Assignment 1: Speculative Wearable – Angelina Do (3182746)


The “Emerald of Emotions” is a necklace designed for the dating scene of the 21st century. Dating apps like Tinder, Bumble, Hinger, and Grinder can become exhausting when date-after-date goes wrong. This product allows easy communication between two people to avoid those awkward chats. The “Emerald of Emotions” senses the human heart rate and temperature after a date has been completed. A high heart rate and hot body temperature corresponds with a positive experience, while an average heart rate and average body temperature indicates a missing spark. Instead of having the, “no I would not like to see you again” conversation, it is simply avoided with the glow of LED lights through an elegant emerald.

The emerald has a built-in heart rate monitor and thermometer that is recorded in our corresponding app. The two levels are careful monitored allowing ranges to fit in specific colours. Red means that the individual enjoyed themselves during the date and would like to see their partner again Orange means that the date was just okay and that they could revisit the possibility of a second date. Grey means the date was unpleasant and the individual would not like to see their date again. Our app allows users to turn this necklace on and off via their mobile device, allowing for casual wear as well.


The objective of this jewelry piece is to speed up the process of finding your one true match! Going on second dates with people that you were never compatible with is a waste of time. Your true feelings will be revealed even if you’re too timid to say it with your own words.

This product has a timeless look of a classic diamond necklace, allowing versatility and subtleness of the wearer. The target market is primary users of dating apps or speed-dating (Millennials and Gen Z).

Assignment 1 – Speculative Wearable: Light up Headband


My wearable is a headband that lights up in different patterns according to the sounds around you. It will change to match the sounds around you and create fun patterns of light related to the sounds or music. The product will have three settings, sounds, music and off. These will correlate to the number of times the power button is pressed. The power button is set behind the left ear of the headband so it is out of sight and doesn’t affect the overall view of the headband.

When activated the headband will connect to the user’s phone via Bluetooth and using the microphone of the phone will sense the sounds around the person and adjust the lighting patterns accordingly. If the user clicks the button a second time then the headband will sync the lights to the pattern of the music either being played from the phone or around the user.


The objective behind the creation of this product is to create an accessory that can be fun to wear. It is to create a fun headband that will compliment one’s outfit while it is off as well as help make a statement when the user turns the product on.

Headbands and LED strips already exist so my object is a merge between both the headband and the colourful lights to create something fun to wear. A difference between the lights in the market is that my product can adjust the light-based off sounds that are not just from the music being played.

Assignment 1 – Speculative Wearable: Hedy Fu

My wearable is supposed to be a unisex necklace that monitors your heart rate and flashes colours accordingly, to show bartenders, friends, and wearers themselves that the wearer can no longer drink. This is so that people avoid overdrinking and endangering themselves, as well as making symptoms more evident.

The material of the chain of the necklace will be metal(such as 18k gold/ silver/stainless steel to prevent allergies) and will have a silicone padding at where the node for the pulse detector is. The beads and what reflects the light installed within the necklace chains will be made from glass or plastic.

The necklace isn’t necessarily for all day use since it is meant to prevent overdrinking (although it can be  if the wearer wants to constantly measure their heartbeat). Therefore, like any jewellery, it can get tiring or uncomfortable after being worn for a long time .

It’s inactive state will be the same as when the person is in their usual heartbeat range and will be activated automatically, scaling off of the wearer’s heartbeats. The necklace at its most minimal form, is a singular chain but there are attachable chains of beads to make it into a statement piece. These beads are relatively small for a minimalistic and versatile look, and can be layered for those who wish to wear something more flamboyant. 

Two technologies that are similar and what I drew inspiration from are: 1) Blood pressure monitor (WebMD, 2019).

2) Signal Sending Chip(Reuters, 2018).
