#06 • Investigator Timeline | B2B Web-Application
"A web app which helps companies analyses market research about brand perception"
Brief:
For this project, the brief was to create an investigative dashboard for police officers in Denmark. The purpose of the dashboard was to provide officers with a centralized location for accessing all of the information and resources they need to do their jobs effectively.I designed the dashboard with the specific needs and requirements of police officers in mind.

The result was a dashboard that provides officers with quick and easy access to all of the information they need to solve cases and keep communities safe.The dashboard includes a range of features and functionality, including case files, witness statements, suspect information, and more.

It is also fully integrated with other tools and resources that police officers use in their work, making it easy for them to access all of the information they need in one place.Investigative timeline:A timeline is a way to visually represent the events of a case or investigation.

It can be used to help organise information, identify patterns or discrepancies, and understand the sequence of events. A timeline can be created using a variety of tools, including spreadsheet software, graphic design programs, or even a simple pen and paper. Some common elements that may be included on an investigator's timeline include:
• Dates and times of events
• Locations of events
• Names of individuals involved
• Details of any conversations or interactions
• Observations or notes made by the investigator
• Relevant documents or other evidence

Timelines can be especially useful in cases where there are multiple witnesses or suspects, or when there is a large amount of evidence to review. They can help investigators stay organised and ensure that they don't overlook any important details.

Brief:
Designed and built from the ground up, this impact focused organisation, which is mission is to help investigative journalist and researchers more broadly with their daily workflow. and give them new access to income streams from their raw research.

Solution:
Sifter, is an open-source intelligence tool (OSINT) that empowers any investigator to collect, analyse and report their findings visually.

Problem:
Investigations are hard and time-consuming, which makes them very costly. Especially open-source investigations, which by their nature require coding skill sets

Value Proposition:
We radically reduced the time of investigations, by uncovering hidden patterns sooner. Whilst also providing a new crowdsourced income stream

What is it?
We give investigators a simple way to collect and search through sources, and then we have an amazing user experience for analysing their findings
We have built a SAAS product that combines private and publicly sourced data sets, with user-generated notes. which is complemented with a browser extension to directly reference inline statements. All data points are visually collated in a user-friendly node-based graph, from which reports are crafted, and subscribed to by internal or external audiences.

2015 | Object | 🧱 Sound Blocks
An musical instrument that assists learning in how sound fundamentally works
Brief:
What is sound made of? It’s a question that seems simple, but as we all know, the simplest things sometimes hide wonderful complexity. The challenge was taken first to understand what factors and aspects sound is created from. There are a lot factors, too many to be conveyed through language alone, in a short period of time.

So the team created Sound Blocks, which allow people to learn how, with a few parameters, we can create new sounds, and, if desired, imitate real world sounds. It does this by letting the user control the waveform, sound decay, wave length, and volume of three channels, all mixed together. Sound blocks, first and foremost, was created as a tool to experiment with sound, it is playful and engaging. The goal is to help children and people of all ages better understand the basic elements that make up a sound.

How does it work:
You are given three channels to experiment with. You can pick a basic waveform, the duration of the wave, and adjust the volume of each channel. It allows you to understand how synthesisers can emulate real world sounds, such as drums or a keyboard, with simple example recipes to get you started quickly.

The team’s lessons were plentiful. They learned a great deal about what sound is and the factors that make sound and musical sound exist. On the physical computing side, they learnt about circuitry and using resistances to differentiate objects. Each block has its own resistance value and thus can be used to trigger an exact reaction on another software, which in this case is Ableton Live. Coding skills were also required to identify, transform and send the signals into the sound software
Role/s:
• 📦 Prototyping
• ✏️ Product Design (Physical Product)
• 📽 Promotional Video
Process:
Phase 1:
We wanted to create a a device which taught how sound worked, so we broke it down into elements, from those elments we drafted a design for sound blocks

Phase 2
build, we spent a large amount of time laser cutting soldering and hooking up the device to Ableton

Phase 3
Promotion we created a promotional video
Achievements:
• ✏️ Designed, laser cut and assemble the full product
• 🎖Finalist for IXD Awards
