HAND-HELD DEVICE WITH TOUCHSCREEN AND DIGITAL TACTILE PIXELS

Abstract

A hand-held electronic device is disclosed. The device may comprise a
case case having one or more major surfaces; a touch screen disposed
on one of the major surfaces, the touch screen; a processor operably
coupled to the touch screen; and one or more tactile pixels disposed
proximate the touch screen. Each of the tactile pixels includes an
actuatable portion coupled to an actuator and a sensor. The actuator
and sensor are coupled to the processor. The actuator is configured to
actuate in response to instructions from the processor and the sensor
is configured to generate signals as inputs to one or more programs
executed by the processor when pressure is applied to the actuatable
portion. The actuatable portion is actuatable by the actuator between
first and second positions. A tactile feel of the actuatable portion
is different in the first and second positions.

DATA TRANSFER USING HAND-HELD DEVICE

Abstract

A hand-held electronic device and file transfer method are disclosed.
The device may comprise a case, a processor and a memory. A case
motion sensor and a remote device detector may be coupled to the
processor. A communication interface may be coupled to the memory and
processor. The processor may be programmed with instructions that,
when executed cause the device to recognize a remote device, recognize
a gesture from resulting from motion of the case, and transfer a file
from the hand-held device to the remote device or vice versa in
response to recognition of the gesture. Alternatively, the
instructions may cause the device to identify a file to be transferred
from a source to a destination, identify the source and/or
destination, recognize a gesture resulting from motion of the case,
and transfer the file from the source to the destination in response
to recognition of the gesture.
