Designing specs for HW requires to understand both User Experience and Technology. I dedicated 1+ year to find the right configuration for components, make sure they were calibrated for an optimal user experience balancing different conditions such as head shape, fingers size, lighting, weather, SKUs, customer needs and expectations. Worked with Firmware establish protocols and reach the granularity for the specs to be code-able.

Have a glimpse into how I work!

After developing ~100 quick prototypes for:

1. Exploring new HW features
2. Designing HW-UX specifications
3. Conducting UXR studies
4. Validating HW components for each factory build,
I achieved a green (Customer Satisfaction Score of 5.5 or higher out of 7.0) on all the HW-UX features I drove for Gen3: Hall Sensor to Power On/Off, LED/ALS on frames, and Buttons force and latency.

After exhausting configurations, the proximity sensor component, however, did not meet the UX bar and the workstream was cancelled.

The UX team was asked to recommend the gesture to trigger the feature. Considering that all the gestures on the frames were already assigned to other actions we knew this addition will imply 2 actions to share the same gesture being one of them by default, and the other one selectable in the Alexa App. We evaluated several options on (1) Reliability of the gesture in terms of accidental triggers (2) Usage of the existing feature (3) Level of education required for existing and new customers (4) Consistency with current gesture mapping mental model.

We narrowed down to two options: (A) Action Button (assigned to trigger Alexa) or (B) Touchpad Long Press (assigned to trigger OS assistant). To gain insights and preferences we ran an A/B UX Research Study for which I built a prototype on a real device.

The recommendation was backed with the following data:
• Audio based active customers in April 2021, 44.5% iOS - 14.6% Android triggered OS Assistant using Touchpad Long Press mostly once, and less than 5 users would use it more than 20 times a month
• Metrics on gestures usage showed Action Button Click (Alexa) is used 3x times than Touchpad Long Press
• Long press is less likely to be recognized as other gestures and be false triggered
• Education for new customers and backwards compatibility for existing customers would be straightforward
• Echo Frames is an Alexa product

To support this theme I first calculated the odds (%) babies from each country have to thrive using the following factors: under-5 mortality rate, stunting rate, mean years of education. Those factors were weighted evenly, and the highest ranked country was colored the brightest green; the lowest, the deepest red.

Then I found this report from UNICEF that contains how many babies are born in each country per day and applied this formula to find out which is the interval in milliseconds between one baby and the next one, for each country.

Finally, I built a hi-res prototype of a world map rank-colored with its odds and thenI added a blinking animation every time a child is born in a country. It is evident that babies are born more often in countries where they will have less odds to thrive.

Team visited Texas where FedEx has existing lockers that are underused/malfunctioning and decided to bring this idea back.

My challenge was to construct 6 App-controlled lockers to be installed and tested during 2 days with 10 participants in Jewel Osco supermarkets around Chicago. Participants could open a locker from an iPhone App by tapping a button on the phone's screen. The App used beacon technology located in different points of the store to authenticate the customer's location and serve as a geo-location guide.

For the HW side of the project, I first built a paper prototype using HTTP Request. The final version used MQTT.

I used WIFI, NodeJS and MongoDB to to monitor the lockers' status remotely.

After the setup was ready, I built and ran a QA automation test 24/7.

It became a worldwide sensation receiving 7M+ visits from all continents, broadcasted on TV programs, emitted on radio stations, published in printed newspapers and posted on more than 6,000 websites.

It was pretty overwhelming being interviewed all of a sudden by BBC India, LBC Lebanon and Middle East International TV, TN Argentina, German Radio Station MDR JUMP, Blu Radio Colombia, Radio Metro Argentina, El Pais Cali Newspaper, Semana Magazine, 20 minutes France, Spain, Switzerland and Mexico, AdvertisingAge, Creativity Online, CNET, Yahoo News, Google News, The Huffington Post Japan, MSN News, Wired, Mashable, The Verge, Gizmodo, BBC, CNN Tech, CNN Latino, DesignTaxi, and so on.

Back in 2005 I co-founded Cuatic, a company specialized in Physical Interaction Installations. In 2008, supported by a €200K investment from risk capital, we created this product flagship product for the firm.

TV network La Sexta opened Hamelin to promote its program The Infernal Wall. Cuatic developed a game that recreated the contest program. The challenge of this game was to go across 10 walls, each one containing a different figure. Players must mimic the figure with their body and fit neatly into the figure of one of the wall, otherwise they lose and start again.

The building is designed by the prestigious studio of Carlos Ferrater and represents the past, present and future of the company. LED light is the protagonist of the façade, which is composed of just one material: glass. The inside, the use of light, audiovisuals, interactive resources and expositive elements entice the visitor to a personal, unique and sensory building experience.

Cuatic actively contributed with the ideation, user experience, coding, animation and construction of the Interactive Tables, Rituals, and the Interactive Catalogue.

Users can walk around a Volvo and see a full 360° X-Ray view, with callouts to the patented World’s first Volvo innovations inside. It was launched at the Geneva Auto Show with huge success, and will be used in other Auto Shows around the world, as well as Volvo dealers.

We developed this project in a crazy time zone difference schedule with the collaboration of 7 different vendors all around the world: App (Munich and San Francisco), 3D model (Munich), 3D animations (Barcelona), Videos (Los Angeles), HTML content (Miami), Music and Sounds (Miami), UX (New York), and on top of the that, the client is in Gothenburg.
