Develop native applications for each platform Develop mobile web applications, so as to reduce the native code for each platform

3. Software for Wearable Devices 2017 Fall CS 2310 Seminar q Wearable devices collect real-time user Privacy information And Security (geographical location, living habits, heart rate, body temperature, account password and conversation, etc. ) q The communication of wearable devices is mainly based on wireless network. Thus, more private information may be easily attacked or stolen. q We can consider from the following aspects 1) Research on reliable network communication protocols 2) The system should have permission setting. 3) Reasonable software patterns should be proposed to solve these problems.

3. Software for Wearable Devices Wearable devices can only use battery, rather than stationary power. 2017 Fall CS 2310 Seminar The large amount of energy consumption for devices can produce great heat. Energy Consump tion Energy consumption management is an essential issue. q The control of energy consumption at each application layer 1) Reduce hardware electricity consumption through reasonable invoke of system APIs. 2) Create adaptive energy-sensitive applications to adjust automatically energy usage. 3) Adopt load-balancing method to transfer complex calculation to the mobile terminal via wireless communication network.

3. Software for Wearable Devices 2017 Fall CS 2310 Seminar q Ways for users to interact with wearable devices Human 1) Contextual Awareness Computer Interaction 2) Augmented Reality : apply virtual information to the real world 3) Non-keyboard input : non-keyboard ways such as voice, handwriting, gestures, data glove etc. q Ways to strengthen the human-computer interaction tech 1) Apply existing mature human-computer interaction ways (hand writing, voice and other non-keyboard input) 2) Strengthen the research of currently-immature humancomputer interaction ways(contextual awareness, augmented reality, mediated reality, etc. ) 3) Propose new human-computer interaction ways.

3. Software for Wearable Devices 2017 Fall CS 2310 Seminar Software q Some aspects/issues that may be of Engineering value and worth studying 1) Demand analysis : using user’s feedback 2) Code recommendation 3) Application transplantation : create API mapping among different platforms and develop an ideal compiler

3. Software for Wearable Devices 2017 Fall CS 2310 Seminar “ Big data and wearable device complement each other and pursue a common development ” Big Data We can gain a lot of useful information generated by wearable devices(basic personal information, health status, the preference to food, cloth and color etc. ) Big data analysis technology will provide a great help for scientific research, social development and users’ life. Compared to mobile phones, wearable devices will produce larger amount of data. So it needs big data technology to deal with these collected data even more. Wearable Device

3. Software for Wearable Devices 2017 Fall CS 2310 Seminar “ Big data and wearable device complement each other and pursue a common development ” Big Data The analysis for heart rate and blood pressure can understand user’s body status and potential risks. Wearable devices need big data technology for processing these data to provide useful information to users. Wearable Device

4. Conclusion 2017 Fall CS 2310 Seminar q Wearable devices dramatically change modern way of life q The development of wearable devices is still in its immature and limited stage q Especially, application software development is still in the initial stage.
