Abstract
A user input device for use with a computing device is provided. The user input device may include a housing with a bottom portion including a substrate that includes a transparent portion. The user input device may further include an optical tracking engine mounted in the housing proximate the substrate and being configured to transmit and/or detect light for tracking movement of the user input device through the transparent portion of the substrate.
Claims20
A user input device for use with a computing device, the user input device comprising:
- a housing with a bottom portion including a substrate that includes a transparent portion;
- and
- an optical tracking engine mounted in the housing proximate the substrate and being configured to transmit and/or detect light for tracking movement of the user input device through the transparent portion of the substrate.
A user input device for use with a computing device, the user input device comprising:
- a housing with a bottom portion including a substrate that includes a transparent portion, the substrate being configured as a touch sensitive input device;
- and
- an optical tracking engine mounted in the housing proximate the substrate and being configured to transmit and/or detect light for tracking movement of the user input device through the transparent portion of the substrate;
- wherein the optical tracking engine includes a light source configured to transmit light through the transparent portion of the substrate, and an optical sensor configured to detect light passing into the housing through the transparent portion of the substrate;
- and
- wherein the transparent portion of the substrate is transparent to the light emitted from the light source.
A user input device for use with a computing device, the user input device comprising:
- a housing with a bottom portion including a substrate that includes a transparent portion, the substrate including a touch sensitive layer and a display, wherein the transparent portion does not overlap with the display;
- and
- an optical tracking engine mounted in the housing proximate the substrate and being configured to transmit and/or detect light for tracking movement of the user input device through the transparent portion of the substrate;
- and
- wherein the optical tracking engine includes a light source configured to transmit light through the transparent portion of the substrate, and an optical sensor configured to detect light passing into the housing through the transparent portion of the substrate;
- and
- wherein the transparent portion of the substrate is transparent to the light emitted from the light source.
