Highlights:
- Family members and caregivers can know from a mobile terminal and PC, the exact location of the person wearing the Nock Senior bracelet.
- The location system is very accurate, especially outdoors.
- The call between the family member's terminal and Neki's watch works in hands-free mode with a good speaker.
- Typical locations can be detailed for the location system to automatically identify.
- The possibility of configuring personalized alarms or notices for each user of the bracelet.
- You have the option of sending text messages to the bracelet, to reassure or warn the person wearing it.
- It is an everyday and discreet device, for people of Gender Violence there is also a lot of potential, due to the normalization of such a simple device.
Improvement points:
- Currently the device is designed so that end users cannot turn it off, it is proposed that this option be customizable depending on the person who uses it.
- In relation to the web, it could be interesting that the history of the positions where the bracelet is located could be shown according to a time interval and also in a textual format as well as on a map.
- Regarding the configuration of the alarm notifications, they could be customized to be a reminder for other things, such as taking medication, for example.
- Both for the mobile and web application, the possibility of being able to configure aspects of the Web could be incorporated: font size or color of the Web background.
- As accessibility improvements: if the device were offered to other types of groups, for example for people with partial or null vision, it would have to offer other configuration possibilities: such as vibration, auditory notifications about the processes, or compatibility with their own devices mobile phones or assistive products. In the case of deaf people, the same limitation is identified, a feedback of the actions that are given in the terminal would be optimal, for example through the clock screen, so that the user is informed at all times.

Family member or caregiver: This profile will use the Nock mobile app and the web.
WEB: The web application is where the most relevant aspects are configured, such as the contacts that can know the location of the bracelet, the safe areas, the location frequency or the warnings. An example of a WEB screen:

Alerts configuration screen
The mobile application, available on iOS and Android, is specially oriented to monitor the location of the bracelet in real time, although from it there are some parameters that are configurable:



Nock mobile app
The Android application has more than 1000 downloads and the opinions in the Play Store and Apple Store of the people who have acquired it so far are very positive.
Technical Features:
The Nock clock has worked correctly, as well as the applications of the relatives, on the web, tested in Google Chrome, Explorer and Firefox and on mobile, with Android. The mobile part can also be used on Tablet PC with a good screen fit and the web part on PC.
Consumption battery of the device, it is based on the use between 8 hours to 2/3 days.
In relation to the location GPS of the device, we will highlight that outdoors the solution has a very optimal precision, and when turning it on and off the location is fast and with a very low margin of error. Indoors, the location by the GPS system itself is less accurate. For indoor cases, the proposal is to map the usual sites and save their reference so that the WIFI of the physical location can be identified. In the event that the location is WIFI/GSM, it is an interior data, in the case of GPS it is the location of the exterior.
In relation to the data securityIn the management and use of the complete system, it is perceived that only the administrators who manage the person can access the tracking of the person. As an improvement aspect, the possibility of having two web access profiles is valued; one more focused on the profiles that manage the settings and adjustments of the person, and another that can only track the location of the watch.
Accessibility:
The device is accessible to the focus of people to whom it is directed. Proposing an operation based on two buttons and concise and simple information. It offers the possibility of launching emergency calls from the watch, by pressing one of the buttons. People with moderate manipulation difficulties could use the basic functions of the watch, but access to the contacts menu from the device would be very limited.
Regarding the Web part, the application is accessible with the main browsers. In order to extend the profiles of people who may be beneficiaries of Neki, it is recommended to check the accessibility of the Nock application with the main accessibility supports of mobile terminals such as VoiceOver or Tallkback.
However, we reaffirm that the solution, for the groups to which it is now directed, works in an accessible way.
