Abstract

A wearable electronic device comprises a sensor providing a sensor signal, which sensor is one of a temperature sensor and a humidity sensor. A control unit determines, subject to at least the sensor signal, if the wearable electronic device is worn by a user, and provides an output signal indicative of a result of the determination.

Wearable electronic device

Abstract

          A wearable electronic device comprises a sensor
providing a sensor signal, which sensor is one of a tempera-
ture sensor and a humidity sensor. A control unit determines,
subject to at least the sensor signal, if the wearable elec-
tronic device is worn by a user, and provides an output signal
indicative of a result of the determination.

Technical Field

          The present invention relates to a wearable elec-
tronic device, and to a method for determining if a wearable
electronic device is worn by a user.

Background Art

          Wearable electronic devices such as smart watches,
for example, become ubiquitous these days.

Disclosure of the Invention

          According to a first aspect of the present inven-
tion, a wearable electronic device is introduced, comprising a
sensor providing a sensor signal, which sensor is one of a
temperature sensor and a humidity sensor, and a control unit
configured to determine, subject to at least the sensor sig-
nal, if the wearable electronic device is worn by a user, and
configured to provide an output signal indicative of a result
of the determination.

          The wearable electronic device, which may also be
referred to as device in the following, may for example, be
one of a hearing aid, an earphone, a headphone, a watch,
glasses, goggles, a helmet, a shoe, a body-worn device such as
a leg-worn device or a belt-worn device, a fitness wearable, a
dedicated medical device, a safety device, a piece of clothing
also referred to as smart cloth, etc. In a different embodi-

ment, the wearable electronic device at least includes one of
the above items as wearable unit and in addition may include a
unit remote from the wearable unit which remote unit may be
portable, for example, such as a smart phone or a tablet com-
puter, or even may be a stationary device comprising computa-
tional capabilities.

          The term wearable indicates that the device or the
wearable unit thereof is suited to be attached to a part of a
human body, most of the times to a designated part owed to a
functionality and / or a shape of the device. For this pur-
pose, the device or the wearable unit thereof may comprise
dedicated attachment means such as a wristlet of a watch for
attaching the watch to the wrist of a user, or earpieces of
glasses for making the glasses rest on the nose of a user.
However, other wearable electronic devices or units thereof
may not show dedicated attachment means such as earphones, for
example, which may be inserted in the auditory canal of a user
solely based on their shape. Typically, a wearable electronic
device is in touch with a body portion of the user or has at
least a unit that is in touch with a body portion of a user
while being worn. Some wearable devices require a direct con-
tact to the body portion, for example, in case the wearable
electronic device comprises a medical sensor that relies on a
direct contact to the skin. Other wearable devices may be at-
tached to a body portion of the user but may allow a textile...
