The Qualcomm Snapdragon Digital Pen represents the next generation of the stylus popular with tablet devices. With the size and feel of a regular pen, the Qualcomm Snapdragon Digital Pen gives users control in three dimensions. With it in hand, users can hover over content and click on selected areas to capture and record data.
The tracking orientation of the pen’s position extends approximately 40 centimeters or 1.5 feet from a screen or tablet. This distance-based tracking is designed to accurately measure the coordinates of a nearby object. The pen features a hardware button that users can customize to control their pressure on a tablet, screen or paper surface.
The tablet device uses ultrasound technology to communicate with the digital pen. Two ultrasonic transmitters relay the pen’s position and the axis of rotation, which is picked-up by the integrated microphones in the tablet to triangulate the pen. These capabilities were introduced as part of the Snapdragon 805 chipset. GlobalLogic developed an Android application that illustrates how the Qualcomm Snapdragon Digital Pen can be used to navigate and annotate content.
GlobalLogic collaborated with the Qualcomm Technologies, Inc. (QTI) engineering team from the project’s inception, exploring capabilities that could be integrated into the product design. The entire process was fast-tracked with a goal of demonstrating the product at the Mobile World Congress just four weeks away.
The seamless collaboration between QTI and GlobalLogic’s engineering teams in the Ukraine, San Jose, and San Diego made the accelerated timetable possible. The teams were driven by the concept that exploration leads to innovation and amazing product design solutions.
