Abstract
A device comprising a magnetic stylus, touch sensor, and reflective display provides new opportunities for content presentation and interaction. A user interface is configured to use input from the stylus and touch sensor to modify content presented on the reflective display.
Claims30
A device comprising:
- a processor;
- memory coupled to the processor;
- one or more magnetometers disposed about the device and coupled to the processor;
- a magnetic stylus configured with a magnetic field detectable to the one or more magnetometers;
- a touch sensor coupled to the processor;
- a reflective display coupled to the processor;
- an application module stored in the memory and executable by the processor to:
- present a writing lesson on the reflective display, the writing lesson instructing a user to use the magnetic stylus to write on the reflective display;
- detect, via the touch sensor and the one or more magnetometers, user input on the reflective display;
- performing an analysis of the user input based at least in part upon motion data received from the touch sensor and the one or more magnetometers, wherein the motion data includes a stylus angle, a stylus velocity, a stylus pressure, and an angular bearing of the magnetic stylus;
- and
- present feedback pertaining to the writing lesson on the reflective display based at least in part on the analysis.

A device comprising:
- a processor;
- memory coupled to the processor;
- one or more magnetometers disposed about the device and coupled to the processor;
- a magnetic stylus configured with a magnetic field detectable to the one or more magnetometers;
- a touch sensor that is coupled to the processor;
- a reflective display coupled to the processor;
- an application module stored in the memory and executable by the processor to:
- receive signature data generated by movement of the magnetic stylus, the signature data received from the touch sensor and the one or more magnetometers;
- generate, based at least partly on the signature data, a signature profile comprising a stylus angle, a stylus velocity, a stylus pressure, and an angular bearing of the magnetic stylus;
- compare the signature profile with a previously stored signature profile associated with a user;
- and
- identify the user based at least in part on determining that the signature profile is within a pre-determined tolerance of the previously stored signature profile.
9 more elements
One or more non-transitory computer-readable storage media to store instructions that are executable by one or more processors to perform acts comprising:
- presenting a writing lesson on a reflective display of an electronic book (eBook) reader device, the writing lesson instructing a user to use a magnetic stylus to write on the reflective display;
- detecting, from both a touch sensor of the eBook reader device and a plurality of magnetometers disposed around the eBook reader device to detect manipulation of a magnetic field generated by the magnetic stylus, user input on the reflective display;
- determining an orientation of the magnetic stylus;
- adjusting the user input based at least in part of the orientation of the magnetic stylus;
- performing, based at least in part upon motion data received from the touch sensor and the plurality of magnetometers, an analysis of the user input to determine that the writing lesson was performed correctly, wherein the motion data includes a stylus angle, a stylus velocity, a stylus pressure, and an angular bearing of the magnetic stylus;
- and
- displaying, on the reflective display, an indication that the writing lesson was performed correctly.
4 more elements
A method performed by one or more processors that are configured with instructions to perform acts comprising:
- presenting a writing lesson on a reflective electrophoretic display of an electronic book (eBook) reader device, the writing lesson instructing a user to use a stylus to write on the reflective electrophoretic display;
- receiving user input from one or more magnetometers disposed around the eBook reader device, wherein the one or more magnetometers detect manipulation of a magnetic field generated by a magnetic stylus on the reflective electrophoretic display;
- determining an orientation of the magnetic stylus;
- adjusting the user input based at least in part of the orientation of the magnetic stylus;
- determining that the writing lesson was performed correctly based at least in part on motion data received from a touch sensor of the eBook reader device and from the one or more magnetometers, wherein the motion data includes a stylus angle, a stylus velocity, a stylus pressure, and an angular bearing of the magnetic stylus;
- and
- displaying, on the reflective electrophoretic display, an indication that the writing lesson was performed correctly.
