II. Allion Labs Inc. Comparison of Smart Watch Integration

Smart Watches presently being sold are primarily an extension of the Smart Phone and need to interconnect and pair with either tablets or Smart Phones first before being able to be controlled by Apps. Because of this Allion Labs separated tests terms on the Satisfaction Survey on Apps and Smart Phone from the test on functionality. SONY is the only Smart Watch with the capability of pairing with Smart Phones using Bluetooth through NFC which is built-in and can be connected by just a click therefore earning the highest usability of pairing process ranking as well as ranking highest in 'operation interface' and 'usability of APP'. (Allion Engineering Services, 2013, p.1) SONY additionally performs better in the categories of 'basic function', 'SMS notification' and 'Mail'. However Martian rates high in the category of 'incoming call notification'. (Allion Engineering Services, 2013, p.1) Martian is the only Smart Phone able to perform voice dialing and that has the capability of picking up the incoming call and conducting conversation through the built in noise canceling microphone and speaker however the voice-dialing function on the Martian Smart Phone is reported to be inaccurate with a high rate of failure due to the voice control not being supported in the areas of the user's residence. Currently Smart Watches play a role that primarily assists with Smart Phones via Bluetooth technology informing users when smart phones are in receipt of new notifications or have incoming calls. It is reported to be clear that all of the Smart Watches have "IOP problems with corresponding smart phones. For example: SONY cannot receive Mail and Facebook notifications from LG Nexus 4; SONY XPERIA Z. receives Facebook notification but Martian does not." (Allion Engineering Services, 2013, p.1) The Allion experts report results indicating that Smart Watch companies "...need a multi-angle IOP test plan to make sure smart watches can work well with smart phones and to level up product quality and user experience. Moreover, Allion's Bluetooth Qualification Expert (BQE) finds out that although Martian Passport Watch claims that it adopts Bluetooth 4.0 Low Energy technology, but actually there is no available profile that can perform Low energy technology based on the test result. Despite Pebble lays claim that its smart watch is equipped with Bluetooth 4.0 technology, there is a discrepancy because its spec is Bluetooth 2.1+EDR, which differs from Pebble's claim on its website. Thus, developers need professional Bluetooth certification test and consultation service to ensure that products follow Bluetooth spec regulations and are able to work correctly with other devices." ((Allion Engineering Services, 2013, p.1)

The overall review of each of these phones is reported as follows:

(1) SONY Smart Watch 2 -- This is reported to be a product that is stylish and highly scalable and to have general good performance in terms of user interface. All the APPs on Smart Phones must be installed one at a time by users making first-time uses very complicated and consuming a great deal of time. The sleep mode is reported as such that fails to adopt the "smooth fade-out design and this would confuse users, to doubt whether their product is facing a crash or monitor encounters problems. After testing APPs of some famous social networks, we find out that users cannot set all posts on Twitter as read and SONY might lose Facebook notifications or have notifications delay. Besides the malfunctions, we suggest that it would be more user-friendly if users can adjust the location of APP on the monitor freely and the monitor can sense light and adjust lightness automatically. Also, It would be better to have voice control function too." (Allion Engineering Services, 2013)

(2) Martian Passport Watch -- The watch dial is reported to be too large and uncomfortable for wearing and the connection failure rate on Bluetooth to be too high. Some of the APP functions do not work as they should. (Allion Engineering Services, 2013)

(3) Pebble Smart Watch -- It is not convenient to download data to the smart phone first and then to change it over to the Smart Watch making APPs difficult for users to install. In addition, 11 MB-size APP is reported as relatively big and the interface reported as too simple with too many instructions in word form in the setting page making the readability difficult for users. There are no instructions in the installation mode informing users about which pushers to use and the largest shortcoming is the lack of support for multi-languages. Finally, even after termination of the connection the APP on The Smart Phone continues searching for devices and this results in high power consumption on the Smart Phone. (Allion Engineering Services, 2013)

III. Advances in Smart Watch Technology Integration

The work of Ping (nd) reports that the "development and application of inertial sensors" resulted in the evolution of the Smart Watch int a new generation of watches that supports "gesture-based interaction with both users and their environment." (p.1) It is reported that while Smart Watches make provision of "both traditional interaction and gesture-based interaction" there are still "some gaps in this area, such as security protection and standardization to be considered and filled." (Ping, nd, p.3) It is reported that the majority of Smart Watches only have one segment for display however, the Facet is a watch with multi-display segments. It is reported that each segment in Facet is important and can be utilized to store various information including incoming telephone calls and email.

In addition, Facet is Bluetooth powered and in some cases have infrared interfaces allowing the user to access Internet services easily. The segments of Facet are such that can be customized by the user. When the appropriate sensors are used the Facet can be integrated and interact with the user and the user's environment. Smart Watches can be used for remote control in some cases. (Ping, nd, paraphrased) The core component to the Smart Watch is the microprocessor. (Ping, nd, paraphrased) Sensors include: (1) accelerometers which make provision of relative position information and used to recognize gestures such as tilting, shake and swipe gestures. (Ping, nd, paraphrased); (2) Gyrocropes -- these are described as high-end solutions which provide relative orientation information by calculating the angular rate. Combined with other sensors such as magnetometers, they are possible to provide absolute orientation information. They are usually used to detection rotation of the forearm." (Ping, nd, p.5); (3) Magnetometer -- these are used in tilting gesture recognition and pointing gestures. (Ping, nd, paraphrased) Most Smart Watches are configured with a wireless module. The All-In-One Smart Watch has processing capabilities that are powerful and able to negotiate computational tasks that are intensive. (Ping, nd, paraphrased) dWatch is described as a Smart Watch that is integrated into a smart environment "though Dog, a domotic gateway that enables integration of different home automation solutions." (Ping, nd, p.6) The development of the integration involved a new device driver that is installed in the Dog gateway and utilized to communicate over a wireless protocol with dWatch.

Recommendations

In order for the Smart Watch to be user-friendly and to be functionally integrative it is likely that new drivers will need to be developed and others adapted so the Smart Watch can negotiate the extensive complexity that users desire in a Smart Watch. Some of the capabilities are already present but others have yet to be functionally optimized.

Conclusion

The Smart Watch holds great promise if the technologies needed to make these devices all that they have been hoped to be realizes success. The display on Smart Watches is far too small with too few segments and too much information crammed into single segments. The Bluetooth capability on many of the Smart Watches fails in connecting all too often. It is difficult for users to load APPs tot he Smart Watch and integration between the Smart Watch and Smart Phone leaves a great deal to be desired.
