ADAA Semifinalist

Taptrac is a modular smart wearable concept which helps you keep track of your group members at any public events like festivals, music concerts, clubs, corporate conferences, exhibitions, trade fairs, religious places, zoos, amusement parks, sport stadiums, etc. Special considerations has been made in its design to have minimal user interactions, make it very immersive, superficial, inclusive and easily create value for the users with an emphasis on universal design thinking principles.

Design Brief



Design a wearable for the people visiting huge social and public events where they travel in groups and often tend to lose track of their group members, which also acts as a customer tracking system for the event organizers helping them in better event planning, thus creating a larger overall value.


Taptrac Persona 1
Persona 1 - The Consumer


The group of people who attend social and public gatherings such as music festivals, sporting events, rock concerts, exhibitions, conferences, theme parks, etc.

They want to keep track of their group members without moving out of their immediate environments at all time at the event.
Persona 2 - The Planner


Organizes events such as music festivals, sporting events, rock concerts, exhibitions, conferences, theme parks, etc.

They need a better way to track people in real time, and have live data to help support the logistics of running the events efficiently with huge crowds.

Design Considerations



Minimal user interactions.

Caters to varied user types and event types.

Should be very immersive and superficial.

Easily creates more value for the attendees

Ideate
Concepts, Structuring & Refinement

The idea was to design a wearable, irrespective of gender or the garments worn by that person. Naturally, anything to be worn on the hind side of the body or below the chest or shoulders or head or face were cancelled out.

Also, the intention was to design a modular wearable which could fit into any wearable for any event ambience. The module is to be used by the event organizers as a Proof of Entry & Exit and they can fit it to a smart band or a smart badge or a smart pendant or a smart jewellery bracelet, etc. as per the public event.

Modular Wearable


Taptrac Concept 1
1. Cartesian Coordinate System


Taptrac Concept Tick Helps user locate their group members.
Taptrac Concept Tick Familiar interface, resembles google maps.
Taptrac Concept Cross Requires a large Hi-Res display screen.
Taptrac Concept Cross Demands precise mapping of the entire event location on the screen.
Taptrac Concept Cross For larger event spaces, difficult to place group members as small dots.
Taptrac Concept Cross High cognitive load as one cannot understand the distance of the members.
2. Radar Coordinate System


Helps user locate their group members. Taptrac Concept Tick
Simple interface with a centrally fixed location and dots to represent group members. Taptrac Concept Tick

Taptrac Concept 3
3. Simplified Radar System


Taptrac Concept Tick Helps user locate their group members.
Taptrac Concept Tick Simpler interface with a centrally fixed location and dots only at the rim of the dial.
Taptrac Concept Tick LEDs placed along the rim removes the need of a Hi-Res screen.
Taptrac Concept Cross Doesn’t require exact mapping but lack of relative positioning complicates the system.
Taptrac Concept Tick For larger event spaces, members are represented as clusters and not individually.
Taptrac Concept Cross Distance of members cannot be calculated.
4. Relative Radar System


Helps user locate their group members. Taptrac Concept Tick
The interface is simple & minimal but too many colours create a high cognitive load. Taptrac Concept Cross
LEDs placed along the rim removes the need of a Hi-Res screen. Taptrac Concept Tick
Maximum distance is always set to the farthest member irrespective of event area size. Taptrac Concept Tick
For larger event spaces, members are represented as clusters and not individually. Taptrac Concept Tick
Distance of members can be understood from the interface. Taptrac Concept Tick

Colour Blindness
Taptrac Part-19

[Above] Selected range of colours to display the relative distance of a member from the user.


However, such wide range of colours create problems for those with color deficiencies as they are often difficult or impossible for them to perceive. Hence it was crucial to take color-blindness into account because a considerable percentage of our population is colour blind and it not only helps color blind people, but also aids understanding by normally sighted people. Converting our selected range of colours in total and partial colour blind scale, showed the following possible colour discrepancies:

Taptrac Concept Cross The interface is simple & minimal but too many colours create a high cognitive load.

Taptrac Concept Tick LEDs placed along the rim removes the need of a Hi-Res screen.

Taptrac Concept Tick Maximum distance is always set to the farthest member irrespective of event area size.

Taptrac Concept Tick For larger event spaces, members are represented as clusters and not individually.

Taptrac Concept Cross Distance of members can be understood from the interface but isn’t a very inclusive design.

Taptrac Concept 5
5. Relative Radar & Monochrome Bars


Taptrac Concept Tick Helps user locate their group members.
Taptrac Concept Tick The interface is simple, minimal and, being monochromatic, is calm and consistent.
Taptrac Concept Tick Thin monochromatic LED bars represent position and distance together. No screens required.
Taptrac Concept Tick Maximum distance is always set to the farthest member irrespective of event area size.
Taptrac Concept Tick For larger event spaces, members are represented as clusters and not individually.
Taptrac Concept Tick Distance of members can be easily understood from the UI and is dynamic.


The refined concept of relative radar and monochrome bars eventually solved most of our design requirements and was also well aligned to our idea of making it simple and catering to a wide range of users and event types.

Competitive Analysis
Value Proposition, Future Scope, Target Markets

Taptrac Persona 1
Value Proposition

Attendees

Keep track of their group members with a single tap.

Specific to a type of event and need not buy it as a personal asset.

Need not compromise with their look and attire. Different wearables at different events.
Value Proposition

Event Organizers

Keep track of all attendees at their event.

Real time crowd density data.

Monitor and accordingly manage and plan their services better and efficiently.

Control intensive situations like crowd congestions, emergencies, etc. at the earliest.

Improve market competencies by studying crowd flows at different events and locations.
Taptrac Persona 2
Future Scope


Future-1

The device can itself be treated as an Event Ticket/Pass and send across to the user.

Future-2

Built in NFC Chips can be used for digital payments at various refreshment counters.

Future-3

A personalized device can help you connect with new people at the event and even afterwards.

Future-4

Study and analyze event data and improve market competencies for different event organizers.
