Using spatial information with device interaction

Номер: US20150019162A1
Автор: Allen Ming-kuang Han, SR., Dennis Hodge
Принадлежит: Amazon Technologies Inc

The amount of resources needed for an electronic device to track and/or interact with a user is reduced by utilizing a predicted relative position of that user. In some embodiments, a full 360° scan is performed using at least one image capture element to locate a primary direction to a user of the device. Once this direction is determined, a smaller range (e.g., 45°) centered around that direction can be used to capture, analyze, or provide information for the user. As the user moves, the determined direction is updated and the range adjusted accordingly. If the user moves outside the range, the device can increase the size of the range until the user is located, and the range can again be decreased around the determined direction. Such approaches limit the amount of image or audio information that must be captured and/or analyzed to track the relative position of a user.

A circuit board and four photocells are installed at the bottom of a cassette. Each photocell is connected to fine positioning fibers located in the same direction as the photocell, and is connected to coarse positioning fibers located in a direction diagonal to the direction of the photocell. By using a daylighting method of combining fine-positioning daylighting and coarse-positioning daylighting, the number of the photocells is reduced, the design of the circuit board is simplified, and costs are reduced; moreover, because the coarse-positioning daylighting module can collect sunlight in a wide-angle range, the tracking angle range of the sensor is enlarged.

In one embodiment, the method may include receiving first data corresponding to a hinge angle (θ) measured between a first surface and a second surface of the IHS, receiving second data corresponding to a user's gaze on the first surface or the second surface, and using the first data and the second data to provide accurate eye tracking data when the user's gaze is directed to the second surface. When the user's gaze is directed to the first surface, the method may use the second data, but not the first data, to provide accurate eye tracking data. 1. A method to improve the accuracy of eye tracking data generated by an eye tracking system coupled to a first surface of an information handling system (IHS) , wherein the first surface of the IHS is coupled to a second surface of the IHS via a hinge that enables the first and second surfaces to rotate about an axis over a range of hinge angles , and wherein the method comprises:receiving first data corresponding to a hinge angle measured between the first surface and the second surface of the IHS;receiving second data corresponding to a user's gaze on the first surface or the second surface; andusing the first data and the second data to provide accurate eye tracking data when the user's gaze is directed to the second surface of the IHS.2. The method as recited in claim 1 , wherein the first surface is parallel to a gaze interaction plane (P) of the eye tracking system claim 1 , and wherein the second surface is displaced from the gaze interaction plane (P) by the hinge angle.3. The method as recited in claim 1 , further comprising using the second data claim 1 , but not the first data claim 1 , to provide accurate eye ...

A system for cross verification of data captured by a consumer electronic device is disclosed. Primary data, for example, a photograph, is captured by a mobile capture device, and metadata including the time and location of the capture is associated with the primary data. Environmental data, for example, pressure, temperature, visible WiFi networks, visible cell towers, is also measure by the mobile capture device. Other capture devices are identified in the vicinity and those other devices also measure environmental data. The measurements of environmental data can then be compared in order to calculate a confidence level in the position metadata associated with the primary data. 1. A system for attributing a confidence level to time and location metadata associated with primary data , the system including a plurality of mobile capture devices and a mobile data communication network allowing data transfer between the mobile capture devices ,each mobile capture device including at least one sensor for capturing primary data, and being adapted to provide metadata specifying at least the time and location relating to captured primary data, and each mobile capture device further including at least one further sensor for measuring at least one environmental parameter, capturing primary data using the at least one sensor;', 'associating metadata with the primary data, the metadata specifying at least the time and location of the capture; and', 'measuring and storing at least one environmental parameter at the time and location of the capture, and associating the measured environmental parameter with the primary data,, 'each mobile capture device being adapted to carry out the steps ofin response to a trigger, measuring and storing at least one environmental parameter; and', 'transmitting the measured environmental parameter on the communication network,, 'and each mobile capture device being adapted to carry out the steps ofin response to a remote command,and the system ...

Locations of a person's hand, shoulder and hip in three-dimensional space are received from a three-dimensional position sensing device. A shortest distance from the location of the person's hand to a line between the location of the person's shoulder and the location of the person's hip is determined. The shortest distance is compared to a threshold to determine if the person is overreaching. When it is determined that the person is overreaching, a user interface is provided to indicate that the person was overreaching. Additional location information for points on the person's body are used to determine if the person is performing a high lift, a low reach or a twist. 1. A method comprising:receiving locations of a person's hand, shoulder and hip in three-dimensional space from a three-dimensional position sensing device;determining a shortest distance from the location of the person's hand to a line between the location of the person's shoulder and the location of the person's hip;comparing the shortest distance to a threshold to determine if the person is overreaching;when it is determined that the person is overreaching, providing a user interface to indicate that the person was overreaching.2. The method of further comprising:receiving the location of two points on the person's body from the three-dimensional position sensing device;determining a distance between the two points; andsetting the threshold based on the distance between the two points.3. The method of wherein one of the two points is the person's wrist and another of the two points is the person's elbow.4. The method of wherein the threshold is set to about one hundred fifty percent of the distance between the person's wrist and the person's elbow.5. The method of further comprising:determining an angle between a line from the location of the person's hand to the location of the person's shoulder and a line from the location of the person's shoulder to the location of the person's hip;comparing the ...
