A device includes a display and an internal strap coupled to the display, the internal strap being adjustable to secure the device to the user. The device also includes a deformable material coupled to a portion of the internal strap and configured to contact the user when the device is secured to the user and a backing layer disposed against the deformable material, the backing layer including an aperture therein. The device further includes a switch coupled to the backing layer and configured such that at least a portion of the switch is insertable in the aperture of the backing layer, wherein the deformable material is configured to deform when the device is secured to the user, thereby causing the switch to be positioned in a first position when the device is secured to the user and a second position when the device is removed from the user.
