Ergonomic tablet holder

An adjustable holder assembly for use with a computer device having a user interface portion, and having orthogonally oriented first, second and third axes, wherein the first and second axis are substantially parallel to the user interface portion, and the third axis is substantially perpendicular to the user interface portion, the holder assembly comprising:

• a mounting structure;
• a display support rotatably coupled to the mounting structure for rotation about an axis of rotation, the display support having a center of gravity, the display support comprises:
• a support structure connectable to the computer device, wherein the display support and the computer device are rotatable as a unit about the axis of rotation in response to a user pressing against an input portion of the computer device at a location spaced apart from the axis of rotation;
• and
• an adjustable counterweight assembly connected to the support structure and having a counterweight and an adjustment mechanism connected to the counterweight, the counterweight being spaced apart from the axis of rotation, the adjustment mechanism being adjustable to move the counterweight in a direction normal to the axis of rotation to move the center of gravity substantially parallel to the third axis toward or away from the support structure;
• wherein the adjustable counterweight is configured to provide a force feedback to a user pressing on the input portion of the computer device, and adjusting the counterweight to move the center of gravity toward the support structure decreases the force feedback, and adjusting the counterweight to move the center of gravity away from the support structure increases the force feedback.

An adjustable holder assembly for use with a computer tablet having a display screen with a user interface portion, and having orthogonally oriented first, second and third axes, wherein the first and second axis are substantially parallel to the display screen, and the third axis is substantially perpendicular to the display screen, the holder assembly comprising:

• a mounting structure;
• a tablet support rotatably coupled to the mounting structure for rotation about an axis of rotation, the tablet support has a center of gravity and comprises:
• a support structure configured to removably retain the computer tablet with the first axis substantially coincident with the axis of rotation, wherein the tablet support structure and computer tablet rotate as a unit about the axis of rotation and relative to the mounting structure in response to a user applying a force to the display screen at or adjacent to the user interface portion at a location spaced apart from the axis of rotation;
• and
• an adjustable counterweight assembly connected to the support structure, and having a counterweight and an adjustment mechanism, the adjustment mechanism being substantially aligned with the third axis and being connected to the counterweight, wherein the adjustment mechanism is adjustable to move the counterweight relative to the support structure and move the center of gravity substantially parallel to the third axis toward or away from the support structure;
• wherein adjusting the counterweight to move the center of gravity toward the support structure decreases a resistance of the tablet support to rotate about the axis of rotation, and thereby providing a force feedback to a user pressing on the user interface at a location spaced apart from axis of rotation and in a direction substantially parallel to the third axis.
