NFC, touchscreen, sensors, cameras, and gesture recognition for emergency alerts
Given the ‘next gen’ nature of the solution, the service provider was expected to take the idea beyond the “Vision and Scope” statement. Softeq met the selection criteria: an experienced service provider with relevant hardware design and software development skills.
The client was looking for an experienced service provider with relevant hardware design and software development skills to create a curved wrist phone. The initial requirement was to develop a prototype that would demonstrate specific capabilities in an unconventional form-factor: NFC, touchscreen, sensors, cameras, and gesture recognition for emergency alerts.
The client intended to demo the prototype to potential investors to secure funds for the project. Softeq handled the development across several areas — hardware, enclosure, and software.
The smartphone prototype was to have a custom rigid-flex PCB to underlie the curved device shape. Hardware-wise, the prototype was to support the following capabilities:
The team developed a custom app ecosystem to incorporate the demo software so that it met the unconventional screen layout.
The app features a list of songs playable on a tap. The tapped song is displayed as “Playing now” in the list of all songs of this artist.
Business Cards Exchanger
Two phones with the apps installed when placed into proximity would exchange data using NFC. To be able to install the app on the curved phone, the team had to tune up the Android OS at the Hardware Abstraction Layer (HAL). This helped overwrite the default Android behavior – minimizing the running application and requiring users to confirm the steps.
The app is motion and voice recognition enabled. It sends emergency alerts via email to a designated list of contacts. To set up the app, the user teaches it using gestures and voice commands which activate the SOS function.
The team performed RD to assess the available methods, tools, and libraries for implementing the motion and voice recognition capabilities.
Heart Rate Monitor
The app measures current heart rate value (bpm) and displays a chart with real-time beat stats. To measure heart rate, the user needs to press his/her finger to a designated area on the device. To secure measurements precision, the team made some changes to HAL.
Lock and Launch Screens
The software enables the user to unlock the phone with a swipe gesture and shows date and time in the device format. The start screen has a hexagon structure layout and has the following elements:
The team hired a manufacturer in Italy who agreed to design and produce a curved shape enclosure. Given the PoC nature of the device, the enclosure was to provide a hard plastic casing to fit in the rigid-flex PCB and allow mounting on the hand.
As the device is a brand-new smart solution, the company faced the following challenges due to technological limitations:
Once the client secured financial support of investors, they planned to continue the development. The customer aimed to deal with the identified technological roadblocks (e.g. flexi-screen, powerful battery, curved touch panel, etc.) and implement new features (e.g. e-lock, browser, demo game adapted to the curved screen shape, etc.)
