  • Administrative Memorandum County of San Mateo
    ADMINISTRATIVE MEMORANDUM COUNTY OF SAN MATEO NUMBER: B-19 SUBJECT: Mobile Technology Use Policy RESPONSIBLE DEPARTMENT: County Manager / Clerk of the Board APPROVED: _____________________________ DATE: _May 5, 2014____ John L. Maltbie, County Manager This memorandum replaces an earlier version of Memorandum B-19 dated October 22, 2007, which was limited to the acquisition and use of cellular telephones and personal digital assistants. This memorandum revises and expands the policy to cover the County’s acquisition of “mobile devices” and provision of such devices to employees. This memorandum also covers the use of such mobile devices to transact County business (including but not limited to accessing County information systems and technology) whether such devices are County-provided or personally-owned. It is San Mateo County’s policy that both the operation of County-provided mobile devices, as well as access to County information systems and technology from personally-owned devices, be appropriate and beneficial to the County and, by extension, its residents. The term “mobile devices” includes not only cellular telephones and personal digital assistants, but also smartphones, tablets and other mobile technologies. Under this policy, County Departments may choose to either provide County-supplied mobile devices to specific workforce members or authorize specific workforce members to access the County’s information systems and technology with their personally-owned mobile devices. In either case, such authorized workforce members will be required to meet the specific requirements of this Mobile Technology Use Policy. It is the responsibility of each Department Head to provide a list of authorized department users to ISD on an annual basis.

  • Kimono: Kiosk-Mobile Phone Knowledge Sharing System
    Kimono: Kiosk-Mobile Phone Knowledge Sharing System Albert Huang1 Kari Pulli1,2 Larry Rudolph1 1Massachusetts Institute of Technology 2Nokia Research Center Abstract The functionality of an information kiosk can be extended by allowing it to interact with a smartphone, as demonstrated by the Kimono system, and the user interface can be greatly simplified by “associations” between pieces of information. A kiosk provides information that is relevant to a particu- lar location and can use valuable context information, such as the fact that a user is physically standing in front of the kiosk, to tailor the display. Its graphically rich screen is suit- able for presenting information to the user and has a natural input modality requiring the user to simply touch the screen. However, a kiosk lacks mobility and cannot stay with the user as he or she moves about the environment. Also, infor- mation provided by the kiosk must be remembered by the user. Finally, it is difficult to add information to the kiosk, and so the kiosk remains an information display device. All this changes when a handset, such as a PDA or smart- phone, can interact with the kiosk. The handset acts like a personalized proxy of the kiosk. It accompanies the user serving as a memory device. It is also an excellent media cre- Figure 1: The OK-net terminal with a touch panel display ation device, capable of taking pictures and recording voice and an optional keyboard. memos as well as short text messages.
