Abstract
Methods, devices, and systems are described for bumping a mobile device, such as a smart phone, against a fixed poster board display at a store to initiate a download of coupons, advertisements, or other benefits to the mobile device. Products can be rated by a user's up/down bump or other bump patterns. Using accelerometer-based inertial measurements, multiple users can control multiple mouse cursors on a large display with their mobile devices in order to select information to be downloaded to their mobile devices. The multiple users can bump the display in order to select their items simultaneously.
Claims19
A method comprising:
- receiving a first pointer location on a fixed display from a first mobile device;
- receiving a second pointer location on the fixed display from a second mobile device;
- displaying simultaneously a first cursor at the first pointer location and a second cursor at the second pointer location;
- receiving a selection indicator from the first mobile device indicating a bump sensed by an accelerometer coupled to the first mobile device;
- and
- recording a selection based on the selection indicator and the first pointer location,
- thereby allowing future analysis of a user's selection on the fixed display.
A method comprising:
- calibrating a position and orientation of a mobile device with respect to a fixed display using a bump between the mobile device and fixed display;
- determining a direction with respect to the fixed display at which the mobile device points;
- sending the direction to the fixed display;
- sending a selection indicator to the fixed display, the selection indicator indicating a bump sensed by an accelerometer coupled to the mobile device;
- and
- receiving information from the display in response to the sending of the selection indicator.
A shared-cursor display apparatus simultaneously controllable by multiple mobile devices, the apparatus comprising:
- a fixed display;
- a receiver configured to receive position data, orientation data, and selection indicators from multiple mobile devices, each selection indicator indicating a bump sensed by an accelerometer coupled to the respective mobile device;
- and
- a processor coupled with the receiver and display, the processor configured to determine from the position and orientation data a first pointer location corresponding to a first mobile device and a second pointer location corresponding to a second mobile device on the fixed display,
- wherein the display is configured to simultaneously display a first cursor at the first pointer location and a second cursor at the second pointer location.
