Design Summary & Analysis Final Draft (improved from Professor Blackstone's comments)

In the article entitled "Force-Sensing Gloves Cloud Control An iPhone By Detecting Gestures and How Objects Are Gripped," Owen (2019) mentions that Apple wanted to create a glove technically capable of engaging with technologies for individuals. This glove is made of fabric meshed with conductive layers that sense the forces applied in the glove when the user touches a surface. In addition, this glove will detect how much pressure is applied and the number of fingers used. The author also states that Apple will look at different ways a user can control an application without interacting with the touchscreen. The glove will include conductive strands that are woven together with normal threads and thus able to monitor contact outside while the inside contains sensors for compression from the fingers. Owen also adds that it opens opportunities to replace handheld controllers in VR and AR.

While Owen provides substantial details on what material is incorporated in the gloves and how electronic components are integrated together in the gloves, he fails to describe how the gloves will be of inconvenience.

Firstly, Owen fails to provide details on the bulkiness of the gloves. In an annual conference report by Tam et al. (2004), there is a technology developed for tracking of muscle movement, but it is too bulky. Wireless electrodes are attached to the skin recording electrical activity of the muscle tissue these sensors are also known as electromyography (EMG), converting muscle contraptions to a voltage which measure applied forces by the hands.  However, this device consists of one transmitter and a receiver both which are somewhat the size of the hands and are too bulky to be carried around. Hence it will not be very practical for Apple to create this force sensing gloves. Also, Cecil, Kanchanapiboon (2007) further support how bulky the gloves might be. In this article, Kanchanapiboon discusses the use of a virtual reality (VR) system to help in the assembly and disassembly of items in the workplace, which consists of a set of gloves connected to a VR set. However, the user will have to carry the entire VR system around, and this setup would be too bulky and heavy for practical use. Hence, this shows that force-sensing gloves are too bulky with the current technology available and will be of inconvenience.

However, having large transmitter and receiver can be of inconvenience. the article by Spliz et al. (2019) mentions that the force- sensing gloves in the article is using a type of fabric that can sense pressure and is light-weight. The glove measures the force applied by the patients going through physiotherapy, by using this glove it will give them a more objective visualization of their healing process. The device uses a sensor they developed based on piezoresistive fabric where electrical resistance changes with force applied. Not only that but the fabric is also light and flexible. Using Flex Sensor by Spectrasymbol on joints sensing the bending of fingers. With these sensors incorporated in on each joint, which can determine how the force is applied and show how items are gripped. We can deduce that the material and size of sensors are small making the force-sensing glove more feasible and more desired by not only people in the medical industry.

In conclusion, more research is needed for the force sensing gloves. Although the size of the transmitter and receiver can be reduced as technology advances, there are still other issues to be tackled. Force sensing gloves may soon be worn by everyone one day.
