Design Summary_Analysis Draft 2
In the article, "Force-Sensing Gloves could Control an
iPhone By Detecting Gestures and How Objects Are Gripped," Owen (2019) has
stated that Apple aims to enable people to interact with devices using any form
of clothing made using conductive strands in the fabric, such as gloves, which
provide force-sensing capabilities. The article describes how a glove could be
enabled to check how much force and with how many fingers a user presses a
surface, delivering different commands. The clothing would incorporate
conductive strands, interwoven with normal threads in the fabric, which allows
the sending of electrical signals from one section to another. The conductive
strands are connected to force sensing circuitry whose signals are sent to a
wireless element to send commands or other information to a main device. The
article also states that Apple has also thought of adding these fabrics with
flexible displays to create smart clothing.
Although the article does a decent job at describing the
concept and features of the Apple patent, it fails to discuss the disadvantages
a user will face when using the device, such as real-time wireless control and
ease of usage.
Regarding real-time wireless control, the article “Toward
Real-Time Control in Future Wireless Networks: Communication-Control
Co-Design,” Zhao et al. (2018) states that “real-time wireless control is
supported by both control systems and wireless systems, which tightly interact
with each other via some critical variables.” These variables include time
delay and packet loss. The article describes that a normal real-time wireless
system usually consists of “sensor-controller link delays, controller-actuator
link delays, and controller’s processing delays”. These delays normally
comprise delays in broadcasting, getting data to the distribution network, and
delivery delay, which are linked to many elements. An extremely long time delay
may weaken the system functions or potentially cause a system breakdown. The
article also mentions how packet loss, which is caused by a poor channel
capability resulting in incorrect translation of information, may result in
resending or decreased data transfer. In such devices, the packet loss would
result in higher costs as the system is required to make additional processes.
In another article “Disadvantages of Using a Wireless
Keyboard”, Weedmark (N.D) states that using a wireless keyboard or device has
its disadvantages in setup and batteries compared to their wired counterparts.
The article describes that where a wired keyboard can be used simply by
plugging it to the computer, a wireless keyboard often requires additional
configuration such as pairing or the need to download and install external
software. Another disadvantage stated is that wireless keyboard or devices use
batteries which require periodic charging or replacement, which can be a source
of annoyance especially while in the middle of an urgent task.
However, such a device is advantageous to many different
applications. Gesture recognition is a communication technique that performs a
large role due to its frequent use of “gestures and signs” for human
interaction. A plethora of usages are currently engaged in “gesture recognition
systems, such as sign language recognition, substitutional computer interfaces,
socially assistive robotics, immersive, gaming, virtual objects, remote
control, medicine-health care, etc” (Ahmed et al., 2018)
Although such a device brings about the potential for many
new applications such as AR or VR, they can only be considered feasible after
discussing the disadvantages and difficulties such as real-time wireless
control and battery life.
