The original brief was about how to enhance the interaction experience with the elements of a bike. it is very complicated and dangerous to interact with digital services while cycling, so why don't upgrade a handlebar for integrating finger gestures. Without changing the hands' position, I could enable a wide range of actions with a smartphone.
The project had a radical pivoting because of COVID limitations of building the product from my room and the project's potential costs.
The new direction was about, inheriting the previously designed interaction, adapting it to a multipurpose controller, and questioning how to break the link between buttons and functions. How to simplify therefore extend the options of piloting a drone, firmly based on an ergonomic experience.
Modular. Compatible with several central modules designed for personalising its function according to what's controlled.
Always ready. The fingers will constantly be in place on top of the sensors to speed up the reaction time.
Custom. The sensors can be linked to different actions depending on the "gestures" done. Also, the user can customise the speed of click (or time between clicks), the level of pressure and the impulse response of the haptic driver.
Including TacHammer™ technology, Fenics has light-fast and accurate feedback to each action performed.
3 dimensions compatible. Integrating the third axis of movement to the thumb opens up new possibilities to interact with elements in a 3D environment.
The 3D controller allows controlling the drone one-handed, what it opens the possibility of moving the gimbal of the camera with the other.
Reaction time is everything. This design allows you saving the time of moving the fingers from one button to the other because they are always in position. The 3rd axis could be linked to adjust crucial variables as sensitivity on real-time.
The rear-side cylindrical texture increases the grip with the palm. Essential to handle it in any position or making different gestures.
The curved side slot is here to create interference at taking the product with the wrong hand, communicating the right position. At the same time, it is a connector to the accessories, powered and attached by magnets.
The front curvature of the product provokes to have the hand more closed at the bottom, so the product rests on it even when the user moves its fingers.
The rear curvature, however, goes along with the thumb to reach its maximum extension and facilitate movement.
The inside rubber thumb pad comes in different sizes to have a perfect fit to different finger dimensions. It also improves the grip to keep the finger in position along with the movement.
when the user tries to trigger the sensor with the ring and little finger sensors separately, those two fingers tend to join each other. The bottom flap is made for creating space between them, therefore improving the mobility experience.
The frontal parenthesis are tactile references to intuitively handling the product.
There is an inside sphere behind each pressure area, creating a space between the rubber layer and the sensor. The squeezable shape improves the response of the sensor and transmits the feelings of activating a mechanism, what becomes intuitive feedback for the user.
Studying handle-bar hacks to bring pro-competition and commuting together.
Some of the most renowned handlebars are stem included, but they are not so likely for commuters
How the ring and the little finger join each other at trying to squeeze individually
Comparison with the previous picture with a shape to separate them.
This project was sponsored by Nanoport with their Tachammer™ technology. A unique haptic driver for a level-up experience.
The first version of prototyping to validate it's shape. The curved slot was impeding the right grip.
First assembly attempt to test tolerances and mechanisms.
The electrical 5v adapter that caused more trouble, providing an unstable voltage.
There is an opportunity simplifying the cable management and devices on the handlebar.
Possible fabric and patterns to improve the actual bar-tapes.
Off-centering the "joystick" enables more movement but become a complicated shape to handle.
First set of prototypes. Red TPU ShoreA 80 printed on fdm.
The design tolerances weren't the right one for the precision of the SLA process.
Wiring 18 cables inside.
Final touches as lubricating the inside dome for having a smooth movement.
Identifying how handlebar and smartphone or on board computer go together.
The designed handlebars before latticing in parametric software. The production cost would be £8000 using metal additive manufacturing. This is why the project had to evolve.
It was incredibly hard to find and 3D model the right texture for the backside of the product.
The new watershed 3D printing came with a wonderful detail and finish.
Unfortunately SLA resolution and finishes quality was poor.
Last-minute modifications for having accessible connectors for future modifications.
Small hand - Hand length: 16cm. Hand breadth: 7.5cm.
