Electronic device with sensors and display devices
An electronic device may have a housing. The housing may be characterized by a vertical axis and may have housing structures such as cylindrical housing structures with a cylindrical surface. A speaker may be mounted in the housing to provide sound through openings in the housing structures. A visual output device may be mounted in the housing to provide light through openings in the housing structures. The visual output device may include an electrophoretic display, a light-emitting diode display, or other display with an array of pixels that display images or may include other components for emitting light. During operation, voice commands may be received by a microphone in the device and action taken based on the commands and other information. The action taken may include playing sound with the speaker and providing visual output with the visual output device.
1. An electronic device, comprising:
a housing;
fabric covering a portion of the housing;
sensors in the housing that determine a location of the housing relative to a user and relative to external objects; and
a visual output device in the housing that emits light through the fabric to display visual information based on the location of the housing, wherein the sensors are configured to determine that portions of the visual output device are unobstructed by the external objects and face the user, and wherein the visual output device is configured to display the visual information on the unobstructed portions of the visual output device that face the user.
2. The electronic device defined in claim 1 wherein the sensors are selected from the group consisting of: echolocation sensors, cameras, proximity sensors, color ambient light sensors, and microphones.
3. The electronic device defined in claim 1 wherein the sensors determine an appearance of the external objects and wherein the visual output device is configured to display the visual information based on the appearance of the external objects.
4. The electronic device defined in claim 3 wherein the visual information comprises an image and wherein the visual output device is configured to display the image in a color that is matched to a color of the external objects.
5. The electronic device defined in claim 3 wherein the visual information comprises text and wherein the visual output device is configured to display the text in a color that is contrasted with a color of the external objects.
6. The electronic device defined in claim 1 further comprising:
a microphone configured to receive a voice command, wherein the visual information comprises an acknowledgement that the microphone has received the voice command.
7. An electronic device configured to be used by a user to control an external device having a display that displays images having a color, the electronic device comprising:
a cylindrical housing;
a fabric having openings that overlaps a portion the cylindrical housing;
a first sensor that determines a location of the cylindrical housing relative to the user;
a second sensor that senses ambient light color changes;
a microphone that receives voice commands from the user; and
a light-emitting device that emits a pattern of light through the openings in the fabric based on the location of the cylindrical housing and the received voice commands, wherein the light-emitting device is configured to emit the pattern of light with a color that matches the color of the images displayed by the external device, and wherein the light-emitting device is configured to automatically adjust the color when the second sensor detects the ambient light color changes.
8. The electronic device defined in claim 7 wherein the light-emitting device emits the pattern of light in a direction that is oriented toward a position of the user in response to receiving the voice commands.
9. The electronic device defined in claim 8 further comprising:
control circuitry that is configured to dynamically adjust a location of the pattern of light on the light-emitting device based on the position of the user.
