayfinding.

OBJECTIVE

01 02 03

01 02 03

Partner with TTSH to explore new alternative solutions

Provide an enjoyable user experience for visitors

Utilizes on healthcare services or for visitation purposes

01

02

Design and build a navigation system for visitors and staff to use within Tan Tock Seng Hospital.

Catered for elderly and disabled people

Step-to-step visual aid

Improve the visitors’ experience by taking into account the needs of both Tan Tock Seng Hospital and the visitors.Special considerations made:

STEP1: STAKEHOLDER ENGAGEMENT (SE)

SE

VISITORS

NUS

TAN TOCK SENG

1] Introduced to the Virtual NUS (VNUS) team to understand and learn how they build the new NUS Map application.

1] Consulted friends and family members who have been to the hospital to understand their current pain-points2] The team also made visits to experience navigating around the hospital.

1] Held meetings with the staff of TTSH to agree on the expectations, main pain points of staff and resources or help given to the team2] Gathered on the limitations of operating certain devices within the hospital.

Based on this SE framework, we were able to narrow down on the scope of the project based on the expectations of the different stakeholders and tap on existing technologies from VNUS to build on our finalised solution. (Communication Skills)

STEP2: LANDSCAPE ANALYSIS

Concierge Counters

Navigation Machine Maps

& Signs

SearchOnline

Require the memorisation of the detailed routeLimited to the staff’s availability and language abilities

Require the memorisation of the detailed routeNot user-friendly, as it requires strength to maneuver around

Outdated and not detailed enough

Confusing to visitors as some have too little or too much informationToo small which may not be visible to elderly

Conducting a landscape analysis on the current 4 solutions allow us to have a better understanding of their limitations in resolving the navigation problem.

STEP3: COST BENEFIT ANALYSIS STEP4: MARKET EVALUATION

Evaluating of market leaders of navigation application allow us to understand and learn the best practices to incorporate into our project.

Connexient’s turn-by-turn indoor

Jibestream’s multiple language

Cisco’s directional arrow

22 Miles Wayfinding’sinteractive Point-of-Interest Map

Google Maps’s smooth user interface

Assessing each possible solutions based on their potential costs and benefit allowed us to conclude that building a mobile application would yield us the best results.

STEP5: BUILDING OF MOBILE APPLICATION

Mobile App Design Building of Mobile App

User-testing & Implementation

Arcgis IndoorAtlas

Software: Android Platform Other Softwares

Designing of the mobile application involves breaking down the desired features into bite-size deliverables so as to build a logical workflow and better understand how features relate to each other.

Eg. Plan for the design of the Point-to-point navigation

Based on the logical workflow, we have to visualise the user interface of each individual feature and build it subsequently.

Live testing with various stakeholders to gather feedback for the usability of the mobile application further. These feedbacks will be taken into consideration for the improvement of the mobile application.

Examples of improvements from user-testing

Step 1: Digitalisation of Autocad file of TTSH

Step 2: Building of the network (Path walkable)

Step 1: Installation of Beacons within TTSH

Step 2: Footprinting of the routes in TTSH

Arcgis is a geographic information system that is used for creating map layers as well as the compiling and analyzing geographic data.

Map on ArcgisAutocad File

This path that is identified in Arcgis is the most optimised path available.

IndoorAtlas integrates the sensors within smart devices by picking up data sources (magnetic, bluetooth, wifi) to indicate the user’s precise location.

Green: Strong strength in magnetic coverage

Yellow: Moderate strength in magnetic coverage

Physical Installation

Eg. Route from Diagnostic Radiology to Clinic B1b
