EmotivPRO Mobile: From blank canvas to MVP release in 3 month.

Principle Designer * Product Owner * Lead Researcher

Objective

Transition the desktop-oriented EEG data collection tool to a mobile platform, overcoming challenges in feature prioritisation, user experience design, and strategic alignment. The project focused on designing an intuitive user interface that optimised mobile usability while maintaining core functionality and alignment with business objectives. Core KPI to maximise mobile adaptation, aiming for 50% user base in M3.

Problem
Statement

With the absence of quantitative research and analytics within the desktop app, identifying essential features for mobile adaptation and understanding user behaviour becomes inherently difficult. Additionally, the spatial limitations of mobile screens necessitate careful consideration in selecting and presenting data streams and interface elements.

Methodology

Surveys

To understand user needs, we developed a survey that explored feature usage, desired functionalities, and app use cases. This yielded valuable quantitative and qualitative data.

In collaboration with marketing, we launched an email campaign targeting previous mobile solution inquiries. While the initial email had low response (2), a follow-up campaign offering a store discount incentive significantly increased participation, gathering over 50 responses in a day.

Interviews

We conducted in-depth interviews with EEG data collection professionals to understand their workflow, needs, and expectations. This qualitative research revealed valuable insights into their perceived strengths and weaknesses of mobile research applications. Notably, video capture and touch-based controls for marking events during and after recording emerged as highly desired features.

Contextual inquiry

We observing professionals in their natural environment as they performed EEG data collection tasks to understand the context of use, workflow challenges. This research informed spatial design decisions and helped us optimise the presentation of data streams and interface elements.

User tests

By making low fidelity prototypes we quickly tested our ideas with the professional EEG researchers internally to help us validate concepts that worked and also tested those that passed initial filters with engineers to check for feasibility of development.

Solution development

Surveys helped us prioritise features for the Minimum Viable Product (MVP), focusing on three key data streams and essential device status displays.

We introduced "Experiment Templates" to let users save and customise experiment settings, tailoring the data view and controls to their preferences. This democratises advanced research on mobile.

We planned features like experiment building and video recording for future releases, ensuring the app's scalability and competitiveness with desktop solutions.

User testing confirmed the effectiveness of on-screen controls and explored options for remote event triggering with USB/Bluetooth hardware.

Taking a lean approach, we reduced the initial scope (from 18 epics/100+ user stories) to focus on 6 epics/28 user stories for the MVP. This streamlined development with close to 200 UI screens. Early integration of QT analytics with over 100 event tracks ensured valuable user data collection from the start.

Outcome

In prioritising innovation for Emotiv PRO Mobile, we placed user-centred design at the forefront. Extensive research through surveys, interviews, and user observations provided valuable insights. User feedback analysis revealed video capture and touch-based event marking as top priorities, which were then validated through low-fidelity prototypes.

This resulted in a refined interface for the MVP featuring separate control and device panels, alongside customisable Experiment templates. Strategically, the MVP was designed for future expansion with integrated QT analytics, all within a tight three-month deadline.
