The image I recently uploaded of the "Xeel" remote(s) comes from an archived version of a Directions on Microsoft page which states:
"Simpler devices, such as Smart Personal Objects Technology (SPOT) watches and alarm clocks, would feature a basic Xeel interface (shown at left) with an up and down arrow for navigating through lists and menu options, a green "Enter" button, and a red "Out" button that would close programs or otherwise let users escape from their current task. More complex devices, such as Tablet PCs, would have additional buttons (shown at right) to let users perform tasks such as moving back to a previous screen, switching between windows, and displaying additional menu items."
However, an official transcript from WinHEC 2003 suggests that all devices would make use of a single remote design, which would have been more in-line with Microsoft's goals at the time for a consistent user experience. In addition, page 20 of a Microsoft PowerPoint slide titled "Creating Demand Through PC Innovation" shows only one Microsoft "Xeel" remote.
"CORY LINTON: Exactly. XEEL is about having this common navigation experience on Media Center, remotes, phones, a tablet PC. I can scroll through Outlook using the same kind of UI that I used on a SPOT device. So exactly, it's having this consistent experience so users don't have to learn something new every time."
