Touching a virtual agent involves more than detecting a finger on a display: the contact surface can deform and resist the user's push, and the agent can respond to that action. We describe the Desktop Amid Touch (DAT) screen, which combines spatial projection onto a semi-transparent, deformable mesh with touch sensing and motorized control of resistance to indentation. An initial prototype detected a single touch and estimated its position and depth from tension changes around a flexible projection screen. A subsequent prototype added motorized tension control to vary the screen's resistance to indentation. We describe the tension-controlled DAT implementation and its demonstrations, distinguishing what has been observed from what remains an open design question. These capabilities raise a design question: should touchable virtual agents respond as though they had preferences or boundaries, and under what conditions should such behavior be implemented on systems like DAT. The present paper describes a system and frames this question; it does not establish how users interpret an agent's refusal or consent.
