ASSUMPTIONS + RESEARCH

i began with some assumptions and personal experiences to understand any biases. while learning about my own experiences, i wanted to explore what kind of questions i'm asking and what kind of answers i seek when converting time zones.

figjam––understanding assumptions (purple), relevant research questions (yellow), and natural interaction patterns (white)

to understand how other's perceive this process, i worked with 5 participants during a co-design workshop. here, i focused on the frequency, reasons, and thoughts when converting time zones. for 3 scenarios, participants would mentally walk me through their process of converting time zones and for the other 3, they would actually perform the task. in between these, they were also probed to visualise a diagram of what they think when converting time zones (right).

time zone conversion visualisations from co-design participants

interestingly, participants were visualising time zones on a scale. passage of time was like a flow to them. most participants were thinking in contexts of day vs. night.

Humans think in context––the context of calling my parents at off hours, the context of prioritising a client's work hours.

CURRENT SYSTEMS

simultaneously, i was auditing current systems.

enterprise systems like outlook are for paid teams, require technical load, and do not work for ICs.

platforms like lettucemeet/doodle are slow, labour intensive, and require negotiation.

TYME SOLVES FOR THIS

tyme is an iOS application, built using SwiftUI. it stays on your phone, so you can convert times on the go. it's meant for families that are scattered across time zones. it's for teams that work remotely and make decisions on every call. it for anyone who wants to save time.
