You can use following steps:

1. Pass input user value from your html form to Activiti using taskService.complete(task.getId(), taskVariables); taskVariables should contain variable with keys for example 'userId' or 'userIds' to access submitted values in process instance
2. Use expressions in your process definitions <userTask id="task" name="My Task" activiti:assignee="${userId}"/> or <userTask id="task" name="My Task" activiti:candidateUsers="${userIds}"/> to assign tasks
   
   Also look to http://www.activiti.org/userguide/#bpmnUserTask and http://www.activiti.org/userguide/#springExpressions for detailed information
