Under the Guidance of Kevin Chiam
A foot attachment that clips onto a hikers’ shoe, with replaceable pods that holds fertiliser solutions for trail marking
Haptic feedback when activating & deactivating the device, and when the device needs attention
Haptic feedbacks are sent in the form of vibrations when the device needs attentions. Such situations include when the battery level is low & when solution level is low.
Dispenser is designed to dispense trail marker every 2.5 metres
We tested 2.5m to be minimum distance to ensure the back tracking trail's visibility to hikers. The quinine in the solution is fluorescent under UV light, This also allows hikers to see the solution at night.
Paired with companion app that utilises locational data collected from the phone’s GPS to plot off-trail hiking journeys
In case of emergencies or rain where blue markers disappears, hikers will be able to rely on this app to find the nearest safe trail used by other hikers. The App also provide the option to share their off-trail hiking route, gathering crow sourced data to inform decision making, before and after a hiking trip.
Applying the magic principal of "Vanish" to the design of everyday interactions
Magic operates at the delicate intersection of art, science, engineering and design. In fact, magician are very similar to designers; both professional strive to create unforgettable moments for their audience.
Given the magic principal of Vanish - Defined as an object disappear as if by "magic". Our team approach the project through a series of hypothesis driven experiments to identify design opportunities within the magic principal of "Vanish"
Synonyms of vanish were generated to further define the context of application
We explored different definitions of “vanish" (Diminish, Evaporate, Fade, Depart). Through plotting relevant keywords around these synonyms we were able to generate a few possible scenarios where the application vanish could enhance the process.
We were intrigue by the idea of using vanish to improve clarity in way finding
We conducted experiments to verify our hypothesis : Minimising information enhances clarity of route in way finding
To reduce the amount of visual information, we physicalised the route element into tangible objects like a string, pebble milestones for participants to follow.
Users felt guided by a physical route and navigating was straightforward.
Direct guidance from physicalisation reduced the need for users to mentally visualise directions to their surroundings.
Reducing reliance on digital device in way finding by translating visual guidance to sound, haptics and temporal trails back tracking trails
The route provided participants with constant visual reference to their previous route.
A vanishing route can still provide constant affirmation that users are on the right route
Mapping intuitive user interactions to form iterations
Interviews were conducted to discover the most intuitive way for the user to activate a device on their foot. We recorded the first interaction performed by the user under the scenario and use that to design the mechanism and form of our product.
Participants asked to activate “something” on their shoe while walking.
Participants tend to perform actions that they were familiar with (stomping or sliding).
Stomping were comfortable yet distinct enough to signal an activation of a device
Design through experimentation
Understanding user insights behind observations
Preparation is key
